About us

Ayoy was founded in 2010 for the purpose of gathering the cream of the Swedish digital identity and smart card consultancy crop under one roof.

Our customers are mainly producers, suppliers or consumers of digital identities and smart cards.


Our product portfolio is designed to complement our consultancy services in order to enable even greater possibilities for cost savings and increased quality by automating time consuming and repetitive tasks.

Card Verifier is an automated smart card quality assurance tool.

If you are a producer or supplier of smart cards, Card Verifier will help you cut delivery times and increase quality by automating otherwise potentially time consuming quality assurance processes. Automating the quality assurance process also helps ensure that it can be repeated after every change, no matter how trivial it may appear.

If you are a consumer of smart cards, Card Verifier will help you establish a quality baseline for your smart cards that can then be used to continuously validate the cards you order, so that you can be certain that they will work with your applications in your environment, which will help reduce the time needed for your acceptance test processes.

Card Verifier will also allow you to validate not only new cards from the same supplier, but also new cards from potential new suppliers as the need arises.


The services we provide are focused on our areas of expertise. They cover both specific implementations like the Swedish citizen identity cards and healthcare cards, as well as the more general technologies of smart cards, cryptography and digital identities.

  • Smart Cards and Citizen Identity Cards
  • IT Security Audits
  • Product and Service Development
  • Training
