  • Patent number: 7705712
    Abstract: A fast data transfer collection system using message authentication and contactless RF proximity card technology in non-contact storage and retrieval applications. The system is generally comprised of Host computers (application computer systems), Target radio frequency (RF) terminals, and a plurality of portable Tags (“smart” or “proximity” cards). A Host provides specific application functionality to a Tag holder, with a high degree of protection from fraudulent use. A Target provides control of the RF antenna and resolves collisions between multiple Tags in the RF field. A Tag provides reliable, high speed, and well authenticated secure exchanges of data/information with the Host resulting from the use of a custom ASIC design incorporating unique analog and digital circuits, nonvolatile memory, and state logic. Each Tag engages in a transaction with the Target in which a sequence of message exchanges allow data to be read(written) from(to) the Tag.

  • Patent number: 7437560
    Abstract: A secure communication link is established between a smart card and a remote central computer system through a network by using security functions at the smart card and the central computer system. A smart card communication device facilitates the exchange of data between the smart card and a local processor by modulating data signals sent from the local processor and demodulating signal transmitted from the smart card. The local processor couples the data signals to the network while maintaining the secure data in its secure state. The secure link can be used to perform a smart card transaction.

  • Patent number: 6801787
    Abstract: A transceiver assembly is designed to receive a controller module or to be inserted into a controller module to form a portable smart card communication device. The transceiver assembly includes a transceiver and a connector to electrically connect the controller module to the transceiver. The controller module establishes a communication link between itself and a smart card by sending and receiving signals and data through the connector. Information is read from the smart card and forwarded to the controller module. Information is transmitted through the transceiver assembly and stored on the smart card. The controller module can easily be disconnected from the transceiver assembly for use with other transceiver assemblies.

  • Patent number: 6547148
    Abstract: A collision resolution system and method for enhanced non-contact automated data collection. The data collection system generally includes a plurality of portable fare tags or token (“smart”) cards and a stationary target terminal. Each tag exchanges a series of messages with the target terminal to establish a communication link for the transfer of financial or other data. Concurrently, each tag and the target terminal process the messages to provide collision resolution, thereby ensuring that only one tag, at any instance, establishes the communication link with the target.
