RFID, the best solution for Automatic identification

Object tracking and management is the primary function of RFID tags. Radio Frequency Identification tags work on the mechanisms of electromagnetic fields. Till before RFID tags, bar codes were used in the Automatic tagging industry. Then the RFID inventory management solutions, proved such efficient, that it quickly replaced bar codes. RFID gained its popularity in the AIDC industry, completely based on the benefits of electromagnetic signal transmitting. The simple reason behind choosing RFIDs over pre-existing systems is its ability to carry information.

Barcodes and the likes, work on optical signals that are on a frequency lower to EM signals. Meaning they will carry lower volumes of data. On the other hand, X-rays, UV and gamma rays can also carry a huge volume of data. However, they care harmful to human health; automatically, leaving the RFID and its electromagnetic signals, the best choice in sight. 

The science behind RFIDs

The science behind RFIDs is very simple. They work on the fundamentals of signal transmitting and receiving. Hence, every RFID tag maker builds these tagging systems with three critical components. The small RFID labels are attached with the product to be tracked and carry digital information about it. A RFID receiver antenna, that communicates with the label on one end and a computer on the other. And third, an integrated microchip (also in the receiver), in which the product information is written.

How RFIDs work?

All RFID tags and RFID readers in India, work on the same logic. There needs to be a label attached to the intended product. And there needs to be a reader for signal transmission. Commonly, when a product arrives near a reader, the reader transmits signal through its antenna.
