What can I do if my finger is too dry or too cold?

The fingerprint scanner only works correctly and reliably with the papillary ridges of the front finger joint. If your finger is too dry or too cold, these papillary ridges cannot be sufficiently detected. Try the following:

• You can warm up a cold finger by rubbing it.
• For dry skin, it often helps to rub your finger across your forehead.
• If possible, use a different finger.
