Cardless Atm Transactions With Security System Using Visible Light Communication

Abstract The physical card is replaced with a LiFi module with a real-time integrated finger-vein recognition system for automated teller machine authentication. The technology, which is based on an integrated LiFi platform, includes a sophisticated algorithm for detecting finger veins. There are three hardware components in the suggested system: an image-capturing module, an embedded main board, and a human-machine communication module. According to the system's structural design, finger-vein images are captured using the image acquisition module. On the embedded main board, which also includes a communication port and a microcontroller chip, the finger-vein identification mechanism is implemented. Results of recognition are displayed and user input is taken in by the human-machine communication module. The LiFi module is used to deliver the user's data instead of the card. The vein will be scanned by the ATM. The transaction can be successfully completed if the finger veins match. If the vein doesn't match, it will use GSM technology to deliver the OTP message to the authorized user.
