What is the BLE function?

BLE stands for Bluetooth Low Energy. This technology, like NFC (Near Field Communication), serves to establish communication between two compatible devices located within a short distance of each other (maximum 10 cm).  

For the vast majority of iPhones, Seamless validation is done using NFC. This concerns iPhone 7 or higher, with an iOS version 13 or higher.

For older iPhones that do not meet these criteria, BLE technology is used for Seamless validation.
