Data formats for virtual ATR sequences
Advanced Security SD cards cannot return an ATR sequence. To use an Advanced Security SD card as a smart card with a BlackBerry device, the reader driver constructs a virtual ATR sequence that is based on the CID register of the Advanced Security SD card. The following tables describe the formats for a virtual ATR sequence. Interface characters are not specified in the virtual ATR sequence.
