• in response to detecting the manipulation of the physical control:
• accessing the memory of the physical card device and activating the selected first account stored in the memory;
• and
• rendering on a display device a visual representation of the activated first account;
• reading from the memory a first account number associated with the activated first account;
• and
• providing a first account number of the activated first account.
