I’ve used both my Mastercard and my Visa card here in the USA, in restaurants and shops in Massachusetts and New Hampshire, and I’ve not once had to sign a credit card slip. Apparently, at least for purchases under $25.00, this is the rule here now. Weird.

Which is not to say that having to sign was ever a great security feature, but you’d think that the direction would be from signature to PIN (the model in Europe), rather than from signature to nothing.
