Problems solved by technology
However, there are some problems in the reading and writing operation method in the prior art, for example, if the radio frequency card leaves the radio frequency field within the detectable range of the non-contact card reader, or the operation command sent by the host computer is wrong, it will cause damage to the radio frequency card operation. Failed to detect whether the RF card is in the RF field in real time

Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] figure 1 The schematic flow chart of the radio frequency card reading and writing operation method that an embodiment of the present invention provides, as figure 1 As shown, a radio frequency card reading and writing operation method provided in this embodiment includes:
[0028] Step 101: The non-contact card reader detects whether there is a radio frequency card in the radio frequency field. When there is a radio frequency card in the radio frequency field, the non-contact card reader obtains and stores valid card number information of the radio frequency card.
[0029] The radio frequency card is close to the surface of the non-contact card reader at a certain distance such as 5-10mm, and the data read and write operation between the radio frequency card and the card reader is completed through the transmission of radio waves between the radio fre...

The invention discloses a radio frequency card read-write operation method which comprises: step 101, a non-contact type card reader detects whether a radio frequency card exists in a radio frequency field, and when the radio frequency card exists in the radio frequency field, the non-contact type card reader obtains and stores effective card number information on the radio frequency card; step 102, the non-contact type card reader judges whether operation instructions transmitted by an upper computer are received and judges the type of the operation instructions if the operation instructions transmitted by the upper computer are received; step 103, when the operation instructions are card operation instructions, the radio frequency card is verified within the first preset time range according to secret keys and the effective card number information stored by the non-contact type card reader; and step 104, if secret key verification is passed, the non-contact type card reader performs corresponding operations on the radio frequency card according to the card operation instructions. By means of the radio frequency card read-write operation method, real-time detection on whether the radio frequency card is in the field state can be achieved.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a radio frequency card reading and writing operation method. Background technique [0002] Contactless card, also known as radio frequency card, consists of IC chip and induction antenna, packaged in a standard PVC radio frequency card, IC chip and induction antenna have no exposed parts. Contactless card is a new technology developed in the world in recent years. It successfully combines radio frequency identification technology and IC card reader technology to end the problem of passive and contact-free. It is a new technology in the field of electronic devices. a major breakthrough. [0003] The data reading and writing operation method of the radio frequency card in the prior art is: put the radio frequency card into the radio frequency field of the card reader, after the non-contact card reader successfully finds the card, wait for the upper computer to read an...
