Abstract: A wireless financial transaction verification facility has a transaction information terminal for scanning credit cards and entering a purchase price, and communicates information in a first electronic format. A converter is connected to the terminal and operates to convert the information to a second format transmissible by a digital cellular network. A wireless communication device is connected to the converter, and operates to communicate with the network in the second format. At a central financial agency, a similar converter may convert the information from the digital wireless transmissible format to a different format. Reply communication with approval or other information may proceed by the same means.
