About

About EMV Stack

EMV Stack builds free tools and writes clear guides for people who work with chip card payments: terminal and kernel developers, testers, payment product teams and anyone learning how EMV transactions work.

Our tools run entirely in your browser. We do not receive or store anything you paste into them.

Who is behind EMV Stack

EMV Stack is a Switstack project. Switstack builds and runs the site, its tools and its articles.

How our content is made

Some parts of the content on this website are produced with the help of an AI assistant.

All articles and guidance are here to nurture a discussion, develop business relationships and promote good practices in the space of EMV payments. They are not official specifications or professional advice: always check the EMVCo and payment scheme documents that apply to your project.

If you spot a mistake or want a tool we have not built yet, tell us through Support.
