ATM Skimmer Detector is a free Android application developed by JDebug that helps users detect skimmers installed in ATMs and fuel pumps to steal credit or debit card information. The app uses Bluetooth signals to detect skimmers like HC-05 and warns users if it encounters any such skimmers. The app is compatible with Android 4.4 and can be used to alert friends, property owners, and law enforcement if a skimmer is detected.

To get optimal results, users should keep their phones close to the fuel pump or ATM machine. However, it is essential to note that the application may not detect skimmers correctly, and users should proceed at their own risk. The Disclaimer also states that users should not use the application for any illegal activities and are responsible for any misuse of the application.

Overall, ATM Skimmer Detector is a useful utility application for anyone who wants to protect their Debit/Credit card information while using ATMs or fuel pumps.
