Mobile transaction authentication signature (mTAS) in a smartphone

PayConfirm is a software platform that performs mobile transaction authentication signature (mTAS) to authenticate or confirm any type of operations, including transactions or e-documents, on a mobile device.

Our solution provides clients with a high level of security and an easy way to protect their payments, generated via any digital channels, such as Internet banking, mobile banking, CNP operations, private banking.

No more scratch-cards, USB-tokens, OTP-generators or any other hardware solutions are needed. There is no dependency on mobile operator service and SMS delivery time.

Unlike OTP, mTAS created with PayConfirm is bound to the payment’s details and user’s smartphone. This solution offers protection from the most common security threats in digital banking such as SIM swap fraud, phishing, bank account details replacement and other security threats. Our technology is already successfully adopted and used by more than 60 banks worldwide.
