Welcome to our FAQ
I have several cards, from different manufacturers. How can I differentiate them? How can I retrieve their characteristics?
Why the card’s ATR is different from a product to another one or from a firmware version to another one?
Please visit the blog of our R&D Team: it contains a lot of additional information.
