A CONTACT-LESS SMART CARD READER SYSTEM AND A METHOD FOR CONTACT-LESS POWER TRANSFER IN SAID READER SYSTEM

摘要

The invention discloses a contact-less smart card reader system and a method less power transfer in the reader system. An additional energy source is added in the reader system and an energy receptor cell is provided in the smart card. The receptor cell is used as a power source for circuitry in the smart card. Additionally, the energy source in the reader is activated only in the presence of a smart card resulting in a power efficient design for the reader system.
