Skimmer Scanner: A Gas Pump Skimmer Detection App by SparkX

A bluetooth based gas pump skimmer

The inside of a bluetooth gas pump skimmer

The Skimmer Scanner is a free, open source app that detects common bluetooth based credit card skimmers predominantly found in gas pumps. The app scans for available bluetooth connections looking for a device with title HC-05. If found, the app will attempt to connect using the default password of 1234. Once connected, the letter 'P' will be sent. If a response of 'M' then there is a very high likelihood there is a skimmer in the bluetooth range of your phone (5 to 15 feet).

The app does not obtain or download data from a given skimmer nor does it report any information to local authorities.

Skimmer Scanner is free, open source, and currently available for Android available here. Please help us make it better! We are not mobile app developers and can use all the help we can get. We very much need an iOS version. Thank you!
