New RFID smart card contactless communication technology

CEA-Leti has demonstrated the non-contact, high-speed interface of RFID smart cards.

Contactless smart cards were originally designed for verification applications such as bus tickets, bank cards, and access control. In these applications, data can be transmitted at low speed. Newer applications, such as transferring biometric data and multimedia file downloads, require faster data transfer. Leti anticipates this need in the market and has always focused on technologies that deliver faster speeds.

Leti has created a prototype of a complete phase modulation system, including readers and cards, with current speeds of up to 6.8 Mbit/s. The characteristics of phase modulation are better than amplitude modulation, and the speed can be much higher than the current limit of 848 Kbit/s.

Leti currently optimizes signal processing to achieve speeds in excess of 10 Mbit/s. It also discusses with the International Organization for Standardization (ISO) and works with GEMALTO to make the most of this work.

The high-speed contactless interface is the result of research conducted by Leti since 2003. The project ended in 2009 with the participation of 16 European companies and research units that developed a set of international standards related to electronic identities and mobile transactions and demonstrated the implementation of these standards. At the heart of this project is a high-level prototype of a new generation of electronic ID cards and SIM devices.
