Keyra Card

Your bank already puts a secure computer in every customer’s pocket.

Now give it another job.

Keyra is firmware-level trust infrastructure for the card your bank already issues. It adds hardware-rooted identity, authentication, verification, authorization and access capabilities alongside the existing payment application.

One card. Two jobs. Payment + Trust.

Keyra is firmware for the card your bank already issues.

Positioning

  • It’s not another app.
  • It’s not another token.
  • It’s firmware.

Keyra lives inside the card.

A Keyra trust application operates inside a compatible card’s secure element alongside the existing payment application.

The card is already a computer. Keyra gives that computer another job.

Inside the card

Open the card.

The card already contains contact interfaces, antenna, microprocessor and secure element. Keyra adds a second application domain—without replacing payment.
