7 Tips for a Successful RFID Project

7 Tips for a Successful RFID Project 1200 628 Altis Teknoloji

The visits, we had done to our customers in the first years of our business, was not easy to handle. Only a few of the companies had accurate information about RFID Technology. Only some of them used to believe they could do frenetic things with RFID technology.People were dreaming of doing fantastic things with RFID like; to determine location in indoor and outdoor areas with 3-5 cents chips (I seeked for those chips and couldn’t found them for years ) ), to ring alarms with those chips, to track interior parts of trailers from space. The reason of these great expectations are the so-called experts, who visits some websites about RFID and call themselves ‘’experts’’, but this is not today’s topic.The customers who challenged us the most were the profile which had only a fair project experience and failed. Non-competent project partner, wrong determined targets, wrong measurement and evaluation criteria, unsettled RFID technical and practical standards and other reasons like those, innovative firms, who could not transcend the technology of the day, had frustration while consuming time and money. The most difficult part is to persuade the companies in favor of the usage of RFID again.

To tell the truth, RFID projects are difficult projects to handle. Thanks that we do not have any project, which was left over or resulted with a failure. This also does not mean that, all the RFID project requests from customers can be taken over. In some cases, it is better to implement barcode or GPS solutions rather than RFID. Moreover RFID is now wide spread but we still see unsuccessful RFID projects. For that reason, I would like to share some points with you to have successful RFID projects.

1-) Manage your expectations properly

You would like to use RFID technology at work. But how? First of all, you should analyze accurately your expectations from this technology and also the skills of RFID technology.

  • Does the expectations of your company match with the RFID technology?
  • Will you be able to really realize and implement things that you need with RFID Technology?
  • Is RFID really the required technology by the company?
  • Does your managers have crackpot expectations and demands about RFID solutions?

You should answer to these questions clearly and objectively.

Answering these questions correctly will work so well that you can avoid a lot of things that can cause failure in the future.

RFID will not fit you, instead, your solution must comply with RFID

2-) Re-evaluating the Processes

There is a quote, used by me frequently and one day I will ask for copy right; “RFID will not fit you, instead, your solution must comply with RFID’’ I strongly recommend you not to struggle, instead cooperate with this technology if you would like to have productivity. Because whatever you do, RFID will do what it does. So how can you get along with RFID technology? You ought to update your business processes, the way of doing business and your business canvas. Evaluating this process with a competent RFID consultant answering the concept, scope of the RFID project, project cost, how and duration of the project, will enable you to save time and money.

3-) Documentation

In Turkey, documentation and records management is not very reputable by suppliers, customers or the companies. Documentation is an important tool and task to do, very important and necessary!

We speak about the dreams and expectations of the company for hours and hours in the first meeting with our customers. As we approach to the end of the project, the expected/planned and realized work differ. This difference between the planned and realized are not welcomed well by the customers and suppliers. The supplier can stand many unnecessary points out of the project scope, may stand resource problems in order to increase customer satisfaction and commitment. On the other hand, the expectation of the customer may not match with the realized projects and confirmation-payment process can be suffocated.

For that reason, you have to be careful about the processes of procurement and project implementation. The tag properties/features, medium properties, the environment, reading performance expectations, software ERP/WMS integration are the topics, which should be detailed and agreed upon the articles of the written contract/agreement between the customer and RFID technology provider/supplier, which is you.

This essential approach in software projects is getting more and more importance in RFID projects, because besides the software costs; hardware and costful consumables are also in the business.

For this reason, always remember to detail, commit, agree and sign under tag features/properties, environment features/properties , expectations of reading performance, software ERP/WMS integration.

This essential approach, which is important in software projects, is more important in RFID projects, because in addition to the software expenditures hardware and costly consumables are also taken into account.

After the first visit to our customers, we use a form called Project Question form to the customers, who demand for new projects. Due to the tens of questions in the file, our customers can think deeply and thoroughly and they will be able to share many details with us at the beginning of the project. Verba volant, scripta manent; wiritings remain, but words fly away. Spoken words fly away, written words remain”.

4) Site Survery

Unlike barcode projects, a successful RFID project that you see in one business may not be successful in another business in the same industry. There can be many reasons for that. For an example an RFID reader which we didn’t have any problem in many fields, caused problems in a hospital with high electromagnetic pollution. UWB systems, deck phones, wireless devices and many unimaginable things can interfere with each other and this is not a subject that we can take a risk. It is known that it is difficult to read the RFID labels in metallic environments but the metal effect in the environment sometimes unexpectedly expands-distorts the reading areas of RFID tags and this can change the flow. In fact I would say that during the site survey, simple tests of the labels should be done, because not only the materials which the labels will be attached but also the label you positioned incorrect may surprise you.

