OCRA OTP Cards

OTP tokens that fit in your purse.

The card has a 6-digit LC-Display and a 13-button touch keypad. The card is provisioned with a random and unique secret-key.

Each button is coated with transparent embossing to ensure easy input. The battery will power the card for up to 3 years or about 3000 cycles.

After activation, the display requests a 8-digit challenge and a 4-digit PIN. The card responds with a 6-digit response that is displayed for 10 seconds. The internal memory contains a 8-bit counter that is increased each time a response is presented.

A protective cover and a printout of the secret-key is packaged with the card.

The card is sized in the commonly used ISO/IEC 7810 ID-1 format (85.60 × 53.98 mm).
