A mobile communication device has a processor, a radio, a near field communication (NFC) device, a battery, and memory for storing data. The power level of the battery is measured. When the measured power level is above a first predetermined level, power is provided to the radio to allow communication. Sufficient power is provided to operate the NFC device as a reader and a tag. When the measured power level of the battery falls below the first predetermined level, battery power to the radio is shut off. Sufficient power is maintained to the NFC device to allow it to operate only as a tag. Sufficient power is maintained to the memory to retain the data stored in the memory. When the measured power level of the battery falls below a second predetermined level, the NFC device is required to harvest all of its power from the field.

Optimization of NFC tag for different battery levels

Embodiments of the present disclosure describe an apparatus, method, and computer readable medium for processing a secure transaction. One embodiment describes an apparatus comprising: a processor; a secure element coupled to the processor; and a connectivity device coupled to the secure element, and configured to exchange communications with a device that is external to the apparatus, and receive and execute one or more unsolicited commands from the secure element.

Secured multi-directional, multi-interface transaction processing

Apparatus for harvesting and using power in a near field communications mode, includes a host device with operating components. A first near field communication (NFC) device is contained in the host device and is configured to be selectively coupled to one of the operating components. The first NFC device harvests energy from a second NFC device and converts the harvested energy to electrical power. The first NFC device receives information from the second NFC device and power on the operating component as a function of the information received from the second NFC device. The first NFC device transfers data to or from the operating component when the operating component is powered on. The first NFC device powers off the operating component when the transfer of data between the first NFC device and the operating component has been completed.

Power harvesting and use in a near field communications (NFC) device

A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. The NFC device can include a plurality of secure elements each configured to store one or more card emulation instances. Each card emulation instance is associated with an application identification (AID) and a priority value. The NFC device can route communications between another NFC device and plurality of secure elements based on each card emulation instance's associated AID and priority value.

Near field communication application identification routing in card emulation

A system, method, and apparatus for negotiating a communication link between first and second near field communication (NFC) devices is disclosed. A third NFC device is placed in close proximity with a first host device operatively containing the first NFC device to determine communication information including at least one of a communication mechanism and a data transfer protocol usable by the first host device. The communication information usable by the first host device is stored in a portable device operatively containing the third NFC device. The third NFC device is momentarily placed in close proximity with the second NFC device. The stored communication information of the first host device is transferred from the portable device to a second host device operatively containing the second NFC device. A communication link is established between the first and second host devices to enable the first and second host devices to transfer data between them as a function of the determined communication information.
