Eyetek's badge camera recorder takes a symbol of optimism and transforms it into a way to spy on others around you.
The "Smiley Face Pin Badge" has a hidden, internal recorder which is able to record both video and audio footage. Equipped with a micro USB port, the badge's data can either be transferred via a USB port or by removing the Micro SD card from the product. Powered by a lithium-ion battery, the pin badge recorder is able to record at a rate of 30 frames per second.
Each badge is priced at £65 ($104).
