Want to find a nifty use for the fingerprint sensor on the Pantech Vega LTE-A? Well, thanks to the hard work of two South Korean companies, it’s picking up the ability to pay for goods by authenticating with your fingerprint. This news comes from Danal, a mobile payment provider, which tapped the fingerprint technologies of Crucialtec to create the BarTong app. While the concept of fingerprint-based payments isn’t entirely new, it’s claimed to be an industry first for the mobile phone. The BarTong app is currently exclusive to South Korea, but its creator is looking to expand the payment service into the US and China. Naturally, Danal may want to hold off until fingerprint readers become more widespread in smartphones, but we certainly won’t fault the company for being ambitious.
