Network optimization information:

What are the unique reading methods of IC seats? The following is a brief introduction of these knowledge, I hope to help you. The read-write mode of IC seat is different from that of data protocol. ISO7816 fully defines the read-write protocol of asynchronous IC seat, and synchronous IC seat defines the protocol standard of reset response process. Fortunately, many IC seats use ISO7816 synchronous reset response protocol as their data reading protocol. What is the unique reading method of IC seat?

(1) The data reading process is divided into three basic processes: reset, segment positioning and data reading.

(2) The implementation of asynchronous IC block protocol, asynchronous IC block operation is relatively simple. Many of them have microprocessors. The operation of the card is only ATR process and COS command transmission and response process. Its communication protocol is strictly in line with the ISO 7816-3 standard. The standard format of asynchronous communication in ISO7816 standard is basically the same as that of computer. The initial speed of IC card in STB standard is 9600bps at 3.57mhz clock frequency, which conforms to the current asynchronous communication speed standard. In order to facilitate reading and writing, the data port of smart card connector and the asynchronous communication interface of IC card interface device constitute the corresponding half duplex asynchronous communication logic channel.
