A global positioning system (GPS) card reader comprises a bus connection
interface, a GPS module, a universal asynchronous receiver transmitter
(UART) coupled with the GPS module and a complex programmable logic
circuit comprising a complex programmable logic device. The complex
programmable logic circuit connects with the bus connection interface and
comprises at least: a card information structural (CIS) memory, am address
decoder, a power control register, and a storage card coupling for
connecting a storage card.
