RFID-based information read-write method, device and equipment and storage medium

Abstract

The embodiment of the invention provides an RFID-based information read-write method, device and equipment and a storage medium. The method comprises the following steps that when a calling request ofan application is received, a main data value of a main storage area recorded in an RFID tag and a standby data value of a standby storage area recorded in the RFID tag are read; the main storage area and the standby storage area are two independent storage areas in the RFID tag, and the main data value and the standby data value are written in sequence in a serial mode; when the main data valueand the standby data value are different, the main data value and the standby data value with a preset reasonable interval are compared to obtain a comparison result; and a correct data value is returned to the application initiating the data call according to the comparison result, and the RFID tag is rewritten according to the correct data value. According to the invention, the backup protectionof the written information is realized, and the normal identification and use of the application are ensured.

Description

technical field [0001] The present invention relates to the field of RFID technology, in particular to an RFID-based information reading and writing method, device, equipment and storage medium. Background technique [0002] RFID technology is an important non-contact automatic identification technology. It uses radio frequency signals to achieve non-contact two-way data communication through spatial coupling (alternating magnetic field or electromagnetic field), and achieves the purpose of identification through the transmitted information. As an anti-counterfeiting technology, RFID radio frequency tags have been widely used in various industries. Among them, some applications only need to simply read the information on the card for identification, while some applications need to write some information during use, such as bus cards, recharge cards for shopping malls, or anti-counterfeiting labels. However, it takes a certain amount of time to write information to the RFID...

Problems solved by technology

However, it takes a certain amount of time to write information to the RFID tag. The specific time depends on the implementation of the memory. If abnormal conditions such as power failure occur during the writing process, the written information will be wrong, so that the When reading this information, the information obtained is lost or abnormal, and illegal values ​​are obtained, which in turn affects the identification and use of applications
