7.5 Micron Thick RFID Tag
YesSir writes "The EETimes is reporting that Hitachi has a breakthrough in RFID technology that they are planning to show at this years ISSCC (International Solid-State Circuits Conference). The new RFID chip is their newest mu-chip that, measuring in at 7.5 microns, is ten or more times thinner than a sheet of paper and comes complete with 128-bit identifying goodness."
It is impossible to be "ten or more times thinner" than something else. Now the width of the new RFID can be "one-tenth that of a sheet of paper," but grammatically speaking, something can only be 'n' times larger/longer/heavier etc.
