Apple Pay users that store other people's fingerprints on their iPhones might find their terms and conditions agreement voided, banks warned.
The Apple Pay system, launched in the UK in July, uses Apple's Touch ID – the company's fingerprint scanning technology used for unlocking iPhones – to authorise retail transactions.
While iPhone users can store as many as 10 fingerprints on some iPhones – to allow family members to share their devices – these settings could create several unintended consequences.
If mobile bank customers fail to heed these notices, banks may opt not to refund disputed transactions or may not assist customers when they if they become victims of fraud.
Lloyds Bank terms stated, “You must ensure you only register your own fingerprints (and not anyone else's)”. HSBC and First Direct issue similar warnings in the terms and conditions.
