Technical Examples
- A communication link is established between the smart card and a computer using a valid smart card communication protocol. A smart card communication device determines the valid smart card communication protocol used by a smart card by polling a communication channel using a plurality of smart card communication protocols until a valid acknowledgment message is received. A radio frequency circuit is configured to communicate with the smart card using the valid smart card communication protocol. A digital signal processor having at least two demodulators demodulates an incoming data stream produced by the receiver in accordance with the valid smart card communication protocol in a dynamically reconfigurable manner.
- A method and system that enables a customer to delegate or authorize another individual to perform a financial transaction is provided. This system uses a smart card and a biometric scanner or reader writer, or a biometric device without a smart card. The smart card holds personal and financial accounts information about the customer including a set of biometric templates of the customer. The second smart card owner is identified as the true owner of a smart card after the second smart card passes a biometric authentication using a read write device. The first smart card owner specifies the desired transaction that is to be performed by the second smart card. The delegated or authorized transaction created by the first smart card is encrypted and stored in the second smart card and/or to a remote back-end host server.
- A system and method for handling a query seeking information about computers of a network, where the query can be optimized in a way which limits the set of computers examined to a set smaller than all known computers. The query is examined to determine a limited list of computers to be accessed that would yield the complete result. If the query can be satisfied using data from a number of computers which is less than all of the computers in the network, then the number of computers which is less than all of the computers in the network is accessed to satisfy the query. In this manner, the data collection process for satisfying the query is generally more efficient than accessing all of the computers in the network.
- The present invention relates to a smart card reader (10) that enables a user to insert a smart card (20) into an open receptacle (15) that includes tabs (16) or a lip (32) that resiliently holds the smart card (20) within the receptacle (15). The present invention provides users a novel and useful design to reduce smart card abrasion as opposed to the card readers of the prior art. The present invention relates to a card reader (10) for usage with a smart card (20) comprising: a receptacle (15), where the receptacle (15) includes at least one open side; at least one placement tab (16), where the at least one placement tab (16) extends into the receptacle (15) and secures the placement of the smart card (20) in the receptacle (15); and a plurality of contacts (18) residing within the receptacle (15) where the plurality of contacts (18) connect to a smart chip (22) within the smart card (20) upon placement of the smart card (20) in the receptacle (15).
- Smart card security is enhanced by making the smart card a two-piece device. Both parts of the smart card contain copies of user data and a processor, which executes program instructions stored in the smart card half so as to give each part of the two-part smart card security and intelligence. Both parts must be in communication with each other for the data in either card to be accessible and useable. By separating the two pieces, data compromise is virtually impossible.
