RFID Chips Types Features and Leading Manufacturers

RFID chips are the tiny integrated circuits (ICs) found inside RFID tags or labels. Despite their small size, these chips are highly integrated, containing essential components such as a controller, memory storage, and a microprocessor. They operate by receiving power through the waves emitted by the antenna, and the RFID reader processes the stored data from the integrated circuit and transmits it.

With ongoing technological advancements, new RFID chips are constantly being developed, offering increased memory capacity and enhanced functionality. These chips provide a wide range of features, including password protection, data encryption capabilities, and integration with Electronic Article Surveillance (EAS) systems. Some chips even combine UHF RFID and NFC technologies, such as the EM4423 found in the Smartrac Belt DF tag.

– EPC (Electronic Product Code): A unique serial number designed to individually identify any object or product. This code can be customized according to user needs.

– User Memory: Allows storage of relevant information such as dates, product batches, expiry dates, and other important data.

– TID (Tag Identifier): A unique, non-modifiable identifier that ensures the singularity of each RFID tag globally. It is factory-locked and cannot be altered.

– Password Protection: A password can be set to prevent unauthorized individuals from reprogramming the chip.

– UID (Unique Identifier): Similar to the RFID TID, it is a unique and non-modifiable identifier that guarantees the uniqueness of each NFC tag worldwide.

– Password Protection: As with RFID, a password can be added to prevent unauthorized reprogramming of the chip.

– Memory: It offers the capacity to store data in 4-byte blocks. The standard encoding format is NDEF, which allows storing URLs, dates, product batches, locations, contacts, and more.
