RFID阅读器

RFID is very similar to the barcode technology, where you can check out the price of an object by running the barcode sticker through a scanner. After that, the price of the product is automatically added to the bill of the user. However, unlike the barcode system, RFID is a lot faster. This is because although the former system uses optical scanning, RFID uses radio waves to track a product. So, you dont have to place the tag exactly under the scanner, just pass the Radio Frequency scanner and the tagged product is identified and tracked.

There are two types of RFID readers - Fixed RFID and Mobile RFID. The difference is as obvious as the names! While Fixed RFID readers are placed in stationary positions like a toll booth, devices that can read RFID tags on the move are Mobile RFID readers.
