It sounds like you might be referring to a device called a magnetic card reader, which reads information stored on magnetic stripes found on credit cards, IDs, and other types of cards. These readers use magnetic fields to interpret the data encoded on the magnetic stripe and typically interface with a computer or other device to process the information.

What is a magnetic stripe used for?
A magnetic stripe is used to store information on cards such as credit cards, debit cards, and identity cards. The stripe contains important data encoded magnetically that can be read by card readers when swiped.
Where is the magnet inside a VCR?
In a VCR, the magnet is typically located within the video head assembly. This assembly uses magnetic fields to read and write video signals on the magnetic tape. The magnet helps control the tape's movement and alignment as it passes over the read/write heads, ensuring accurate playback and recording.
Why hard disk is magnetized by iron oxide?
Hard disk drives use a magnetic coating of iron oxide to store data because it can be easily magnetized to represent binary data (0s and 1s). The magnetic polarity of the iron oxide particles can be changed by a magnetic head, allowing data to be written and read from the disk.
What does magnetic tape do?
Magnetic tape is a data storage medium that stores data magnetically on a thin plastic strip coated with a magnetizable material. It is commonly used for backup and archiving purposes due to its high capacity and relatively low cost. Data is written to and read from the tape using a magnetic recording head.
Is sulfur magnetic or non magnetic?
Sulfur is non-magnetic. It does not have magnetic properties like iron or nickel, which are considered magnetic materials.

Data is written to and read from a floppy disk via a magnetic?
Yes, data is written to and read from a floppy disk using a magnetic read/write head that interacts with the magnetic coating on the disk. When writing data, the magnetic head aligns the magnetic particles on the disk surface to represent the information. When reading data, the head detects the magnetic orientation of the particles to retrieve the stored information.
What is used to read the information from the magnetic stripe?
Magnetic stripe readers
What is Justin Bieber charcter in the TV show Maggie and the beauty?

What is the purpose of using magnetic ink?
Unlike normal ink magnetic ink can be read by humans and specialized equipment. Magnetic ink is often used to print characters, for example routing numbers, on documents which are read by machines.
Are CD's and DVD's magnetic?
CD's and DVD's are not magnetic. They are optical storage devices that are read with LASER beams.
What is used to read the information from the magnetic stripes on the back of a credit card?
A magnetic stripe reader is used to read the information on the magnetic stripe of a credit card. This device scans the data encoded on the stripe and then transmits it to a computer for processing.
Khushwant singh charcter sketch of the grand mother?

What is used to read the information from the magnetic strip in a credit card?
A card reader, also known as a magnetic stripe reader, is used to read the information stored on the magnetic strip of a credit card. The reader uses a magnetic head to detect and decode the data on the strip, such as the card number and expiration date.
