If the information is not read, the issuer will decline the transaction, regardless of any disposable amount on the connected account, except in the Asia Pacific region, where manual keyed entry is permitted under some circumstances. This is different from most other debit and credit cards, where the information can be entered manually into the terminal (i.e. by typing the 13 to 19 digits and the expiry date on the terminal) and still be approved by the issuer or stand-in processor. In most countries, other than those specified in Mastercard's rules, a PIN rather than a signature is always required to authorise a Maestro transaction, except where no CVM (Cardholder Verification Method)[3] is required.
