Pretec's new i-Disk flash drive is 25 per cent smaller than a quarter, and can store up to 1GB of data. A combination of USB flashdisk and RFID technology in a waterproof case, the i-Disk is made using a semiconductor MCP process, and measures 45.7 x 12.2 x 2.2mm. It will primarily be marketed for use in hospitals, airports and warehouses and production is expected to start in the next few months. Honestly, I don't see much use to a whole gigabyte in a RFID tag other than hiding secret space station plans inside short legged droids. If you have any ideas, please write them after the jump.
