That fingerprint reader that came with your Samsung Galaxy gadget can secure your lockscreen, but unlocking your device isn't the only task it can help speed up. For heavy PayPal users, it can be an ideal way to make online purchases more quickly. Instead of keying in your PayPal credentials, you can apply your print. Now this ability has come to the Play Store version of the app.
To take advantage of the functionality, you need a Galaxy phone or tablet with a fingerprint reader such as S5, Note 4, Alpha, or Tab S.
