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.
Magnetic stripe readers
A magnetic stripe reader is used to read the information stored on the magnetic stripe on the back of cards like credit cards, entertainment cards, bank cards, and other similar cards. The magnetic stripe contains data such as account number and expiration date, which is swiped through the reader to facilitate transactions.

Advantages:- Putting magnetic stripes on the cards are not expensive,so the cards are cheap.Disadvantages:- Magnetic stripes may get damaged or the stripe reader could break down.Sorry, I couln't think of lots but I got one: It contains up to only a certain amount of letters and words :)magnetic card readers operate on magnetic strips, which are inherently susceptable to erasure, it doesn't happen often but it does happen, there are more advantages than disadvantages. another disadvantage is that mag card readers take a lot of wear and tear, the read heads must meet the card with direct tension and precision. the read heads are usually impregnated with diamond dust to prevent wear on the heads so they may read millions of swipes without significant wear that would widen the swipe gap, this diamond dust tends to wear the mag stripe out on the card quicker than the head wears away. mag cards have three areas for data to be stored and these areas vary in bits per inch that may be written to the the areas. more precision is required for higher rates of data bpi. rfid is fast replacing magstripe, it has a more robust security protocol, isn't affected by enviroment and is as compact as the magstripe.
