The CEO of SparkFun, Nate Seidle, partnered with programmer Nick Poole to develop a mobile application “Skimmer Scanner.” This free, open-source Android app is built to detect credit card skimmers that are used most popularly in the area around your phone, specifically at a petrol / gas station.

This app uses your phone’s Bluetooth radio to detect a common radio component in modern fuel pump skimmers (HC-05) and warns you if you’re about to get scammed. It attempts to establish a connection, and then verifies if there is, in fact, a skimmer in the vicinity.

Important Note by App The Developers

The effective range of this app varies by phone and by skimmer. For best results, hold your phone close to the gas pump. Also, please keep in mind that failure to detect an HC-05 based device does not guarantee there is no skimmer present. There’s always a risk to sticking your card in a strange machine.

Skimmer Scanner can be Downloaded (free) by the following link for Android Devices:
