card (IC card/Smart Card)reader logic, writing firmware, hardware design The main emphasis of the wafer card, the card is a wafer institution has its specification, ISO / IEC 7816, the Division I entrusted the development and utilization of the wafer card to store customer information, then choose the EPP ROM based chip cards, the interface is ISO / IEC7816, actual internal EPP ROM is related to the electrical characteristics in accordance with the specification , So in this case the development of the moment, just pay attention to power, ground, data communications foot, foot communication time, this type of application is to facilitate the same equipment, features convenient multi-user, non-access cards, access cards in general, as well as secure coding of exchange this case software implementations, purely EPP ROM read data can be used as basic data storage card body. after testing the stability of the interface is fairly strong, hot-swappable.
