Proximity (125 KHz) cards are widely used in our RFID industry. The popular RFID chips are EM4200, TK4100 and T5577 etc.The typical thickness of such cards is under 0.84mm(0.033 inch).
With the ID card printer, customer personalizes Photos, Card Numbers and other info on the white-blank or preprinted proximity cards.
Due to traditional production technologies, many manufacturers produce the proximity inlay over 0.50mm thickness,finished cards' thickness over 0.90mm, which already exceed ISO standard!
In order to overcome such challenge and bring you the wonderful thermal printing results, combines with innovative technologies, RealSmart now launched the new solutions of Super-plain & Ultra-thin proximity inlay with 0.4mm thickness!
