Friction smart card connector

According to the general specification of IC card socket, SJ / t11166-1998

Spring contact, stable and reliable;

Both sides of the card holder are designed with inserted thin plates, which is convenient for customers to fix

There is spring contact protection design in the card holder to prevent abnormal card insertion and wire damage to the spring

Scope of application

Water, electricity, gas meter, card reader, digital TV set top box, IC card lock, IC card telephone, access control, etc

Network optimization information:

At present, most cpuic cards adopt t = 0 mode. T = O indicates that the data transmission mode between cpuic card and interface device (i.e. reader writer) is asynchronous half duplex character transmission mode.

According to the function of T = о protocol, the implementation of the protocol can be divided into physical layer, data link layer, terminal transport layer and application layer. Physical layer and data link layer can refer to ISO7816 standard. In the application of T = 0 protocol, it is not easy to separate the terminal transport layer from the application layer.

The terminal transport layer operates according to the process characters and status bytes returned by the card, so that the reader can process the data clearly. The process byte and status byte returned by the card are related to the usage of APDU (application protocol data unit) and VPP sent to the card by the application layer. It shows the process bytes returned by the terminal transport layer when the SIM card holder does not use VPP.
