Datablink Mobile 200 is an innovative mobile app that offers advanced authentication and financial transaction signing for users and their banks enabling the prevention of unauthorized access and fraudulent transactions. Rather than requiring a user to physically type a code into a device to generate a one-time password, users simply use their smartphone to confirm their identities. No other devices are required. To verify a user’s identity or sign a specific transaction, the organization can choose to employ push technology or use a QR Code that is read by the user’s smartphone camera.
