The blue MB sign identifies Portugal's shared Multibanco network. To a visitor it can look like an ordinary ATM, but Portuguese bank cards unlock a much wider menu of services than cash withdrawal.
The blue square with a long menu
MULTIBANCO
A shared national payment network, not merely the Portuguese translation of ATM.
It started with twelve machines
Multibanco launched in September 1985 with twelve ATMs in Lisbon and Porto. Its shared-bank model helped the network spread nationally and turned one terminal into infrastructure for far more than withdrawals.
Portuguese cards open the full toolbox
A visitor sees a smaller country
An international Visa or Mastercard may work for cash withdrawal while local service payments remain unavailable. That is normal: the machine can only offer operations supported by the network, the card and its issuing bank together.
MB and ATM are different signs
The Portuguese tourism board distinguishes the national network marked MB from an international network marked ATM. Read the branding and every fee screen before continuing rather than assuming all cash machines follow one price model.
The card logo still decides at the shop
A merchant is not required to accept cards and may choose accepted brands and card types. Look for Visa, Mastercard, Multibanco or other acceptance marks at the entrance and till, especially in smaller businesses.
