ATM Card Checker is a free application developed by Genius App Developing that allows users to validate the credit and debit card by using the Luhn algorithm. It checks the card's length, prefix, and checksum to ensure that the entered card number is valid. This app helps users to identify the card issuer or network associated with the entered card number, which can be helpful in verifying the legitimacy of the card. The application also includes a BIN checker that can check the first 6 digits of the credit card number to reveal the card's country, type, and bank info.

The app has several features like saving the debit and credit card, saving bank account details, calculating credit score, and getting IFSC code of any bank. It is designed to check the existence of a Bank Identification Number (BIN) based on an updated database of over 400,000 unique BIN. The app is easy to use, and the results are displayed in no time. The user can check whether their card is working or not, and the most important advantage is that the app is free to use.
