It's "not as good as chip+pin" for yet another reason: I've encountered ticket vending machines, at entry points to unstaffed Dutch railway stations, that require chip+pin cards for ticket purchases. Chip+signature cards (like magstripe+signature cards) are out because there's no provision for recording a signature on a 9-key PIN-pad, and there's no human eye to match any signature with that on the reverse of the card; and the vending machines vend no tickets without a card having been (successfully) charged.

When was the last time a cashier actually tried to compare the signatures? I don't think they're required or expected to do so. The signature is just intended to be part of the record, for use in potential fraud investigations. Many places where I make credit card purchases don't even ask for signatures. I don't know if there's any particular rule for who does and doesn't. It doesn't seem to be the type of business: some supermarkets want it, some don't. I guess it's just a matter of whether they've chosen to purchase POS equipment with the electronic signature pads or not. -- Barry Margolin, barmar@alum.mit.edu Arlington, MA *** PLEASE post questions in newsgroups, not directly to me *** |

My US chip card does chip+signature if the terminal supports it, otherwise it does chip+pin. That seems fairly common. See this dandy Google doc that lists all US chip card issuers: https://docs.google.com/spreadsheet/ccc?key=0Ani-u3tGk5hedGRvcE1ELVg5UmlGZk01SHZvTUMxdUE#gid=0 |

Not really. Remember you wrote that a > ... Service Order person told me that "Speed-Dial 30" is now a "grand- > fathered" offering, not available to new subscribers ... Now what easier way is there to remove feature M from your slew of features A through Z than to remove everything, and then restore all features but M? That is, to provision features A through L and features N through Z, as though provisioning a new subscriber? Problem was, they couldn't provision a feature that's no longer available to a new subscriber. No mystery at all, there. But if you're lucky you'll encounter some old-timer who'll have a way to reverse all the damage, by first restoring your service to all it used to be, and then selectively deleting only the feature you no longer want. Here's hoping for the best :-) ! Cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP. |
