Contact & Contactless (RFID) chip

Security meets versatility

Contact and Contactless (RFID) chips are electronic circuits embedded either on the card’s surface or in the plastic material itself. Contact chips placed on the surface are either memory chips used for data storage, in which case they carry identification details only, or microprocessor chips with memory and own operating system for data processing and sophisticated data protection.

Contactless (RFID) chips placed in between sheets of plastic are equipped with an aerial which communicates with card readers through Radio Frequency Identification (RFID) technology. These chips may also serve as ID carriers or alternatively for a two-way data exchange. Although the contactless version is more expensive, it is gradually replacing the contact technology in transport, access and payment systems mainly thanks to increased security and faster transaction processing.
