Why do you need to sign cheques at an ATM? Are these cheques you are
depositing (how quaint!) or do you need to sign it to get cash? I haven't
physically signed (pen and ink) anything relating to financial transactions
in years, except for the occasional EC- or credit-card payment where they
want a signature rather than a PIN. (Many EC-card payments are via PIN
rather than signature now, and in Scandinavia almost all credit-card payments
are by PIN as well---not just cash withdrawls.)
