I Install, and repair ATMs for a living for NCR. I know a thing or 2 about them, their software, PCI compliance, 3DES, (known as Triple DES), communications between the ATMs, and the Financial Networks. My question to Jaccob is still relevant. Why is it shame on Toms for including both those items in an article? Most of the people on these forums automatically blame Target for storing the information, which as already pointed out is against PCI regulations, and the regular PCI audits (If you think Revenu Canada, or the IRS Audits are bad, try a PCI compliance audit) that organizations go through would pick that up. No company worth a grain of salt would do that. Especially as large as Target. Also, any stored transactions (usually stored for atleast 6 months, don't include the PIN, and are used for evidence against chargebacks), are stored in highly secure databases using Random SALT.
PIN (Personal Identification Number) ohhh thank you so much for clearing that up for me, is the same for your bank card (Debit Card as we call it up here) when using it at the ATM (also thanks for pointing out Automated Teller Machine), or a POS (Point of Sale). Same PIN both places.
If you don't know the industry, or how it works, simply STFU.
