There are reasons to be more comfortable with them using a punch card system: * All their "software" (ha!) is stored in physical form, on a shelf, as a board full of wires--hard to mistakenly delete it or lose the registration key. * Their code has 60 years of testing behind it * Cards provide a physical record while also being machine-readable and, as I pointed out elsewhere, if a card gets mangled, well, you just sit down and type up a new copy * They'll never lose your credit card details to hackers * They're comfortable with the technology and have a very clear process. You'll never call them to hear, "Oh, well, they just updated the system and now I can't find the link to our invoice archives"
