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.

Re: Change Card Manager AID on JavaCard 3.x

Great spot, thanks. The DGI-formatted command was being generated by the JCOP Tools, so I had assumed it was in the right format!

Re: Change Card Manager AID on JavaCard 3.x

The extra 00 70 bytes in there specify DGI formatting I believe? I have also tried this option, and it fails with a different error:

Code: Select all

=> 80 E2 80 00 0C 00 70 4F 08 A0 00 00 00 03 00 00 00
<= 6A 80
