The app is designed to provide users with valuable information about their contactless chip cards. By utilizing the NFC interface, the app is able to analyze various types of payment cards, including MasterCard, VISA, AMEX, Diners, JCB, and others. This allows users to easily access important details about their cards, such as whether it is a debit, pre-paid, or credit card, as well as the limitations and security functions associated with it.

In addition to providing information about the card itself, the app also offers insights into how these limitations and security functions may impact the user's payment methods. This can be especially helpful for those who are looking to better understand their card's capabilities and make more informed decisions when using it for transactions.

For those who have an USB chip card reader, the app offers the option to connect it to their device and read the contact chip for even more detailed information. This feature can be particularly useful for individuals who want to have a deeper understanding of their card's specifications and capabilities.
