The invention provides an enhanced intelligent card and a realization method thereof as well as a method using the intelligent card to realize fingerprint recognition function. The intelligent card coThe invention provides an enhanced intelligent card and a realization method thereof as well as a method using the intelligent card to realize fingerprint recognition function. The intelligent card comprises: a standard contact panel; a first processor used as an intelligent card controller; a second processor connected with a peripheral that is to be integrated into the intelligent card, and usedmprises: a standard contact panel; a first processor used as an intelligent card controller; a second processor connected with a peripheral that is to be integrated into the intelligent card, and usedfor interacting with and controlling the peripheral; and a gating switch connected among the standard contact panel, the first processor and the second processor and used for selectively connecting t for interacting with and controlling the peripheral; and a gating switch connected among the standard contact panel, the first processor and the second processor and used for selectively connecting the first processor with the second processor or the standard contact panel according to a switch control signal, wherein the connecting interface and message format used when the first processor is cohe first processor with the second processor or the standard contact panel according to a switch control signal, wherein the connecting interface and message format used when the first processor is communicated with the second processor are the same with those used when the first processor is communicated with the standard contact panel, and an open card operation system is operated on the first pmmunicated with the second processor are the same with those used when the first processor is communicated with the standard contact panel, and an open card operation system is operated on the first processor. According to the invention, more peripherals can be integrated into the card in the condition of not altering the card operation system, thus enhancing the functionality of the card.rocessor.
