A computer programmer who lost half his finger after his motorbike crashed into a deer has had the finger replaced with a USB drive.

Jerry Jalava, from Finland, says the two-gigabyte prosthetic finger is not permanently attached to his hand, allowing him to leave his finger in the computer slot and "pick it up after I'm ready".

The silicon prosthetic looks like a normal finger, but can be peeled back at the tip to reveal the USB drive.
