My first big intro to this, was when we took banking terminals designed in Hawaii, to Las Vegas in the winter. We did not do that well, resetting on E-Field from people walking by at 10-15' distance. Later versions did just fine on the show floor, in ABS plastic cases, and I couldn't even zap them with my "special" shoes on. Meanwhile, across the row, the guy from Diebold, with his stainless steel ATM is out spritzing his carpet with water.. I did kill a competitor's terminal at the same show, just touching the buttons. But I wasn't trying to, I just touched the keypad. Honest. :) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
