When debugging a 470 card in Bangladesh, it was found that this card is a bit similar to the card of China Telecom, but it also has two aids. The following data
=>0x00 0xa4 0x00 0x04 0x02

You can see aid1 is
0xa0 0x00 0x00 0x00 0x87 0x10 0x02 0xf2 0x30 0xff 0x01 0x89 0x07 0x02 0x00 0x00
aid2 is
0xa0 0x00 0x00 0x00 0x87 0x10 0x04 0xf2 0x30 0xff 0x01 0x89 0x07 0x02 0x00 0x00
When you choose this aid file and look at the fcp file, it is a bit different from the ordinary one

There are more bytes in the middle of the data of Bengal card 0x83 0x02 0xad 0xf1. . . So you can't read aid from inside, you must read from 2F00, it is wrong to write wrong when writing logic.
Another problem is that when the heartbeat data F2, you will need to return the aid data. Is the first aid or the second aid returned?
The test found that Bangladesh used the first aid, indicating that the network application of Bangladesh Card used the data under the first aid.
But the domestic telecommunications card uses the aid behind
