Problems solved by technology
At present, when RFID is used for data transmission, the card with the RFID tag function does not have information that can display the data exchange in the card, so that the holder cannot know and control the received and transmitted information from the RFID tag card held. For example, the e-wallet with RFID tag function cannot know the amount deducted by the current exchange and the balance in the card when conducting transactions, and users cannot effectively control the information in the e-wallet

Embodiment Construction
[0030] Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a first embodiment of a card with a radio frequency identification tag of the present invention. The card 100 with the radio frequency identification tag in this embodiment is used to receive the first radio wave signal with the first information sent by the radio frequency identification reader 200, and after responding to the first radio wave signal, return the radio signal with the second The second radio wave signal of the information is sent to the RFID reader 200 . The card 100 includes: a coil 21 , a micro-processing chip 22 and a switch 23 . The coil 21 is disposed in the card 100 for inducing a first radio signal to form a first signal current with first information. The micro-processing chip 22 is arranged in the card 100 and is electrically connected to the coil 21. The micro-processing chip 22 is used to analyze the first signal current transmitted by the coil 21, so as to generate a second signal cu...

The invention discloses a card with a radio frequency identification tag. The card is used for receiving a first electrical wave signal which contains first information and is sent by a radio frequency identification reader, and sends back a second electronic signal with second information to the radio frequency identification reader after responding to the first electrical wave signal. The card comprises a coil, a microprocessing chip, a switch and a display. The microprocessing chip is arranged in the card and electrically connected with the coil; the switch is arranged between the coil andthe microprocessing chip; and the display is controlled by the microprocessing chip to display the first information or the second information. The switch controls start of the radio frequency identification tag and the display displays the transmitted or received information, thus achieving data anti-stealing and effectively controlling the traveling information.
Description
technical field [0001] The invention relates to a card with a radio frequency identification tag, especially a card capable of displaying information and having a hardware switch to control the function of the radio frequency identification tag. Background technique [0002] Radio Frequency Identification (RFID) is a chip with built-in radio technology. The chip can also record a series of information, such as product category, location, date, etc. The biggest advantage is that it can improve the efficiency of item management. Most of the information is recorded on the barcode, and then the barcode is scanned by a scanner to obtain the information, while RFID only needs to be sensed within a certain range, and can read a large amount of information at one time. RFID technology can be applied to access control, joint tickets, transportation, etc. [0003] The composition of the RFID system mainly includes a tag (Tag), a reader (Reader), and a computer host. The tag is a dat...
