Advantages of RFID

RFID is short for Radio Frequency Identification. It is the http://en.wikipedia.org/wiki/RFIDew system of tagging merchandise items for inventory management. A RFID Tag consists of an RFID Chip combined with the antenna. The RFID Chip contains approximately 2 Kilobytes of data, which is enough to carry tagging information such as product name, SKU code, inventory, serial number and other details.

RFID is fast becoming the new standard and is very useful in grocery stores, it is a replacement for the bar code that exists on most products today. Big name stores such as Walmart have already started using this technology.

It has numerous advantages, you can simply purchase all your items in a bag and instead of scanning each item individually, you can scan the whole bag. Goods can be tracked in transit and for delivery on board, without having to install bar scanners and the trouble to face the bar code in the right way since the RFID readers have a 20 feet range, goods can be scanned from outside a truck if need be.

Another advantage of RFID tags is if implemented on ATM cards or Credit Cards, you don't need to swipe the cards on a purchase, while buying gas at a pump etc.
