The first QR code generated on the smartphone will be scanned by the POS terminal, the terminal will generate a BLE signal to communicate to the smartphone, and lastly, a second QR code will be generated on the smartphone and scanned by the terminal to complete the transaction.
It looks simple, but there is still a lot of work we have spent on the BLE development to make sure there is no communication compatibility problem.
