Instead, it'll be limited to gas pump inspectors, presumably in part because the university teams created it with technical input from the US Secret Service.The Bluetooth pump skimmer scanner app ‘Bluetana’ in action. Unfortunately for consumers wary of potential card fraud, the app won't be released for general use. Bluetana typically takes three seconds to detect a skimmer, versus 30 minutes on average for physical searches. That includes two skimmers that had been gathering credit and debit card details for six months without being spotted. "In a few cases, our app was able to find devices missed by visual inspection."Ī public trial in three US states has seen 42 skimmers identified by inspectors using the app overt the past year. ![]() "Bluetana extracts more meaningful data from the Bluetooth protocol, such as signal strength, than existing skimmer detection applications," Maxwell Bland, coauthor of a study on the new app, explains. By analyzing scans of found Bluetooth skimmers, the researchers came up with an algorithm that can better differentiate between the skimmers' wireless fingerprint and Bluetooth in use by other devices nearby. ![]()
