Chip and Pin Woes

(updated )

I have the pleasure of having a UK money in a bank account and credit card. This is great, because UK cards are the only ones that don't charge exorbitant currency-conversion charges when you use them overseas. I live in Cape Town, so I'm almost always using it overseas.

Chip and Pin, never used to be supported on South African credit card equipment, but these days, it's mandatory in UK, and supported on almost all credit card machines. Back when it wasn't supported people just used to swipe the card. Now, they actually try and read the chip. The procedure is something like this:

  • "Ready"
  • "Insert card"
  • "Swipe card"
  • "Insert card"
  • etc.

At some point, they give up, and ask for another card. The good ones can go between swiping and poking in a fraction of a second, in the belief that the faster they do it, the more likely it is to work. The only real solution seems to be to get the supervisor card out, and override Chip mode....

I thought that was all, until yesterday, when I got an even more interesting error message: "The PAN length does not comply with the min/max length in the BIN file". Does anyone know WTF that means??? :-)
