How I Hacked Hospital RFID

A flaw in my local hospital security meant I could open doors I was not supposed to: My father was ill in our local general hospital. This was bad enough but all the stress of someone being in a UK hospital is compounded by the nightmare which is NHS parking.

Just as well no-one who goes to a hospital is infirm, or needs to get there urgently.
