Yapital, a European cross-channel payment solution, is presently testing payment by fingerprint scan, which could replace PIN entry when paying by smartphone.

Yapital innovations senior vice president Oliver Kress said, "As the major smartphone manufacturers are now integrating fingerprint scanning into their products, we have immediately launched appropriate tests."

"The aim is to discover whether new technologies meet the demands that Yapital places on usability and securit," Kress added.

The company said that the payment process by fingerprint would be the third major innovation by the cross-channel payment solution this year.

Yapital has already launched the integration of Bluetooth Low Energy (BLE), as well as purchasing by scanning a QR code directly from advertising spaces.
