TECHNIQUES FOR SELECTING A PROXIMITY CARD OF A MOBILE DEVICE FOR ACCESS
First Claim
1. A portable computing device, comprising:
- an antenna;
storage that stores a plurality of identification numbers; and
a processor configured to control modulation of an identification number of the plurality of identification numbers onto a carrier signal received by the antenna from a proximity card reader device.

Abstract
Methods, systems, and computer program products are provided that enable a mobile computing device to emulate multiple proximity cards. A portable computing device may store a plurality of identification numbers. The portable computing device may respond to a proximity card reader interrogation transmitted by a reader device by providing one or more of the stored identification numbers in response. In one implementation, the portable computing device may transmit the stored identification numbers in sequence, one or more times. Alternatively, the portable computing device may select one or more particular stored identification numbers to provide in response, based on a location or other attribute of the portable computing device. An applicable function may be enabled when an identification number provided by the portable computing device is determined as a match by the reader device.
