DIGIPASS 840 Comfort Voice is a user-friendly solution for people with disabilities that combines VASCO Class 1 stand-alone smart card reader functions such as e-signature with EMV-CAP (Europay-Mastercard-Visa Chip Authentication Program) compliance. DIGIPASS 840 Comfort Voice satisfies the Disability Discrimination Act and the APACS standard.

Proven solution for people with disabilities

DIGIPASS 840 Comfort Voice is designed to address the needs of the elderly and those with various disabilities, including visual limitations.

DIGIPASS 840 Comfort Voice is a desktop-size reader with large keys and an oversize high contrast display to make reading and data input easy. An internal speaker and optional headphone provide the following functions:

  • Voice based user interface
  • Voice based signature and one-time password
  • Acoustic feedback on PIN, reference, challenge and amount fields.

The vertical card insert feature is extremely user-friendly and makes secure two-factor authentication possible for everyone.

Factory to Field

DIGIPASS 840 Comfort Voice initializes itself and becomes a personlized device from the moment when a user inserts his smart card and enters his PIN. All secrets are permanently erased when the card is removed.

DIGIPASS 840 Comfort Voice is platform-independent and only requires voice message personalization prior to customer delivery; each reader is identical. Therefore production and distribution are efficient and very cost-effective.

EMV CAP Compliant

Cardholders simply insert their standard EMV chip card into DIGIPASS 840 Comfort Voice and type their PIN for two-factor authentication (something they know, something they have.) Each time a user enters their PIN, a one-time password (OTP) is generated, displayed and announced.

The user can type this secure password to become authenticated over the bank’s network. This dynamic password cannot be used more than once and can only be verified by the issuing bank. The verification of the OTP demonstrates the cardholder’s identity and allows access to the network from any terminal on any platform.

DIGIPASS 840 Comfort Voice can be used in conjunction with VASCO's VACMAN Controller authentication platform. For electronic payments, DIGIPASS 840 Comfort Voice can also be integrated into the 3D-Secure architecture, allowing the cardholder to sign specific account data to complete the transaction.

The reader does not require a connection to the terminal or PC, nor any client software or drivers.

DIGIPASS 840 Comfort Voice may be deployed simultaneously with other VASCO readers sharing the same application.
