RFID Tags on Mach3 Razorblades Snap Your Photo

peteo writes "Think RFID tags are harmless? Look at how they are being used in the UK: "At the Tesco Cambridge store, a camera trained on the Gillette blade shelf, and triggered by RFID tags, captures a photo of each customer who removes a Mach3 pack. Another photo is taken at the checkout and security staff compare the two images to ensure they always have a pair" According to the spokesman,"there are certainly not any privacy concerns" in relation to these tags. He adds that there is plenty of in-store signage indicating the supermarket's use of CCTV cameras. ""
