Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

What is Multi-records Reading APDU command structure?

Post by leonard » Thu Dec 10, 2015 10:53 pm

I have a card support T0 protocol with an applet is installed on it. The host send a "multi-records reading" command to get records data. Records are read which are specified by record identifiers in this data field of this command. These are steps that I did:
1. Select DF
2. Send a command to read sequence of records[/list]

Code: Select all

00 B2 00 06 16 73 0A 51 02 40 01 54 04 00 10 00 04 73 08 51 02 40 02 54 02 00 01 00

The meaning of the command is as bellow:
- INS = 'B2': read record(s)
- P1 = '00': references the current record (ISO 7814-4, 7.3.3, table 48)
- P2 = '06' = '00000 110' :
'0000' indicate current short EF id (ISO 7814-4, 7.3.2, table 47)
'110' mean read all records from the last up to P1 (ISO 7814-4, 7.3.3, table 49)
- Le = 16 : data length
Data field follow the BER-TLV, for example:73 0A 51 02 40 01 54 04 00 10 00 04
Tag'73' indicate that sequence of bytes above consist hierarchy data object structure in data filed (length = '0A')
Tag'51' reference to 2-byte EF identifier = '40 01'
Tag'54' reference to one or more record identifiers, in this case are '00 10' and '00 04'

- Le = '00'

This is expect respond from card:
53 |length of data| record data| 53| length of data| record data|......


I test this command with the card, the card return 'Unknown Error' message.
Could you tell me what is wrong with the command? What is correct multi-records reading command?
Thanks.
