How Does It Work

DIGIPASS 281 supports three native applications: a one-time password (OTP), a challenge/ response and an e-signature application. With a simple push on the button, DIGIPASS 281 generates strong dynamic passwords that can only be used once and have a limited validity.

The e-signature applications require data field validation in order to generate an e-signature. For regular transactions typically the amount will need to be validated in order to complete the transaction signature. For higher risk transactions, banks and other organizations can require an additional validation besides the amount such as an account number. E-signatures are an adequate protection against man-in-the-middle and similar fraud schemes.

Simple Integration

The integration of DIGIPASS 281 into an existing network or application is simple and swift. The authentication device does not require any additional investments in hardware or infrastructure. DIGIPASS 281 is fully interoperable with all members of the DIGIPASS family and works seamlessly with VASCO’s VACMAN and IDENTIKEY Authentication Server products.

Easy To Deploy

DIGIPASS 281 is extremely well suited for mass-deployments. Thanks to its slim design, DIGIPASS 281 complies with standard postal regulations across several countries ensuring a swift and simple distribution.

Different Customization Options

DIGIPASS 281 is fully customizable; it can carry your corporate logo, branding and custom colors, resulting in higher brand recognition for the end user. The customizable artwork on the card allows banks and other organizations to differentiate themselves from their competitors and gain a competitive edge.

Additionally, banks can choose to customize the authentication device with an EMV chip or magnetic strip encoding, in order to turn the authentication device into a regular debit, credit or ATM card.
