Generally, PVC card and smart card surface printing and technology are basically the same, their biggest difference is that RFID card is embedded in an ordinary PVC card a non-contact chip, with a remote contactless radio frequency interface. The production process of the contactless cards is: printing → medium → synthesis → punching card → small card → punch card, inkjet code → quality inspection → packaging → shipment According to the current international standard, the standard PVC card size is 85.5mm*54.0mm, of which the thickness of the ordinary card is 0.76mm, the thickness of the magnetic stripe card is between 0.8-0.84mm, the following is to introduce the production process of PVC card.