5-) Pilot

RFID Projects are relatively expensive projects. You may have a good purchase and may have chosen the most optimum offer but none of these means that you will have an RFID project that works like a clock. You can ask candidate companies you want to work with to set up a demo. This is wise but inadequate. You many not determine the suitability of the designed RFID system for your company and your business processes with one hour or daily demo work. Companies generally do not prefer to pay for this type of experience, they mostly settle for demo. The supplier can not give the desired support to the customer who wants more because of its resources. In such cases, the best thing to do is to develop a pilot. A small-scale RFID project, which is defined as key points and covers processes where the performance of RFID systems is critical, can sometimes prevent you from losing big amount of money. It is better to start with a 10 unit pilot instead of jumping into a project which would cost 100 units. This will prevent problems that may occur in the future. Pilots are also a good starting point for a change in the working culture for the instution. Pilots where you can add even more value with the feedback that will come from your employees in the field can be upgraded to the next stage without any problems if you are satisfied with their small scale. Thanks to the pilot you realized that RFID project does not fit you in this stage? Do not worry! Instead of paying higher prices, you get this experience with a small pilot.

6-) Think Hybrit!

Of course you can provide significant added value within your company by commissioning RFID projects! However, the RFID models which are too good to be true are generally models with point to point integration models. If your supplier and customers are taking the advantage of RFID technologies, you can establish a global chain and benefit deeply from the blessings of RFID. But what if such an investment is not planned on the customer or supplier side? Don’t worry, no one says ‘’You’ve upgraded to RFID, so throw the barcode away!’’. Keep the barcode technology in the game to keep the chain going! In this way, you do not have any operational problems with your other shareholders who do not use RFID and your shareholders will not be adversely affected by the systematic updates you make as they proceed with the old fashioned barcode until they upgrade to RFID.

Hybrid identification technology also makes it easier to manage departments within your company. You may not have been able to convey all of your process to RFID both due to the internalization process of RFID as a company and financial concerns. In such cases, it will be possible to provide transitions with barcode. Also RFID printers can play an important role in your hybrid scenarios while they can print barcodes and RFID tags at the same time.

7-) Tag

Let me share a secret about RFID projects. The factor which affects the most whether an RFID project will be successful or not is RFID tags. Even tag technology sometimes determines whether a project will be executed or not. It is a critical decision whether tags are for multiple use or one shot in your project scenario. Apart from this active-passive tag decision will affect your budget in a dramatic way. The level of labeling (palet, parcel, box, product levels) can determine whether your project will be truly feasible or not. For all these reasons, you should constantly experience tag types, models and features on your site from the first stage of your projects and observe this criterion in your most optimal RFID scenario.

Barcode or RFID?

Barcode or RFID? 849 451 Altis Teknoloji

Yes, right; this question tires you. Although we have answered to this question for over 10 years, it is still worth to write this question as the first subject in our blog. Barcode or RFID, which one do you prefer?

My answer to this question is very clear; “It depends from project to project.” The right definition is, in order to select the technology, barcode or RFID; you have to put forward criteria and performance expectations clearly, frankly and evaluate according to your project.

Upon the nature of their technology, RFID tags’ performance depends on the features/properties of surface that they are attached on. However, barcode tags are not depended like RFID. If you apply RFID tags on the surfaces of metals or materials that includes liquids, you may need sophisticated and special solutions, due to the problems about reading of RFID tags.

Indeed in barcode technology there is no problem like that. However, the readability of barcode does not depend on the surface; metallic or liquid neighbored. Except the physically unreading of bars of the barcode; barcode is a smooth technology and easy to implement.

This situation should not hinder the distinctive business advantages of RFID Technology. RFID technology is used effectively and efficiently in many projects due to its advantages.

Primarily RFID enables many tags to be read in milliseconds. Think of the reading speed of barcodes in a conventional supermarket during a daily shopping. RFID enables tens of faster speed of the conventional barcode reading. Another strength and preferably of RFID is; tens, sometimes hundreds of RFID tags could be read at the same time in a second by eliminating waste of time and work load.

Second impressive feature of RFID is not having a field of vision necessity like in barcode technology. Barcode scanner needs to read the barcode bars, in RFID technology, it is not needed to have a clear sight between the tag and the antenna. RFID tags provides speedy reading without any problems even if it is behind materials like; plastic, paper, tree etc. E.g. it is impossible to read a box of textile products in couple of seconds with barcode technology. RFID provides this in a blink of an eye, which shortens the process, decreases work load and most important saves time in the assembly line or other processes.

In order to select the right defining technology, you have to put forward many criteria and performance expectations clearly and evaluate according to your project.

RFID’s third important advantage is, it enables much longer reading ranges comparing to barcode reading technology. As it differs according to its types and features, we had projects that we experience reading from 10 and even 20 meters with passive RFID tags. With barcode technology, it is rather difficult to perform such a task, even impossible. This situation should not be resulted with the desire of long distance tag reading, even a passion. This range issue is another topic of a blog, such an important problem. I would like to mention about this in the next blogs.

After all these words, lets turn to the intial point. Barcode or RFID? I strongly recommend you to leave the situation to the expert of the business. By contacting us, with our competent team, we can evaluate and decide together which technology, where to assemble, when to implement and how to apply . So that you will save money, time and resources.

