RFID More Hackable Than Retailers Think?

Iphtashu Fitz writes "Lukas Grunwald, a senior consultant with DN-Systems Enterprise Solutions GmbH, is warning retailers that the RFID technology that they are quickly adopting can easily be hacked with the appropriate tools. Grunwald has written a program called RFDump which lets you read and display all metadata within an RFID tag and also modify the user data using a text or hex editor. He wrote this program to demonstrate how consumers can protect themselves by wiping out RFID data after purchasing a product but he acknowledges that it would be trivial to abuse this behavior. What, you might ask, can you do if you hack an RFID tag? Well as the technology is adopted more widely a thief could conceivably mark down the price of an expensive piece of jewelry before paying for it at an automated checkout counter, underage hackers could purchase alcohol or adult movies, and pranksters could simply reprogram the inventory of an entire store by just walking up and down the isles. 'The people who will be using this (shopkeepers) don't know much about technology,' Grunwald warned."

A Plan for the Improvement of English Spelling
by Mark Twain

For example, in Year 1 that useless letter "c" would be dropped to be replased either by "k" or "s", and likewise "x" would no longer be part of the alphabet. The only kase in which "c" would be retained would be the "ch" formation, which will be dealt with later. Year 2 might reform "w" spelling, so that "which" and "one" would take the same konsonant, wile Year 3 might well abolish "y" replasing it with "i" and Iear 4 might fiks the "g/j" anomali wonse and for all.

Jenerally, then, the improvement would kontinue iear bai iear with Iear 5 doing awai with useless double konsonants, and Iears 6-12 or so modifaiing vowlz and the rimeining voist and unvoist konsonants. Bai Iear 15 or sou, it wud fainali bi posibl tu meik ius ov thi ridandant letez "c", "y" and "x" -- bai now jast a memori in the maindz ov ould doderez -- tu riplais "ch", "sh", and "th" rispektivli.

Fainali, xen, aafte sam 20 iers ov orxogrefkl riform, wi wud hev a lojikl, kohirnt speling in ius xrewawt xe Ingliy-spiking werld.
