We have extensive experience in information security systems and controlling access to IT resources (common card), for example, within the public key infrastructure. Our cards can be equipped with a proximity part operating in the most popular standards on the market, namely Mifare, Unique, and Legic. As a result, our CryptoCard Graphite card also becomes an indispensable product for securing access to premises (hybrid card). This brings a significant advantage of having only one card fulfilling two key roles in the company.
