Claim:
1. A computer-implemented method of conducting a financial transaction across a near-field communications enabled (NFC-enabled) point-of-sale device, the method comprising: detecting a first positioning of a mobile wireless instrument in operational proximity of an NFC-enabled payment instrument; establishing a first short-range peer-to-peer communications link between the mobile wireless instrument and the NFC-enabled payment instrument in response to detecting the first positioning; receiving in the mobile wireless instrument encrypted NFC-enabled financial data from the NFC-enabled payment instrument over the first short-range peer-to-peer communications link; storing the encrypted NFC-enabled financial data in at least one of one or more non-transitory storage mediums of the mobile wireless instrument; receiving in the mobile wireless instrument a temporary transactional encryption key from a server; decrypting the NFC-enabled financial data in the mobile wireless instrument by applying the received temporary transactional encryption key to the encrypted NFC-enabled financial data; storing the decrypted NFC-enabled financial data in at least one of the one or more non-transitory storage mediums of the mobile wireless instrument; detecting a second positioning of the mobile wireless instrument in operational proximity of the NFC-enabled point-of-sale device; establishing a second short-range peer-to-peer communications link between the mobile wireless instrument and the NFC-enabled point-of-sale device; and sending an instruction from the mobile wireless instrument to the NFC-enabled point-of-sale device over the second short-range peer-to-peer communications link to authorize the financial transaction.
