Radio Frequency Identification

Radio Frequency Identification searches and locates tags attached to objects. The tag stores details in electronic form for unique identification of the object which serves the same purpose as that of a barcode or a magnetic strip. The advantage of RFID is that it does not need to be positioned in a specific way like the other alternatives of it. RFID not only searches or identifies a tag but also collects the electronic information from the tag and stores it in the computer system with almost no human interaction.

Being from the online shopping era, if you’ve to waste your time with a cash counter personnel struggling with the barcode then it’ll surely spoil your mood. On the other hand, imagine a scenario where you buy all the necessary stuff put it inside the RFID scanner, it searches and identifies all the tags of the different items and generate the bill making our task easier and quicker.

Even though the RFID technology has been there for over 5 decades, it’s very recent progression has been to use it as a throwaway tag for goods. Reason for the slow popularity of RFID which took decades to come into commercial use is because of a lack of proper industry level uniform standards. Nowadays for a major bulk purchase, it can come down to few cents per device as well.

1.        Signals from two or more reader collide and create ambiguity.

2.        When there are too many tags in a small area making it difficult to distinguish between each
