Cardholder sleeve and near-field communication proxy device for communication with integrated circuit chip cards

A method comprising:

• receiving, at computing device paired with a cardholder sleeve comprising a pocket to hold a card with an integrated circuit (IC) chip and an internal card reader positioned adjacent to the pocket, an interrogating signal from an external card reader to perform a transaction;
• in response to receiving the interrogating signal, transmitting, by the computing device, a request to the cardholder sleeve for information associated with the card held in the pocket of the cardholder sleeve;
• in response to the request, receiving, at the computing device, the information associated with the card from the cardholder sleeve, wherein the information is read from the IC chip of the card held in the pocket of the cardholder sleeve by the internal card reader and is encrypted by the cardholder sleeve;
• in response to receiving the encrypted information from the cardholder sleeve, decrypting, by the computing device, the encrypted information received from the cardholder sleeve;
• and
• sending, by the computing device, the decrypted information associated with the card to the external card reader to complete the transaction.

A system comprising:

• a cardholder sleeve comprising:
• a pocket to hold a card with an integrated circuit (IC) chip;
• an internal card reader positioned adjacent to the pocket;
• an encryption unit;
• a transceiver in communication with the internal card reader, wherein the transceiver is configured to receive a request for information associated with the card from a computing device paired with the cardholder sleeve over a first communication protocol,
• wherein, in response to the request for information received by the transceiver, the internal card reader is activated to read the information from the IC chip of the card held in the pocket via a second communication protocol,
• wherein the encryption unit is configured to encrypt the information read from the IC chip of the card held in the pocket, and
• wherein the transceiver is further configured to transmit the encrypted information associated with the card to the computing device over the first communication protocol, and
• a computing device paired with the cardholder sleeve, wherein the computing device is configured to:
• transmit a request to the cardholder sleeve for information associated with the card held in the pocket of the cardholder sleeve, and, in response to receiving the encrypted information associated with the card from the cardholder sleeve and prior to sending the information associated with the card to an external card reader, decrypt the encrypted information associated with the card received from the cardholder sleeve.
