What is a card holder? Used to avoid degaussing

This problem is really annoying, I have encountered the problem of continuous degaussing several times, I will talk about my method now, I hope it can help you.

1. When you buy a wallet, there are generally a few small hard cards introduced by the brand, don't throw them away! When putting the card, in addition to the card can not be in the same mezzanine, put a card of this kind on the side with a magnetic stripe to play a spacing role.

2. ICBC has a special bank card sleeve, which has a good effect and can be used for several purposes.

3. It's not bad to use your ID card as a spacing.

I now use all three methods, a money package 4 bank cards, a few months is no problem, you must know that I used to degauss three cards a week, it doesn't matter if you spend a little money to replace the card, you can't afford that time! It also depends on the faces of the bank staff!

If that friend has a better way, post it and let's talk about it.

Finally, it should be noted that the bank card should never be placed directly in the same pocket as the mobile phone, which is very likely to demagnetize quickly!!

Card sleeves are something you can make and buy by yourself, there are cloth, there are paper, there are plastic! It depends on personal hobbies!

The card sleeve has leather and cloth. The size is the same as the card.

It is sold in many gift shops.

It is safe to put it in the wallet or not to put it in the card holder.

Because there's a good chance that there will still be friction.

If the magnetic card is demagnetized, it will be more troublesome to do business. Let's talk about how to avoid the degaussing of the base noise magnetic card.

01 The most taboo thing about magnetic cards is to put them together with mobile phones and other electronic products, which is particularly easy to demagnetize, so the magnetic card Hufeng should not stay away from the mobile phone and put it separately.

02 Do not store many magnetic cards stacked together, so that the magnetic stripe on the back of it will often rub, and it is easy to wear out the magnetic stripe and cannot be used normally, so it is best to store each magnetic card separately.

03 Do not put the magnetic card together with metal things, such as key chains, mobile phone chains, etc., metal things are easy to be magnetized, and metal things are relatively sharp, which can easily lead to demagnetization or scratches of the magnetic card.

04 Magnetic cards should not be put together with magnetic things, such as the hook and loop of the magnetic pencil case, the hook and loop of the wallet, the magnetic buckle of the mobile phone case, etc., and these things are put together, which is easy to demagnetize, so it should be placed separately in a special card sleeve to be safer.

1. The locks of some backpacks and wallets are "hidden buckles" made of magnets, which should keep the card away from this magnet.

2. Do not keep the card close to a high temperature environment or a humid environment. Generally, the material of the magnetic stripe card is PVC material, and the high temperature will deform and even burn the PVC, which will directly cause the magnetic stripe to be damaged. If the magnetic stripe card is left in a humid environment or soaked in water for a long time, it will also cause the card to open the glue, be damaged, and eventually become unusable.

3. Do not bend the card, and prevent sharp objects from wearing, scratching or twisting the magnetic stripe. Several cards rubbed against each other when placed together, and while they could not demagnetize the cards, they would cause damage to the magnetic stripe area. Therefore, it is best to keep the card in a special card case, or in a protective case.

4. The bank card should be placed in a hard leather folder, and the position should not be too close to the magnetic buckle; Keep the bank card away from high-magnetic places around induction cookers, microwave ovens, TVs, refrigerators and other electrical appliances as far as possible, and try not to put them together with magnetic items such as mobile phones, computers, handheld computers, magnets, Wenquxing, and business passes;

5. The recorded information of bank cards and passbooks is stored on the magnetic stripe on the back, and the strong magnetic field generated by the high-frequency electromagnetic waves generated when the mobile phone is working will magnetize the credit card, making the recorded information disordered, thus causing the bank card to become invalid. At the same time, some residents stuff mobile phones, bank cards and other items in their bags together, which can easily cause bank cards to be "demagnetized".

Hello, it has an anti-demagnetization effect.

The card presented by the bank is made of electromagnetic shielding material. It can effectively avoid the disappearance or information leakage of bank cards, second-generation resident ID cards, information cards, social security cards, etc., and can effectively prevent the damage and fall off of the magnetic layer of bank cards.

Product specifications:,Product built-in:,Suitable for all kinds of bank cards, bank passbooks, social security cards, medical insurance cards, shopping cards, IC cards, bus cards, second-generation ID cards and other magnetic cards.
