What is RFID?

Jan 27, 2012. 8:03 PMKaydenST says:

RFID stands for Radio Frequency Identification. It is pretty much used to transfer small amounts of data wirelessly. It is the technology used to set off the alarms when people try to steal things from grocery stores, libraries, etc. There are lots of other uses, like passports, ID tags, etc.
