IC card Study Notes (1)

Short File identification 3f in GSM as the main file
7f private files
The basic file EF 6f under the main file 2f is the basic file EF under the dedicated File
Private files under 5f private files

Multimode USIM, 3f00: 7f10: Telecom, 7f20: GSM, 7f25: CDMA

The returned status value is sw1sw2. If the maximum valid half byte is 6, the meaning of SW1 is unrelated to the application.

The 6e card does not support the command type.

The 6D instruction code is not programmed or invalid.

6b reference error

67 length error

6f does not provide accurate diagnosis

Transparent files are binary files. They are generally read and rewritten based on the offset and length in the file header.

A linear fixed-length record file. Each record is selected based on a similar record index.

Circular FileUsed to store records sorted by time series. When all the records have been used for storage

The storage will overwrite the earliest information. The EF of the cyclic structure consists of a fixed and equal number of records.

EF with linear fixed length structureIs composed of a series of records with fixed length and equal length.

Binary ef

An EF file consisting of a series of strings with a binary structure. Through the relative address (offset ),

A row read/write operation. The address consists of the starting address in bytes and the number of bytes to be read/written. Relative to the first byte of the binary ef

The address is '00 00 '.
