Description

Technical Field

[0001] The present invention relates to the field of visible light communication, and in particular to a payment method, system, device and medium based on visible light communication. Background Art

[0002] In traditional card reader technology, magnetic cards and IC cards are widely used as information carriers, but they each have significant disadvantages.

[0003] First, magnetic cards record information through magnetic stripes. The data storage capacity of this recording method is very limited and cannot meet the needs of large data storage. What is more serious is that the magnetic stripes are prone to demagnetization after long-term use or improper handling, resulting in the loss or damage of data stored on the magnetic stripes. This instability not only brings inconvenience to users, but also brings potential risks to commercial transactions.

[0004] Secondly, IC cards use radio frequency signals for communication, which improves the efficiency and security of data transmission to a certain extent, but the problem of occupying radio resources cannot be ignored. In addition, IC cards also have electromagnetic compatibility issues when used, which may interfere with other electronic devices, affecting the normal operation of the card reader and the accurate reading of data.

[0005] With the continuous development of technology, card readers equipped with NFC and Bluetooth technologies have appeared on the market. However, these new card readers also have certain application limitations. Although NFC technology has the advantages of high speed, security, and convenience, it has not yet been fully popularized. Currently, only some high-end smartphones on the market are equipped with NFC modules, which limits the application of NFC card readers in a wider range of fields. Although Bluetooth card reader technology can achieve wireless connection and data transmission, it requires a cumbersome authentication and connection process each time it is used, which lacks convenience.
