Jerry Jalava has built a special prosthetic finger which contains computer storage for photos, movies and other useful files.
While the prosthetic looks like a normal finger Jerry can peel it back from the 'nail' and plug it into the USB slot on his computer using it as an additional hard drive.
When Jerry told doctors what he did for a living they joked he should have a USB 'finger drive' but that was good enough for him, and he set about making one.
Using a traditional prosthetic finger Jerry has been able embed a 'USB key' - like the ones used in traditional flash drives - giving him the world's only two gigabyte finger.
The finger is not permanently attached to his hand meaning it can be removed when plugged into a computer.
"It is not attached permanently in to my body, it is a removable prosthetic which has USB memorystick inside it," said Jerry.
