摘要

A financial system includes a plurality of peripherals like a magnetic stripe reader, printer, and keyboard which are coupled to a personal computer by an adapter board which is inserted into an interface bus within the computer. Even though the financial application being run may be single tasking, the system is capable of running multi-tasking operations. An encryptor/decryptor processor, which is used in handling secure data, is located on the adapter board to minimize unauthorized access to the secure data.
