[CQ-Contest] Dayton Crown Plaza Credit Card flaw

My understanding is that IHG caused their own problem because they used
old-fashioned "swipe" terminals instead of modern chip terminals.  (Chip
information is encrypted.)

But don't feel overly safe.  Even credit card chip technology in the U.S.
is less secure than elsewhere.  A lost U.S. credit card with chip can be
used anywhere by anyone until canceled.  A European credit card, however,
cannot be used without the owner's 4-digit PIN in addition to the chip
(same as debit cards, but not credit cards, in the U.S.).
