It also entitles you to a cheque-book. Second, you've got a deposit account, which usually pays about 3. 5% interest, less tax. In that respect, a deposit account's a better investment than a current account. However, though you are entitled to a cheque-book, you can only withdraw up to a certain sum each month.
