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.
