The reason why the mobile phone chip is demagnetized, there are two main reasons, either it is folded and damaged, or it is often touched by some items that are easy to produce strong electromagnetic fields.
The strong magnetic field generated by the high-frequency electromagnetic waves emitted by the mobile phone magnetizes the magnetic chips in credit cards, ic cards and the second generation, causing the recorded information to be confused, resulting in failure. Together with the card, it is easy to form a second-generation card \"degaussing\
Prevent the mobile phone from degaussing the mobile phone chip:
1. Replace the magnetic stripe card with a chip card. At present, the domestic bank cards are basically chip cards, chip cards will not be degaussed, will only be damaged.
2, pay attention to the magnetic card do not stick to the middle of the iPhone12 back shell, pay attention to yourself, the problem is not big.
,
Chip cards are not demagnetized. Degaussing means that when the magnetized material is affected by external energy, the direction of the magnetic distance of the magnetic domains will become inconsistent, and the magnetism will weaken or disappear, this process is called degaussing.
The remaining magnetic material is placed in the AC magnetic field, and the AC magnetic field strength is gradually weakened until it disappears, and the material is degaussed.
2 Surface scratches, surface wear, use knives and other sharp objects to mark the chip.
3 Cut, the most direct, but also the most laborious, is to cut the chip with scissors
When the chip needs to be broken and degaussed, the chip that needs to be broken and degaussed is first poured into the box through the hopper, and then the crushing mechanism is started to operate to break the chip
Therefore, it is urgent to develop a chip breaking and degaussing device that can make the data in the chip not exist to be recovered, facilitate the collection of the chip that has been broken and degaussed, and prevent the debris from sputtering during the crushing process. In order to overcome the shortcomings of the existing technology, the data in the chip is recovered, it is difficult to collect the chip after crushing and degaussing, and it can not prevent the debris from sputtering during the crushing process.
