They are two different things.

- The credit card is inserted into the chip reader

- If card is valid, transaction approved
- If card is illegimitate or reported stolen, transaction refused
- Customer is prompted to insert PIN
- If the inserted PIN matches the PIN on the card, transaction approved
- If the inserted PIn does not correspond with the PIN on the card, transaction refused

We studied this:
What is multimedia?
The main ways that the computer can feed the user's senses is through the use of:
colour
motion of areas of the screen as appropriate
a range of standard shape tools such as rectangles and circles
sound
motion through the use of motors
Games on computers first started out without any sound at all, and many people thought that the inclusion of sound to a game would not make much difference. In fact it was soon found that adding even simple sounds enhanced the overall experience of the computer user.
The use of multimedia also allows the possibility of user input to make selections and choices. This is called interactive multimedia, because the user interacts with the material in some way.

Examples of multimedia
If you send a CD of digital photos of your party to a friend, and you add some sound clips, you are preparing a multimedia presentation because you are using more than one type of media.
Video is a good example of multimedia in that it uses colour, onscreen motion and sound. However on a computer it can also have the user interact with the material eg:
stop the display
go to various places on the video
answer questions that are posed
select from various options that are presented by the interactive package
an educational type of package can ask for help or extra information
A virtual reality application - eg a cockpit simulator that's used to train pilots on the ground - is an example of multimedia. In a virtual reality simulator the pilot, though not actually in the plane, feels as though he/she is.
A wide range of multimedia programmes are available on other formats, for example, educational training packages to learn a foreign language or a CD ROM/DVD encyclopaedia.

I've got a bit more on that if you need it
