1. A portable computing device, comprising:
- an antenna;
storage that stores an identification number; and
a processor configured to control modulation of the identification number onto an unmodulated carrier signal received by the antenna from a proximity card reader device to enable the portable computing device to emulate a proximity card;
wherein the portable computing device is configured to emulate a proximity card by responding to the proximity card reader device in a first mode using the antenna, and to receive a wireless charging signal from a wireless charger using the antenna to charge a rechargeable battery in a second mode, the processor enabling the identification number to be modulated onto the unmodulated carrier signal for a predetermined time duration, and causing the portable computing device to enter the second mode after expiration of the predetermined time duration to wirelessly charge the rechargeable battery.

Abstract
Methods, systems, and computer program products are provided that enable a portable computing device to emulate a proximity card. A portable computing device is provided that includes an antenna, storage that stores an identification number, and a processor. The processor is configured to control modulation of the identification number onto a carrier signal received by the antenna from a proximity card reader device. In this manner, an applicable function may be enabled, and the portable computing device emulates a proximity card. The antenna may be specific to proximity card emulation, or may be shared with other portable computing device functions, such as wireless charging.

19. A computer readable storage medium having computer program instructions stored in the computer readable storage medium that enable a processor to perform a method in a portable computing device, the method comprising:
-
accessing an identification number stored in storage of the portable computing device; receiving an indication of an unmodulated carrier signal received at an antenna of the portable computing device from a proximity card reader device; disabling wireless charging capability associated with the antenna to operate in a first mode; providing the identification number to a modulation circuit of the portable computing device according to predetermined timing for a predetermined time duration to modulate the identification number onto the unmodulated carrier signal by the antenna to enable the portable computing device to emulate a proximity card; and enabling wireless charging capability associated with the antenna to operate in a second mode after expiration of the predetermined time duration. - View Dependent Claims (20)
