Contactless smart cards use radio frequency identification (RFID) technology to wirelessly communicate with a card reader. A copper or aluminum antenna is connected to an integrated circuit (chip) and then securely laminated inside the plastic card body under high heat and pressure. Contactless smart cards range from simple memory cards with low security and non-volatile memory structure up to high security crypto-processor cards and Java / Native operating system (OS) cards. Cardzgroup uses specialty formulated PVC and PET that allows us to manufacture the thinnest ISO contactless cards while eliminating the antenna and chip blemish found on many lower quality smart cards.
