As of January, 2002, the Euro replaced the drachma as the legal unit of currency in Greece and, at some stage; you’ll need to exchange your national currency, e.g. pounds sterling or dollars, etc, for euros as personal cheques drawn on foreign bank accounts can’t be cashed in Greece.

Travellers Cheques remain one of the safest ways to travel with money. In
the UK you can buy these either in sterling or in euros. If you buy
euro Travellers Cheques then you buy them at whatever the exchange rate
is at that exchange office on that day, i.e. the actual exchange
between pounds and euros occurs when you buy them in the UK. If you buy
sterling Travellers Cheques then the exchange between pounds and euros

Generally, the exchange rate in Greece is slightly better than in the UK overall. Travellers Cheques and bank notes can be exchanged at banks in Greece, also at the main post office in Argostoli and at various exchange offices in resort (usually tour / car hire offices). If you’re staying in a hotel you may be able to change money at reception, albeit at a higher charge. Note: there are no exchange facilities at Kefalonia airport.
Wherever you change your money in Greece it is the norm for the daily bank exchange rate to apply and the standard bank charge of 2% commission (we all have to earn a living). The actual bank exchange rate is liable to vary from day to day and may vary very slightly from bank to bank.
Visa and MasterCard cards are widely, but not universally, accepted in Greece (American Express less so). You should be able to use them to pay for car hire and tours; some tavernas will also accept payment via credit or debit card, as will some garages and some shops. Not all peripteros (cigarette kiosks) will accept them for cigarettes but the Duty Paid shop at the airport will. You can also use most credit and debit cards to withdraw cash from your bank account via ATMs, located as follows: Airport, Argostoli, Fiskardo, Lassi, Lixouri, Poros, Sami, Skala.
