0 Introduction
This standard is used to describe the parameters of the identification cards defined in Chapter 3 below and a series of standards for identification cards used in international exchange. The recording technique and coded character set for track 1 for alphanumeric data and track 2 for digital data are specified in GB/T15120.2.
1 Subject matter and scope of application
This standard specifies the track locations of read-only magnetic records (track 1 and track 2) on identification cards for automatic data exchange. 2 Reference standards
GB/T14916 Physical characteristics of identification cards
GB/T15120.2 Identification card recording technology Part 2: Magnetic stripe GB/T15120.5 Identification card recording technology Part 5: Location of track 3 of read-write tracks 3 Terminology
The term "identification-card" given in GB/T14916 applies to this standard. 4 Location of magnetic material
The magnetic material should be located in the area shown in Figure 1. Approved by the State Administration of Technical Supervision on July 16, 1994, and implemented on March 1, 1995
5 Location of the coded data track
GB/T 15120. 4--94
Minimum edge
Magnetic stripe area

The coded data track 1 should extend between two straight lines of 5.66mm and 8.46mm from the nearest parallel edge of the card, and they cannot exceed the straight line of 8.97mm from the nearest parallel edge of the card (see Figure 2). The coded data track 2 should extend between two straight lines of 8.97mm and 11.76mm from the nearest parallel edge of the card. However, it cannot be less than 8.46mm from the nearest parallel edge of the card (see Figure 2). When the third track specified in GB/T 15120.5 is also to be encoded, the edge of the second track closest to the third track (including the influence of edge effects) shall not extend beyond a straight line of 12.27 mm from the nearest parallel edge of the card. mm

6 Start and end of encoding
GB/T 15120.4
The center line of the first data bit (start mark) shall be 7.44 + 0.51 mm from the right side of the card, as shown in Figure 3. The center line of the last data bit recorded shall not be less than 6.93 mm from the left side of the card, as shown in Figure 3. mmbzxZ.net

Additional notes:
This standard was proposed by the Ministry of Machinery and Electronics Industry of the People's Republic of China. This standard was proposed by the Electronic Standardization Institute of the Ministry of Machinery and Electronics Industry. This standard was drafted by the Electronic Standardization Institute of the Ministry of Machinery and Electronics Industry and the Financial Technology Department of the People's Bank of China. The main drafters of this standard are Shao Jian, Huang Jiaying, Wang Yunsheng, Liu Zhong, and Nie Shu. From the date of implementation of this standard, the former Ministry of Electronics Industry of the People's Republic of China Standard SJ/7.9026.1--87 "Identification Cards-Recording Technology-Part 4: Read-only Tracks-. Positioning of Tracks 1 and 2" will be abolished. 33
