Computop, a Germany based payments processor, announced an authentication service called Biometrics by Computop, which is designed to help online merchants and banks operate in compliance with the new PSD2 authentication rules that are scheduled to go into effect across Europe by mid-September. 

Computop's new biometrics service allows merchants to apply authentication early on in the process when customers are logging onto an app or online store, or during the checkout process, according to a company release. 

After the authentication steps are taken, Computop generates a digital signature that can be sent to issuers.

"What we are providing with Computop Biometrics is a host of great advantages for retailers," Ralf Gladis, CEO of Computop, said in the release. "Biometric authentication can be applied to app or shop logins in order to avoid fraudulent account takeovers."
