The first instance 122-1 may provide first card data (DAT_1) to the ASIC 110 in response to the transaction command.

Depending on the embodiment, ASIC 110 may not store the first AID (AID_1) in a separate storage. In this case, the UMA 123 can respond to transaction commands while separately managing the activation area through the list. A detailed description of this is provided later with reference to FIG. 10 .
