Abstract

A customer mobile personal point-of-sale terminal (CMPPT) includes a Point-Of-Sale (POS) sleeve portion that slidingly engages, and couples to, a cellular telephone. The cellular telephone is used to communicate encrypted information between a financial transaction verification entity (FTVE) and the POS sleeve portion. The sleeve portion includes a mechanism for reading in a merchant account number at the point-of-sale, and for communicating in a secure encrypted fashion with the FTVE via the cellular telephone portion. Rather than a customer entering sensitive financial information into a merchant's POS terminal (MPT) and trusting the merchant with such information, merchant information is entered into the CMPPT. The CMPPT initiates a transaction by sending the customer's account information and the merchant information to the FTVE. The FTVE receives information about the transaction directly from the MPT. The FTVE verifies the transaction, and after authorization, the FTVE forwards approval codes to the CMPPT and MPT.
