Abstract
Abstract A portable credit card terminal interface is disclosed for verifying credit information. The portable credit card terminal interface is adapted to be removably connected to a credit card terminal and to a telephone station. The credit card terminal interface includes a D/C power storage device and converter for converting D/C power from the storage device into A/C power. The device also is capable of for transmitting A/C power from the converter to the credit card terminal and detecting financial information signals representing credit and transaction information. The device further includes a first circuit for receiving from the credit card terminal the financial information signals and a second circuit for receiving from the telephone station verification signals representing verification information from a host computer. Finally, the device includes a control circuit for controlling the converter as well as for controlling both the first circuit and the second circuit means. The control circuit controls the first circuit to route the financial information signals from the credit card terminal to the telephone station and routes. The control circuit controls the second circuit to route the verification signals from the telephone station to the credit card terminal.
