Our RFID (radio frequency Identification) ID card printers utilise radio waves to automatically identify people or objects. This is one of the most common methods that is used to store a unique serial number that identifies a person or object on a microchip. Individual manufacturers have defined their own encoding methods such as Mifare, iClass and Legic. Smart cards operate at frequency of 13.56 MHz and have typical operating ranges of 10cm to 1m.
