This standard is the basic standard for IC card payphone system and is the basis for formulating standards for other types of IC card payphone systems. On the basis of this standard, standards for several types of public payphone systems have been formulated, as follows: - YD/T1189-2002 "Technical Specifications for Mobile IC Card Public Telephone Systems"; *--YD/T1227-2002 "Technical Specifications for Multimedia IC Card Public Telephone Systems" - YD/T1150-2001 "Technical Specifications for Intelligent Public Telephone Services"; ..YD/T1308-2004 "Technical Requirements for Intelligent Public Telephone Systems".

6. 3. 2 Safety module use process
Leave 5 physical dimensions of the safety chess piece
6.3.2. Workflow when using the safety module The workflow should comply with the provisions of Figure 6,
ur La t1 The chip and card manufacturer code area is applied for by the telecom operator to the government department in charge and the manufacturer is entrusted to encode. 6.1.4.2.2 The encoding rules of the issuance code area are formulated by the telecom operator. 6.1.4.3 Data in the counting area
6.1.4.3.1 The counting area is used to store the counting units corresponding to the amount on the card. 6.1.4.3.2CO to C4 are five-level counting devices, using the base-level 8 counting method. Each bit of CO to C4 represents 1, 8, 64,512.4096 full counting units respectively, and there are 210640 units on the card. 6, 4.3.3 When counting down, each level starts from the low bit (address) to write (write 0), and after the whole level is written, it is erased by carrying the adjacent high level (to 1), and C4 cannot be erased.
6.1.4.3.4 When writing the initial counting unit of the card, each level starts from the low bit (lower address bit) to write out the redundant units. 6.1.5 Other requirements
6.1.5.11 IC card is a prepaid value card. The data on the card should be retained for more than 10 years. 6.1.5.2 Both the front and back of the IC card can be printed with text and patterns. The front side should be printed with a clear insertion direction mark and IC chip as a person identification mark.
6.1.6 Card inspection and testing method
Carry out in accordance with relevant ISO standards.
6.2 Technical requirements for user IC cards with security authentication mechanism Its physical and electrical characteristics should comply with the requirements of ISO7816. The algorithm is determined by each telecom operator. 6.3 Technical requirements for security module
6.3.1 Electrical signals and physical characteristics
