Device for simulating magnetic data transmission by mobile phone

Abstract

The invention discloses a device for simulating magnetic data transmission by a mobile phone. The device comprises the mobile phone, and a transmission module and a drive circuit mounted in the mobile phone. The transmission module comprises a magnetic material and an excitation circuit; the drive circuit is configured for receiving coding signals obtained by processing magnetic data stored in the mobile phone; the drive circuit generates an alternating magnetic field through the transmission module; the generated magnetic field signals are sensed by an external reading magnetic head, thus finishing reading the magnetic data. According to the method, the magnetic data can be transmitted and read securely and reliably only by placing the mobile phone at a position close to the magnetic head; the device has high compatibility with the existing magnetic data reading system; many cards in one machine can be realized; and the device can be applied in multiple aspects such as magnetic data management and storage conveniently.

Description

technical field [0001] The invention relates to magnetic data (or called magnetic strip data) storage and transmission technology, in particular to a device for simulating magnetic data transmission using a mobile phone. Background technique [0002] Magnetic storage technology has been developed for 100 years, and it is widely used in our daily life, such as magnetic stripe cards, magnetic card train tickets, computer hard disks, etc. Magnetic storage is represented by two different magnetization states of magnetic materials coated on the surface of the carrier "0" and "1" of binary information. Coating the magnetic material evenly on the circular aluminum alloy or plastic carrier becomes a disk, coating on a paper card becomes a magnetic ticket, and coating on a plastic becomes a magnetic stripe card. There are quite a lot of magnetic storage products in life, such as magnetic card train tickets or magnetic stripe air tickets in the ticketing system, but one-time use not ...

AI Technical Summary

Problems solved by technology

Magnetic media data is stored with different electromotive forces generated by magnetic polarity. When the magnetized material is affected by external energy, such as heating and impact, the magnetic moment direction of each magnetic domain will become inconsistent, and the magnetism will be weakened. or disappear, resulting in data confusion and loss

[0004] For example, magnetic card train tickets or magnetic stripe air tickets are one-time use, and the security is insufficient, such as false use, degaussing and other problems; magnetic stripe cards are used in daily life as identification, financial management and other functions, but with the As time goes by, as the number of magnetic stripe cards increases, management and carrying become a hassle

And the problems of degaussing, leakage, transmission and density encountered in existing magnetic media storage (meaning magnetic stripe cards, magnetic tapes, magnetic disks)

Magnetic media storage technology has been used for many years. With the evolution of technology, some problems in use have not been solved
