Using an ATM: ATM • Insert a debit or credit card into the magnetic stripe reader. • It will read an account number from the stripe on the back. • ATM will then ask customer to use their PIN (Personal Identification Number) for security. • Customer asked to select an option from a menu on the screen. • To withdraw cash, the customer selects the relevant options and the request is sent to the bank’s mainframe where it is approved and updated. ATM Advantages of using an ATM: • Banks can keep their operating costs down as fewer employees are needed to work at the branches. • Customers have 24 hour access to their accounts seven days a week. • There’s no need to carry large amounts of cash around as the large number of ATMs means that it is readily available.

Types of Cards There are 2 types of card you will need to be familiar with: • A Debit Card; • A Credit Card; Types of Cards A Debit Card: • This card allows the user to transfer money from their bank account to the vendor’s bank account. • The money for the purchase of the item is taken from the customer’s bank account after 1 or 2 days. • The customer MUST have money in the account to cover the cost of the item. Types of Cards A Credit Card: • This card allows the customer to purchase an item even if they do not have enough funds in their account. • The customer is then sent a bill each month totalling the cost of the items bought in that period. • The bill will contain an amount added for ‘interest.’ • The ‘interest rate’ will be determined by the Credit Card provider. Chip and PIN What is Chip and PIN? • Found on debit and credit cards. • Customer places chip into a card reader and is asked to input their PIN (Personal Identity Number). • The PIN is the same one that is used in the ATM. • It is a security measure to stop people forging signatures and using a card fraudulently.
