Embodiment Construction

[0032] The present invention is described by examples below, and it should be noted that the examples listed should not be construed as limiting the invention.

[0033] As shown in the figure: a digital magnetic head of a magnetic card reader in this embodiment includes a magnetic head and an internal decoding circuit of the magnetic head. An operational amplifier, the operational amplifier is connected to the output interface, and one pin of the output interface is connected to the input terminal of the CPU through a Schmitt trigger; the circuit is powered by a 3.3V voltage regulator. The magnetic head is a three-track magnetic head. The output interface is RS232 interface or USB interface.

[0034] Introduction to the working principle of the circuit: CON7 is the access terminal of the three track coils of the magnetic head. The electromagnetic signal generated when swiping the card is amplified and shaped by U1, and the signal is converted into a series of pulse signals, a...

Abstract

The invention relates to a digital magnetic head of a magnetic card reader and a control method thereof. The digital magnetic head of the magnetic card reader comprises a magnetic head; a signal output end of the magnetic head is connected with a signal shaping circuit which is connected with a CPU; an output end of the CPU is connected with an operational amplifier which is connected with an output interface; one pin of the output interface is connected with an input end of the CPU through a Schmitt trigger; and a 3.3V voltage stabilizer is adopted to supply power to the circuits. The digital magnetic head can be connected with any computer or terminal with an RS-232 serial port or USB interface, is supplied with power by standard DC+5V, can read magnetic stripe cards with between 300 and 4,000 Oe or magnetic stripe information on deposit books, has simple operation, stable and reliable performance and good compatibility, is ideal peripheral equipment of a computer system, and can be widely used in various fields such as finance, post and telecommunications, traffic, customs and the like, particularly for reading credit cards, magnetic cards and deposit books of a bank system.

Description

technical field [0001] The present invention relates to a digital magnetic head of a magnetic card reader and its control method, in particular to a method that can directly read the data of credit cards, magnetic cards and passbooks in the banking system without adding a decoding circuit, and directly transmit them through the RS232 interface or USB interface. Digital heads for computers or terminals and their control methods. Background technique [0002] At present, as we all know, the use of magnetic cards has a long history. Because the magnetic card is low in cost, easy to use, easy to manage, and has certain security features, its development has been supported by many world-renowned companies, especially the government departments of various countries for decades, making the application of magnetic cards very popular. all aspects. [0003] Magnetic card recording principle: [0004] The recording head consists of a ring-shaped iron core with a void inside and a wi...
