The objective of this project was to specify, design and test the multifunction integrated circuits necessary to manufacture a low-cost smart-card-based identification system, consisting of a mobile, portable pocket-sized smart-card reader and a fixed terminal control unit. MORECO runs in combination with the MORESYS (5470) project in the ABHS-P area.
The objective of this project is to specify, design and test the multifunction integrated circuits necessary to manufacture a low cost smart card based identification system, consisting of a mobile, portable pocket sized smart card reader and a fixed terminal control unit.
2 integrated circuits have been designed in a first version:
a sensitive infrared receiver (SIRR) in bipolar technology;
a wakeup power supply (WUPS) in complementary metal oxide semiconductor (CMOS) technology. The SIRR integrated curcuit (IC) provides a single component receiver, incorporating amplification, filter and gain control functions, coupled to an infrared detector. The WUPSIC provides battery power management (the reader will be activated upon reception of an infrared pulse transmitted by the terminal).
Prototypes of reader and terminal, in the form of a smart card electronic badge and automatic control unit for hands free access control, have been fabricated and tested.
Further work is continuing to improve the power consumption characteristics of the badge, miniaturise it further, and decrease its costs.
Various studies are being executed to demonstrate the feasibility of increasing the system integration level for next generation smart card readers by incorporating the WUPSIC and the microprocessor on the same chip (including the necessary photodiodes) and to see if the infrared sensor diode and the SIRRIC IC can be mounted in the same infrared transparent plastic package with a lens on top.
The operating range is in the order of 0.5 to 3 metres, allowing communication whilst the person wearing the reader is moving towards the fixed terminal unit. This mobile data communication link uses a modulated, bidirectional infrared beam.
