The magnetic strip holds the information of your card.
The data stored on a credit or debit card is stored not only in the metallic chip - but also on a magnetic strip on the rear of the card. Magnetic card readers read the data from the strip on the card, instead of the embedded chip.
Take a magnet, swipe it on the magnetic strip on the card.
If it is a standard ATM card and not a debit card, there is no relationship between the card number and your bank account. All that information is stored on the magnetic strip on the back of the card.

No, photocopying a credit card does not destroy the magnetic strip, but unless you absolutely need a copy of your credit card, I would not suggest making copies of it. If you have a copy of the card (especially if you put front/back on the same page or stored together), it would make it very easy for someone to steal that information and use your card for online purchases.
The word EFTPOS is an acronym stands for 'Electronic Funds Transfer Point Of Sale'. An EFTPOS Machine allows a seller to directly debit a customer's bank account by using a debit card or credit card. A debit or credit card is the same as an ATM card. The card is swiped through a magnetic strip reading device on the EFTPOS Machine, and after a customer enters his or her PIN number the transaction is authorised and funds transfer from the customer's account to the seller's account with 24 to 48 hours or 2 business days. EFTPOS Machines can be integrated with other Point of Sales hardware to save users having to enter in the transaction amounts, which could result in user error, allowing for a more automated process. It should be noted that EFTPOS is generally an Australian term and is not widely used in the rest of the world.
Why do credit cards have a magnetic stripe on the back
A credit card is a piece of plastic with a strip of magnetic information on it. When this strip is exposed to a strong magnetic field, like in an MRI, PET scan, or CAT scan it can get erased because the magnetic field removes the magnetic information.
