The 'eat' function is controlled by the card itself. The info about the number of times the code was entered wrong is written on the magnetic strip, and so it doesn't matter when and where is the last time you used the card, it's on there. The transactions done by ATM sometimes (not always) are kept by the machine until remove by human hands and fed to the bank's computer at its headquarters. Hence not much communication between ATM and the outside world. -- "I tawt I taw a tootty tat" Hao-Nhien Q. Vu (pur-ee!l.cc.purdue.edu!vu) (vu@l.cc.purdue.edu) [That's "ell", not "one"]
