A card may store data on an integrated circuit housed within the card. The card includes at least two antennas that are configured to transmit the data. The card may include a switch to electrically couple only one of the first antenna or the second antenna to the integrated circuit at a time. The card may be configured to send a first set of data through a first antenna and a second set of data through a second antenna, where together the two sets of data can be used to execute a transaction.
