«Mastercard unleashes new era of biometric #payments to enhance the checkout experience».
When using #biometric systems please keep in mind one big rule: the biometric data HAVE to be stored on a secure chip/device you own. If the data are store/managed by the service provider the system is insecure and not #privacy compliant by design.
Please avoid those kind of systems: a #databreach is always possible and you will loose something you can't change.
