1. a reader, including:

  • Contactless interface;

    Transaction modules, described transaction modules couples with contactless interface, wherein said transaction modulesIt is constructed and arranged to be less than between contactless payment devices and reader by following operationContactless transaction is carried out within the interaction time of 1/2 second;

    Send by answering that described contactless payment devices is supported to contactless payment devicesSelection;

    Receive for describing reading via contactless interface from described contactless payment devicesThe request of the data element of the ability of device;

    Send the data element asked to contactless payment devices via contactless interfaceIn at least one;

    The dynamic signature asking described contactless transaction from described contactless payment devices is testedCard;

    The response to dynamic signature is received from described contactless payment devices;

    Receiving the rear to described contactless payment devices transmission of the response to dynamic signatureREAD RECORD command messages for selected application;

    Terminate the communication with described contactless payment devices;

    WithContactless transaction is awarded after the communication of contactless payment devices in terminationPower;

    AndThe security module coupled with transaction modules, wherein said security module is constructed and arrangedBecome to prevent the intercepting to contactless transaction data and change, and wherein said dynamic signature is testedCard includes;

    The dynamic signature asked is received from contactless payment devices;

    Dynamic signature is confirmed by recalculating dynamic signature;

    WithOnly in the case of dynamic signature is identified, terminating and contactless payment devicesCommunication after, authorize contactless transaction.
