Hahaha. I'm kind of surprised that they'd give something out to clients that'd make them vulnerable. Way back when I worked in a library, we used barcode labels on each item for the library management system. We'd have people return things with extra lines coloured in the barcode, who always swore that they didn't do it, and it must have been like that when they borrowed it. It never occurred to them that we knew that was rubbish. The items were scanned on the way out, and back on the way in. If it was tampered with beforehand, they'd have errored when first scanned. We made them stump up the cash for relabeling. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
