Dr Mark Gasson, a cybernetics expert at the University of Reading, has become the first human to be infected with a computer virus.
Gasson has had a computer chip implanted in his hand which is programmed to open security doors to his lab. The chip also ensures that only he is able to switch on and use his mobile phone.
But the British boffin deliberately infected the chip with a computer virus. It was then automatically transmitted to affect to the lab security system.
"Once the system is infected, anybody accessing the building with their passcard would be infected too," he told Sky News.
The virus on his chip is benign.
But malicious computer code could give criminals access to a building.
