Magnetic card reader
Magnetic card is the use of magnetic carriers recorded some information that identifies the identity card or other purposes. Depending on the use of different substrates, can be divided into PET magnetic card, PVC card and paper card, three; different structure depending on the magnetosphere can be divided into full-coated magnetic stripe cards and card .
Magnetic easy to use, low cost, extremely versatile and can be used to produce credit cards, bank cards, passbooks, subway cards, bus cards, ticket cards, telephone cards; electronic game cards, tickets, traffic tickets and a variety of charge cards and so on.
With the application of magnetic devices, called magnetic card reader device. Trade names include: magnetic stripe reader, magnetic card reader, card reader and so on.
Second, the principle
The composition of magnetic card reader is a physical shell, which fixed a head, some of the installation of a magnetic body (called degaussing), and encoding and decoding circuits, lights and other components.
Reader Process: Program issued a reader signal, power head, signal amplification, the signal magnetic brush obsolete record, store, and then re-engineering, and then sent to the computer to confirm if it is adopted and found to comply with the output, otherwise an error re-brush .
Write card process: The program issued a written card signal, then amplified degaussing power, power heads, out of date when the magnetic brush after the first delete all contents of the degausser, then through the head to write the content.
Third, the classification
Depending on the magnetic stripe read and write functions can be divided into magnetic stripe card readers and magnetic card reader.
1, Magnetic card reader
Magnetic card reader for reading magnetic information devices. A magnetic card reader / device, magnetic card readers / devices, magnetic card swipe machine / device, magnetic card swipe slot, magnetic card reading machines / devices, magnetic card inquiry machine / device such as trade names.
Different types:
(1) From the body of function points:
a. Ordinary magnetic card reader: the body is not with a keyboard, a single magnetic stripe reading device.
b. Keypad reader: magnetic strip reading device body with a small keyboard to enter passwords.
c. Keyboard reader: on the computer keyboard with integrated card reader, and more for banks.
(2) From the sub-track magnetic card read: single-track magnetic card reader 1, a single 2 track magnetic card reader, single-track magnetic card reader 3; 1 & 2-track magnetic card reader, 2 & 3-track magnetic card reader; full three-track magnetic card reader.
(3) From the computer or terminal port points: keyboard port, serial port, USB (keyboard with imitation imitation of the serial port with the points) and so on.
2, Magnetic card reader
Magnetic card reader for reading, writing credit card, magnetic stripe card or passbook information on this card reader device. A magnetic card reader machine / device, magnetic card reader card machine / device, magnetic card slot to write, write magnetic card machine / device, magnetic write magnetic machine / device, etc. is called.
Different types:
(1) According to the cards were divided into high environmental resistance to anti-magnetic card reader (2750oe or 4000oe) and low resistance to magnetic card reader (300oe). Description: High level of anti-density magnetic card reader on the card can read and write, and low resistance to magnetic card reader can read high and low density of magnetic cards, but only write the magnetic low-density, high-density magnetic card and can not write.
(2) According to the track can be divided into single one magnetic (track) channel magnetic card reader, a single 2 magnetic (track) channel magnetic card reader, magnetic single 3 (track) channel magnetic card reader; 1 & 2 pairs of magnetic ( track) channel magnetic card reader, 2 & 3 card reader; all three magnetic (track) channel magnetic card reader.
(3) From the computer or terminal port points: keyboard port, serial port, USB, etc..
