PSD2 / SCA compliance doesn’t have to be another regulatory tick box. Banks should take the opportunity to improve their customers’ experience and most importantly, earn their trust. Our Intelligence-driven authentication can do just that.

Only Callsign's behavioral biometrics are….

Secure and user friendly, behavioral biometrics are the UK’s preferred 2nd factor in a SCA compliance solution. We use advanced behavioral biometrics and device fingerprinting technology to passively authenticate your customers

Behavioral biometrics are compliant with privacy legislation and can be implemented without adding friction to the customer’s experience. Our solution serves all your customers and does not require explicit consent.

Despite the extension for implementing Strong Customer Authentication (SCA) for e-commerce transactions to 14 March 2022, it is expected that issuers go live with a SCA solution as early as possible. Our solution is readily deployable by issuers using either a RSA, VCAS, or Broadcom ACS.

Layered SCA complaint protection

For SCA, behavioral biometric solutions must be able to positively identify the user for inherence to be achieved. Our behavioral biometrics passively analyze traits that another individual wouldn’t be able to replicate, such as keystroke, finger pressure and muscle memory.

What's more, the EBA Opinion issued in June 2019 confirmed the use of swipe authentication (a behavioral authentication method unique to Callsign) as an inherence factor.

Making shopping frictionless,
& secure

Knowledge, possession, inherence

Our unique solution can turn a 1FA login (username/password) into an ultra-secure 3FA journey, with layered location, device and behavioral biometric authentication data – all collected passively in the background.

Callsign is the only vendor in the world that can do all of this with a single SDK.
