I want to read and write data in SLE4442 smart card i have ACR38U-i1 smart card reader
For write I am use this commandAPDU
byte[] cmdApduPutCardUid = new byte[]{(byte)0xFF, (byte)0xD0, (byte)0x40,(byte)0x00, (byte)4,(byte)6,(byte)2,(byte)6,(byte)2};
And for read data
byte[] cmdApduGetCardUid = new byte[]{(byte)0xFF,(byte)0xB0,(byte)0x40,(byte)0x00,(byte)0xFF};
both are execute and send SW= 9000 but no one data receive in responseAPDU Like I write 6262 data but it not receive
I am also use Select command to before write and read command
The select command is
byte[] cmdApduSlcCardUid = new byte[]{(byte)0xFF,(byte)0xA4,(byte)0x00,(byte)0x00,(byte)0x01,(byte)0x06};
Have anyone Proper java code to read and write in SLE4442 smart card ?
回答1:
APDU Commands related to work with Memory Cards could be different for different readers and implemented support. Here is an example for OmniKey reader.
Take a look to your ACR reader specification and use specific Pseudo-APDU command to work with SLE 4442.
For your question:
4.6.1 SELECT_CARD_TYPE: "FF A4 00 00 01 06", where 0x06 in the data meant "Infineon SLE 4432 and SLE 4442".
4.6.2 READ_MEMORY_CARD: "FF B0 00 [Bytes Address] [MEM_L]", where
[Bytes Address]: is the memory address location of memory card[MEM_L]: Length of data to be read from the memory card
4.6.5 WRITE_MEMORY_CARD: "FF D0 00 [Bytes Address] [MEM_L] [Data]"
[Data]: data to be written to the memory card
You used P1 = 0x40 and this could be an issue.
