Samsung Galaxy S5 to read your fingerprints
The sensor will apparently work with a vertical swipe of the pad, while you keep your finger flat and at a medium swipe speed.
Basically, it is the same as the iPhone 5S from Apple.
S5-havers will be able to register their own fingerprint, as well as seven other prints (you could try a dog's nose or your nipple) and assign them to various app shortcuts or other tasks. There will be the usual PIN code if you don't like the idea of using your fingerprints or, indeed, don't have fingers.
Reports have said that Samsung are also looking at iris-scanning security technology, and execs at the company have confessed that they're looking into it, but alas, it won't be appearing on the Galaxy S5.
