Credit Card Checker app analytics for May 1

Having trouble using your credit card in certain countries? Or does your card not work in remote places? This app helps you to understand what data is stored on the NFC chip of the Credit card. The app analyzes your contactless chip via the NFC interface and provides you with some useful information about your card. It works with MasterCard, VISA, AMEX, Diners, JCB and some other payment cards. You can find out whether you have a debit, pre-paid or credit card, which limitations (CVM, online/offline etc.) and security functions are supported by your card and how this affects the payment methods. If you have an USB chip card reader, you are also able to connect this to your device and read the contact chip to reveal further details. You may also verify your PIN. For privacy reasons this app does not have any internet connection, ads or other stuff. Processing of your credit card data is done purely on your device.
