Abstract: The present invention provides a physical card capable of improving authenticity identification and a method of using thereof. The physical card is provided with two electronic tags of different wavebands. When a physical card is to be traded, the purchaser can perform an appearance inspection of the physical card, or use a first reader in the purchaser's mobile phone to directly read a high-frequency electronic tag of the physical card and obtain a card first information, so that purchaser can quickly and automatically determine the authenticity of the physical card. In addition, an UHF electronic tag in the physical card can be read by a second reader of a verification agency, and then a second information of the physical card can be obtained. Since the physical card is used without leaving the holder of the physical card during the whole process, the contactless transaction mode maintains a social safety distance, which can improve the security of the physical card when in use.

Abstract: The present invention provides an identity identification system and method. The identity identification system comprises a first RFID tag, at least one wireless signal sensing device, and a server device. The first RFID tag is an RFID tag capable of long distance communication, disposed on a portable object, and for transmitting a first identification signal. The first identification signal is a wireless signal of long distance, and includes a user identification code. When the portable object carried by a user is through a signal sensing area of the wireless signal sensing device, the wireless signal sensing device will sense the first identification signal and transmit the first identification signal to the server device. The server device determines the user's identity by the identification of the user identification code of the first identification signal, and therefore decides whether a service of picking up goods or paying is executed.
