technical field

The invention relates to a wireless radio frequency sensing system, especially a radio frequency sensing system with interactive functions. Apps built into the device are used.

Background technique

Radio Frequency Identification (RFID) and Near Field Communication (NFC) are common radio frequency sensing technologies today. Among them, Radio Frequency Identification includes three types: passive, semi-passive and active. Near Field Communication is based on Developed based on radio frequency identification technology, it is divided into two types: active type and passive type. In radio frequency identification and near field communication technology, passive type is more widely used.

Please refer to Fig. 6, the existing radio frequency sensing system mainly includes an electronic tag 70, a card reading device 80 and an application service device 90, and the electronic tag 70 includes a radio frequency communication controller 71 (RFID technology then uses RFID operation controller, NFC technology then uses NFC operation controller), a transceiver antenna 72 and an encoder 73, and the radio frequency communication controller 71 is electrically connected with the transceiver antenna 72 and the encoder 73, the encoder 73 A set of digital information (usually a set of codes) is stored; the card reading device 80 is connected to the application service device 90 and continuously emits an electromagnetic wave. When the electronic tag 70 approaches the card reading device, the electromagnetic wave will be in the electronic The sensing current is generated on the transceiver antenna 72 of the tag 70 to drive the radio frequency communication controller 71, so that the radio frequency communication controller 71 reads the digital information in the encoder 73, and makes the transceiver antenna 72 output according to the digital information A radio frequency signal is sent to the card reading device 80 , so that the card reading device 80 interprets the digital information and outputs it to the application service device 90 .

In commercial applications of the above-mentioned radio frequency identification technology and near field communication technology, the electronic tag 70 will be set on a carrier, such as a card, to make a membership card, a security card, a stored value card, etc., and the user can hold the When various cards approach the card reading device 80, actions such as confirming membership status with the application service device 90, canceling or setting security, and storing value can be completed.

It can be seen from the above wireless radio frequency sensing system that the stored information of the electronic tag can only be read by the card reader near the card reader. For payment applications, the user is limited to know the stored amount only through the card reader. You have to wait until the card reading device shows that the amount is insufficient to know that you need to store value; just because the current electronic tag memory information is closed to the user end, the current inconvenience still exists.

Furthermore, since the client only holds a card with an electronic tag, and the card reader is the only electronic device that can establish a connection between the electronic tag and the application service device, the user can only transmit information to the application service device in one direction. Service providers cannot establish Internet interactive relationships with users; for example, operators cannot provide multimedia advertisements or digital information, and users cannot use electronic tags to complete authentication through Internet programs and application service devices.

To sum up, the existing radio frequency sensing system is inconvenient for users, and the server of the above radio frequency sensing system cannot interact with the client, and cannot meet the needs of the service provider and the client. Therefore, it is necessary to Improved.
