You would need a fairly, powerful EM (electromagentic) source to fry the thing which aren't too easy to get access to. It probably wouldn't be too clever if you wearing it as well.

      Interestingly though i doubt many RFID tags would stand up to a hot wash, plenty of water with detergent and a big motor as an EM source nearby driving it might well fry it... Dunno the thought just occured to me - anyone got any ideas how physically tough the chips are?

    • Personal information can only be collected with your approval (or if mandated by a law)
    • This information can only be gathered for specific purposes (of which you must be informed) and may only stored for a set period of time, which can not be unreasonably long.
    • You can request access to the information about you and request correction or deletion
    • Your info must be kept confidental and correct
    • Your personal information can be given to a third party only if the above requirements are fulfilled

They record exactly what came in on a form and turn it in to the office staff who enter the information into the database. This relies on the warehouseman to count the material correctly, fill out the form correctly, then for the office staff to enter the data correctly. The system works, but there are many opportunities for data entry errors. One misread, miscount, mis-type and the data is bad. 2. Material arrives at the dock and barcodes are scanned. The data is uploaded to the system without any human interaction besides the original scan and a later check against the Bill of Lading that came with the load. Much better than the first method, but it comes with its own issues. For one, if the material is put into location, stacked high off the ground, reading barcodes for inventory purposes can be problematic. Also, it relies on a good quality barcode. A lot of our material arrives after long truck/train rides with the material rubbing and jostling against its neighbor resulting in many unreadable barcodes. RFID is the next logical step for us. For the material to cross from the truck/train to our dock and be read by an RFID reader without the warehouseman having to aim a laser at a possibly unreadable barcode would be nice. The customer would also be able to follow that particular RFID all the way from manufacturing through the distribution process.
