RFID and barcodes are two distinct technologies with some similarities in their applications. The primary difference lies in their operational mechanisms. Barcodes employ a “line-of-sight” approach, necessitating the use of a scanner to read the barcode. Consequently, users must position the scanner in close proximity to the barcode for successful scanning. In contrast, RFID technology does not rely on “line-of-sight” and can read RFID tags within the range of an RFID reader.
Barcodes have certain limitations. If a barcode label is accidentally scratched, damaged, or torn, it becomes unreadable. Moreover, standard barcodes only provide information about the manufacturer and product, failing to identify the object itself or offer detailed product information. For instance, a barcode on a milk carton does not reveal its expiration date.
In contrast, RFID tags can address these limitations. RFID tags are capable of storing unique identifiers and can be read even when embedded within objects or protected by packaging materials. This enables RFID technology to provide comprehensive product tracking and control systems.
