Deutsche Bank is experimenting with new antifraud technology that uses the way you handle and hold your phone to work out if you are really you.
The bank hopes the system will free customers from passwords and allow it to lift limits on mobile transactions.
The technology analyses about 50 different factors to build a picture of a user from pressure applied to the pin-pad to how the phone is held, location, facial recognition and thumbprint.
Some of these are already in use. MasterCard is trialing facial recognition — dubbed "selfie pay" — and voice recognition.
The boast of Callsign — the company working with Deutsche Bank on the new technology — is that its system brings so many factors together.
