Question

1.) On which card the data is permanently stored?
a) Smart card
b) Magnetic card
c) MICR
d) OMR ​

Answer 1

Answer:

The data used to produce counterfeit cards is called “track data,” and it's stored on the magnetic stripe on the back of your credit card. ... Most credit card payment systems use Track 2 to process transactions.

Answer 2

Explanation:

Optical Mark Reader(OMR)

Optical mark recognition (also called optical mark reading and OMR) is the process of capturing human-marked data

from document forms such as surveys and tests. They are used to read questionnaires, multiple choice examination

paper in the form of lines or shady areas.

he prime function of the OMR machine is to scan and capture the optical marks on the multiple choice scoring sheets,

and save the data into an output file which you can use to perform further analysis.

Magnetic Ink Character Recognition is a character recognition system that uses special ink and characters. When a

document that contains this ink needs to be read, it passes through a machine, which magnetizes the ink and then

translates the magnetic information into characters. MICR technology is used by banks.

Magnetic Ink Character Recognition is used for the printing of bank checks on blank stock. Unlike toner (ink) used for

general text printing, MICR toner has a high iron oxide content so that it can be read by electronic bank processing

equipment.

A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-

based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called

swipe card or magstripe, is read by swiping past a magnetic reading head.

On magnetic stripe cards, the data is permanently stored on a magnetic stripe. The card often includes name and

signature or any other details for added security

Smart card readers

Smart card readers are used with smart cards which are a type of plastic technology card with a built-in chip used for

electronic processes including personal identification, access control, authentication, and financial transactions. Smart

card readers obtain or “read” this type of data. Smart cards are known as intelligent cards in which data can be stored

and updated on the RAM chip. Hackers can not get details easily from smart cards.

Radio Frequency Identification (RFID)

RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic

or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object,

animal or person.

A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio

transmitter-receivers called interrogators or readers send a signal to the tag and read its response. RFID tags can be

either passive, active or battery-assisted passive.