Which one, Active or Passive?

Which one, Active or Passive? 1200 628 Altis Teknoloji

Person can speak about passive and active tags for hours and hours when asked, especially when a person is verbalist like me,

Luckily, in the recent years, our job is getting easier and easier. With the execution of RFID projects of our government in the highways, without explaining hours, we do simply say; “Active tag is OGS and passive tag is HGS. Rather short, but effective. With the merits of this, people, who are distant to RFID technologies, people can understand that active tags are big and thick, passive tags are thinner and smaller. Of course, some can think OGS is a better technology and HGS is worse, because of the unreadable occassions in the gates of the highways. I am also thinking about to share a detailed article about this in the future.

Yes, I had given examples to the types of tags very shortly, but some may ask for more details. Here they are.

Passive RFID tags does not carry an energy source, it gets its power from the energy of electromagnetic waves ıf RFID readers. Frequently, passive RFID is used in the fields of Supply Chain Management Projects, Pass Systems, Parcel/Package or Product identification and tracking. Passive tags are more affordable than active RFID tags, since they do not include, battery or expensive circuit systems. This enables RFID projects affordable and economically procurable for plenty of sectors.

These tags are passive as the name implies. It is nominated as passive and they wait still. The energy, that is sent by RFID reader to the antenna, is converted to radio frequency wave by the antenna and it transmits signals to the air to form a reading field for RFID. This transmitted signal is pulled to itself by the internal antenna on the passive tag. This incoming ardio frequency wave works reversely and it is converted to energy to produce energy to the tiny chip on the tag. At this moment, the chip, which has electricity, produces an opposite signal and it transmits, radiates this. The reader catches this signal and transforms it to data.

There are various types of passive tags. The ones, who can stand high temperatures or hard tags that can endure hard conditions. 125 kHz, 13.56mHz ad 868 mHz are the frequently used ones as of frequency.

The advantages of passive tags in a few points;

  • They are smaller
  • They are cheaper
  • Thinner and more flexible
  • They can be produced in various different types
  • They can work years since they do not have a battery inside

Good News, in the recent years passive RFID tags can be produced with developed sensors. Values like humidity and temperature can be measured by sensors, which do not need batteries, starts to work with the energy of the RFID tag. After producing the data, these sensors sends the data to RFID readers. I am also preparing a detailed blog for these type of products to be posted.

When we come to active RFID tags, they get their power of signal sending from the batteries inside of the tags. This means usually they radiate signal constantly. In the real-time tracking projects, it is ideal to use active RFID tags. They have a longer range of reading comparing to passive tags, nevertheless they are more expensive due to their technology. They usually work with 433mHz and 915mHz frequencies. Generally, we, engineers prefer to use 433mHz models, yet 433mHz models has a longer wavelength and especially they work better in metal or liquid based environments than the other tags.

Active tags have a power source in them, so comparing to the passive models, they can send signal to wider ranges. Also they have larger memory than passive tags.

Their batteries can last 3 to 5 years. Some of the companies design the batteries of the tags to be changed after the end of the life of the batteries. This is an advantage, because the tags could be used after changing the battery. Yet, some of companies’ batteries in the active RFID tags could not be changed. You have to be careful with this criterion in the initial offers and first purchase.

The operation principle of active tags are 2. They expect signal from transponder type tag readers. As they are answering the signal, they transfer the data in the chip of the tag to the reader. So that, the tag does not send signals to the environment perpetually and uses the battery efficiently and effectively.
i.e. OGS (Otomatik Geçiş Sistemi-Automated Pass System) tags works under this principle with a little tiny Lithium battery for more than 10 years.

The second type tag, called Beacon, sends signals to the environment with particular time intervals.
Open space fixture tracking and mining are the sectors that Beacon is used frequently . This type of tags consumes the batteries loutishly. That is why the producers keep the signal power relatively low to ensure the extension of battery life. (Circa max. 100meters in general.)
Active tags has high-performance batteries, that’s why, they can produce a wide range of X with sensors . Only sensors? In the market, you can find tags with different features; with GPS, with External Memory, even adaptors with Wi-Fi features.

Active RFID tags are expensive to use, hense the objects, that the tags are attached, are more valuable products. e.g. Containers, expensive and valuable fixtures and inventory used in Mining and Civil Engineering Sector. Their sizes are bigger than the passive tags, that is why more durable models are produced, so in this classification they are more adventegous than the passive tags.

The advantages of active tags in some points;

  • Owning longer reading range/distance
  • Having the inner battery, they can integrate with different types of sensors, even with GPS!
  • Active tags are more durable and they can resist in hard conditions

Some of the tag companies produce BAP (Battery Assisted Passive) tags. These are the passive tags powered by battery. Usually they are produced with 868 mHz passive tags. Due to the battery inside, they have an important long range of reading distance. Like the active trasponders, they turn to active with the signals coming from RFID readers and their battery lives are quite long. As of passive tags, sensors can be embedded in those BAP tags. They are not widespread like the other tag types, but they in the leading role of some success stories.
