What are the technical and set up requirements for using the service Google Pay?
Google Pay works on Android mobile devices running Lollipop 5.0+ or higher. The mobile phone must have the NFC technology with an unmodified version of the Android operating system. The client must set up a screen lock on his device.
The options to unlock the screen include: password, pattern, fingerprint, or face scan. If screen lock is not set up, it will not be possible to add a card to Google Pay.
If you remove the screen lock option or in case of any unauthorized modifications made to the operating system used on the device, the cards added to Google Pay will automatically be deactivated and payments using the application will be disabled. The number of cards that can be stored in Google Pay is unlimited. One and the same card can be stored in more than one Google Pay applications on different devices.
