no one knows why they just r
sorry 4 the lame answer but i can't find it anywhere
Yes, credit cards often have a magnetic stripe on the back that contains the account information in a machine-readable format. The magnetic stripe is used when the card is swiped at a point-of-sale terminal.
The stripe is effectively a short piece of magnetic recording tape. The swipe reader contains a 3-track head (similar to the stereo 2-track head used in audio cassette tape recorders). When the card is pulled quickly and smoothly past this head the data is read and sent to a microcomputer, which decodes it and sends the account number to the bank so the proper transactions can be made.
The ones in hotels and motels do. They are basically the same magnetic stripe card as a credit or debit card.
Refrigerator doors with magnetic closures. Magnetic resonance imaging (MRI) machines. Magnetic levitation (maglev) trains. Magnetic compass for navigation. Magnetic stripe cards for data storage and identification.
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.
Magnetic stripe readers
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.
Magnetic stripe card was created in 1960.
A magnetic stripe reader is a device that reads the information encoded in the magnetic stripe on the back of cards, such as credit cards, debit cards, and ID cards. It works by passing the card through the reader, which detects the changes in the magnetic field and interprets the data stored on the stripe. Magnetic stripe readers are commonly used in point-of-sale systems, access control systems, and various identification applications. They facilitate secure transactions and streamline access management in numerous industries.
A card reader reads the magnetic stripe on the back of credit cards. This device contains a magnetic head that scans the stripe to retrieve information stored on it, such as the card number and expiration date. This data is then used to process transactions.
A magnetic stripe card contains a magnetic stripe that stores information. Unlike smart cards, magnetic stripe cards are passive devices that contain no circuits. These cards are sometimes called swipe cards: they are read when swiped through a card reader.

ATM cards have a magnetic stripe on the back that contains information such as the card number and expiration date. When the card is swiped at an ATM machine, the magnetic stripe is read by a magnetic card reader, allowing the machine to access the necessary account information to complete the transaction.
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.

Electromagnets are used to encode information onto a credit card's magnetic stripe. Data is written onto the magnetic stripe by changing the magnetization of tiny magnetic particles embedded in the stripe using an electromagnet. This process allows the credit card to store and transfer information when swiped through a card reader.
