Spending and borrowing
Good stuff and bad stuff!
Debit Cards 
Debit cards are linked directly to your bank account - when you use them the amount of your purchase is deducted from your account straight away. You can use these cards to buy goods or withdraw cash (and they can be used in hole in the wall machines).
You can also use debit cards to get 'cashback' from shops when you buy goods, the amount of cash you receive is added to the cost of your purchase and the total amount is deducted from your account right away.
When using a cash machine or paying for goods with a debit card you'll need to enter your PIN (personal identification number). When buying goods you usually enter it into an electronic hand held device, but in some cases you may have to sign.
Credit cards
When you use a credit card, you are borrowing money. Credit cards allow you to buy things now and pay later. The credit card companies charge you for this if you do not pay them back within one month of the purchase. This charge is known as the interest rate.
The rates of interest, known as the APR (annual % rate), can be very high.
If you take cash out with a credit card you're charged daily interest from the moment you take out the cash until the credit card bill is paid. This is a very expensive way of borrowing money. You should think about the added cost of borrowing money before you buy any item this way.
