Tesco have installed cameras in their Cambridge store to take you picture every time you take a packet of Gillette razor blades from the rack, and again when you go to the checkout.

"Still, customers might not infer from this information that these cameras are being used to take a digital photo of them each time they lift a Gillette razorblade from the store's shelf - it only takes one to prompt the camera - and again when they present the pack at the checkout. Tesco says that the photos are "temporarily stored", but does not specify for how long. However, Smart Labels Analyst magazine explains that this system enables the store to "blacklist certain shoppers and keep an eye on them". In his interview with the magazine, Alan Robinson recounts an occasion when his Cambridge store was able to show the police a photograph of a shoplifter in the act of removing two packets of razors from the shelf: "The police were completely flabbergasted, having never seen anything like it in their lives."

Next time you are in you could....

a) take packets from the shelf at least 50-60 times (fill up the digital camera with crap)

b) Do a bit of a Bob Dylan spoof and take some pre written placards to hold up to the camera whilst repeatedly taking packets from the rack. (or just stick them the 'V' sign)

c) take packets from the shelf then ask for all information being held on you under he requirements of the data protection act.
