RFid Scanner

An RFid Scanner is the device which talks to or reads the RFid tag. An RFid tag is the label or item which holds the Identification number.  RFid is an acronym for Radio Frequency Identification. Typically its a tag or label affixed to something like a retail package.

RFid is basically the next thing after barcodes which we all know and love. They accomplish same thing, provide unique identifying number, but use radio communications instead of line of sight optical.

There are different types of RFid tags – which means there are different types of RFid readers. Some are called passive tags which means they are not active tags. Passive tags get their power from the RFid scanner while active tags get their power from a small battery.

RFid scanning can be done with a Rfid Handheld Scanner or a stationary Rfid Scanner. Stationary RFid readers are mounted in fixed locations while mobile RFid scanners are mobile computers with hardware which can interface with the RFid tag. Some readers add additional interface technology like a barcode scanner and are called a Rfid Barcode Scanner. If a magnetic card reader is added, then it would be called a Rfid Credit Card Scanner.  There are about a dozen other token reading devices attachable to a Rfid Scanner.
