Based on the latest patented flash payment interaction technology, the authentication code is transmitted through high-speed flash light that is built into existing mobile phones. This means that instead of relying on QR codes, the payment process is completed with a simple flash. Using mobile phones as a payment option has also lowered the cost of installing and maintaining such technology for businesses compared to NFC technologies.
The tech is user-friendly as customers only need to keep a 15cm distance, point to the payment device, and tap the flash button in the app to complete the payment.
