Abstract

The invention relates to the electronic payment and information safety field, and discloses interface conversion equipment communicating with a safety device used for calculating electronic payment codes and a method thereof. The invention is primarily used for interface conversion when the invention communicates with the safety device to calculate the electronic payment codes. The invention can effectively ensure that a PC computer or bank computer terminal equipment connects with and communicates with the safety device in USB-key mode to calculate the electronic payment codes; mains input can be provided for the safety device to calculate the electronic payment codes during communication. At the same time, the equipment can also independently support the connection with prior hand-held electronic payment coder equipment through standard serial port transfer lines, and is compatible with such operations and functions as initialization and loading account information of prior hand-held electronic payment coder equipment at the bank terminal.
