Patent attributes
A cardholder sleeve with selectable wireless communication capabilities is described. The cardholder sleeve includes two or more slots each configured to hold an integrated chip card. Each of the slots is surrounded by shielding material to shield the communication features of the card from skimming and prevent interference with other cards in the sleeve. The cardholder sleeve includes an internal card reader for each of the cards and a selection mechanism that enables a user to select a card in the cardholder sleeve for use. The cardholder sleeve further includes at least one transceiver in communication with the internal card readers that operates as a repeater to wirelessly transmit information read from the chip of the selected card by the respective internal card reader to external card readers such that the selected card need not be removed from the sleeve to be used.
