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. |
