Patent Images
1. A mobile device, comprising:
- a battery;
a short-range wireless (SRW) communication chip set;
a secure element incorporated into the battery; and
an activation switch at an outer surface of the battery, wherein the activation switch is configured to disconnect the secure element when a user physically actuates the activation switch at the outer surface of the battery;
wherein the SRW chip set is configured to sense proximity to a point of sales terminal and, in response, initiate bootup of the mobile device, and power up only the SRW chip set and the secure element.
