      Secure, reliable and scalable

      PDQ powered by Sera4

      A special shaped object has granted access rights to the holder for centuries. Metal keys are still used everywhere. They do their job, but they are limited. They don’t know who carries them. They have to be physically handed to someone to pass on that access right. Or, collected to revoke it. They are often misplaced or stolen.

      It’s time to move forward. We all carry smartphones. We trust computer networks to safely represent and move our money. We no longer need to carry a special object like a key, a fob or a card to get access to the most secure places.
