At present, bank cards with magnetic strips are still widely used. For example, when depositors lose or replace bank cards or credit cards, if mandatory degaussing measures are not taken, the user information on the magnetic strips will be completely preserved. This security loophole , Is used by some criminals. By reading the magnetic stripe information, all user information can be collected. And to copy and crack. Use normal depositors to bear unnecessary losses. Therefore, the issue of information security in the banking industry has become a key issue considered by major banks.

In June 2013, under the entrustment of China UnionPay, Hunan Forever Elegance Technology Co.,Ltd process design “640kA/m static magnetic field tester”, the instrument requires a large uniformity area (can cover the entire credit card range ), high magnetic field accuracy (magnetic field accuracy not less than 0.5%), high uniformity (uniform area range not less than 0.3%) requirements.

Hunan Forever Elegance Technology Co.,Ltd With its own years of experience in magnetic circuit design, through 1 month’s design calculation and processing, the products are sent to “Hunan Provincial Institute of Metrology and Inspection” for inspection. The acceptance of all indicators of the static magnetic field was completed at one time. This has given companies a great deal of confidence in the magnetic field calibration. The magnetic field calibration can basically be consistent with the relevant American equipment standards (the 160kA/m standard magnetic field delivered to McGregor in the first half of 2013 is also fully consistent with the company's American equipment).
