What are the advantages of a bar code reader?

Answer 1

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.

Answer 2

A magnetic strip reader does exactly what it says: it reads the magnetic strip on the card that the strip is attached to. The most common cards with magnetic strips are of course debit and credit cards, but the usage of magnetic strip readers is much wider. A number of ticket solutions, for instance for parking, coffee machines or toll roads also use magnetic strips.

The information that is read by the reader depends very much on the type of application and is determined by standards for the card/reader combination and needs to be implemented by the issuer of the card.

Answer 3

One of the advantage of the magnetic stripe reader is that it is simple for people to use and does not need any training. The other advantage is that the security can be improved by the use of PIN numbers.
