摘要:
A data transaction card having an interface for bi-directional contactless communication, and comprising a support (20) having a cavity (12) for accommodating therein a chip carrier module (10). The chip carrier module comprises a substrate (11) having a first side (45) and a second side (46), and an integrated circuit (30) mounted on the first side of the substrate for managing functions of the data transaction card. A coil antenna (40) is electrically connected to the integrated circuit for inductive coupling with a remote antenna, connections to the coil antenna being accessible from the first side of the substrate. The chip carrier module is packaged into one discrete unit so as to be amenable to mechanical assembly of the data transaction card without requiring additional electrical connections between the support and the chip carrier module during or subsequent to assembly. Such a construction allows for efficient mass-production of the data transaction card.
摘要:
A data transaction device having a contactless mode of operation and comprising an antenna coil (15) coupled to a processing unit (14) via an antenna interface (16) for allowing contactless data transmission between the data transaction device and a remote transceiver. A circuit within the antenna interface includes a modulator (45) for modulating a signal transmitted by the remote transceiver and received by the antenna coil with outgoing data generated by the processing unit for transmitting via the antenna coil to the remote transceiver. The circuit further includes a variable loading means (45) connected in series with a load (14, 58) seen by the antenna coil and having a capacitance (57, 59) connected across the load so as to effect a change in impedance of the load seen by the antenna coil thus allowing amplitude and/or phase modulation of said signal without complete interruption thereof and regardless of the magnitude of an external capacitance (59) connected across the load. Preferably, the antenna interface (16) may be customized for different applications and the data transaction device also includes a contact field (11) thus allowing for either contact or contactless communication.

The system comprises fixed triggering stations (2, 2') for short range data transfer with the smart cards in response to emissions from sensors (43). The sensors report data related to variables such as location, device status, operation sequencing and time. A send-and-receive station (3) allows for downloading of the stored data and for loading instruction sets in contact or contactless mode. The smart cards comprise signal amplification means (15, 44), transceivers (5', 40), a processor (8), memory (9), timing means (7), an on-board battery (4), non-compliance warning (42), as well as optional feedback and energy saving procedures.

A secured data transaction system (10) comprising a Smart Card Interface (SCI) (12) for interfacing between a local device (25, 26) and a Remote Secure Application Module (RSAM) (14) located remote from the SCI for processing data from smart cards. The SCI (12) comprises an SCI memory (28, 35) containing a predetermined instruction set, an SCI processor (15) coupled to the memory for operating in accordance with said instruction set, and a first SCI communication interface (16) coupled to the SCI processor for allowing bi-directional contactless communication between the SCI and the RSAM. The RSAM (14) comprises an RSAM memory (21) containing a predetermined instruction set and comprising a secured area reserved for security applications and for secure storage of data related thereto, an RSAM processor (20) coupled to the RSAM memory for operating in accordance with said instruction set, and an RSAM communication interface (19) coupled to the RSAM processor for allowing bi-directional contactless communication between the RSAM and the SCI. In such an arrangement data associated with the smart card interface (12) may thus be stored in the RSAM memory (21) remote from the smart card interface.
