A device for contactless communication with a terminal, the device comprising: an antenna for receiving a wireless signal emitted by the terminal; an embedded chip configured to generate data for communication to the terminal to perform a first function associated with the device; and a module separate from the chip configured to perform processes as part of a second function associated with the device, the module being connected to the antenna and comprising a power-harvesting unit configured to harvest power from the received wireless signal to power at least the module.

A radio frequency identification (RFID) system first interrogates, in a first mode, one or more particular target zones of the plurality of target zones including a given target zone. Each particular target zone is interrogated with one of the antennas at a time at a first power for the particular target zone. The RFID system monitors, upon first interrogating, for a trigger condition to occur. In response to the trigger condition not occurring, the RFID system continues the first interrogation in the first mode. In response to the trigger condition occurring, the RFID system second interrogates the given target zone in a second mode at a second power with a plurality of the antennas. The second power for the given target zone is greater in an aggregate across the second interrogating antennas than the first power for the given target zone.

The present invention relates to a wireless power transmitter and method for detecting a RFID/NFC card. Disclosed in the present application is a wireless power receiver comprising: a power pickup unit configured to receive, in a power transfer phase, wireless power generated by magnetic coupling from a wireless power transmitter; and a communications/control unit configured to transfer, in a negotiation phase, a first end-of-power-transfer (EPT) packet to the wireless power transmitter for detecting an RFID/NFC card, and to detect the RFID/NFC card during a re-ping time secured on the basis of the first EPT packet, wherein the first EPT packet instructs requesting the removal of a power signal for a predetermined time. As the process for detecting communication cards, such as RFID or NFC, between the wireless power transmitter and receiver is clearly defined, such RFID/NFC cards can be protected against getting destroyed by the wireless power, and a stable wireless power transfer can be achieved.
