Belgium Guide
Money
The currency in Belgium is the euro (€). Each euro is made up of 100 cents. Euro notes and coins feature a common EU design on one face, but different country-specific designs on the other. There are seven euro notes – in denominations of €500, €200, €100, €50, €20, €10 and €5, each a different colour and size – and eight different coins, including €2 and €1, then 50, 20, 10, 5, 2 and 1 cents. All Euro notes and coins can be used in any of the twelve euro-zone – sometimes "euroland" – states. For the most up-to-date rates, check the currency converter website

ATMs are liberally dotted around every major city and town – and they accept a host of debit cards without charging a transaction fee. Credit cards can be used in ATMs too, but in this case transactions are treated as loans, with interest accruing daily from the date of withdrawal. All major credit cards, including American Express, Visa and MasterCard, are widely accepted in both countries. Typically, ATMs give instructions in a variety of languages.
All well-known brands of traveller's cheques in all major currencies are widely accepted, and you can change them as well as foreign currency into euros at most banks and savings banks, which are ubiquitous; banking hours are usually Monday to Friday from 9am to 4pm, with a few banks also open on Saturday mornings. Outside regular banking hours, most major hotels, many travel agents and some hostels will change money at less generous rates and with variable commissions, as will the foreign exchange kiosks (bureaux de change/wisselkantoren) to be found in key locations in the big cities.
