Rfid Aluminum Foil Blocks Credit Card Bank Id Card Holder Cases

Is the anti-degaussing card holder useful?
When placing the bank card, put the side with the magnetic strip into the pocket where the card is placed in the wallet to avoid scratching the magnetic track. When taking it out for use, avoid the direct contact between the magnetic strip and the magnet. Under normal circumstances, the damage of the magnet of the wallet to the magnetic track of the bank card cannot be avoided, but it has little effect. The magnetic stripes of bank cards have a great influence on the magnetic stripe: self-service bank access control systems, POS consumer card swiping, ATM withdrawals, counter keyboard card swiping transactions, etc., and each device has different magnetic recognition rates, it is possible that ATM withdrawals are successful, and POS swiping cards If unsuccessful, the use of self-service equipment is successful, and the use of over-the-counter transactions is unsuccessful. The magnetic field generated by the electrical appliances in use also has a strong influence on the magnetic track of the bank card within a short distance. General error report: The prompts such as the inability to recognize the expensive card and the invalid card indicate that there is a problem with the magnetic track of the bank card and cannot be recognized, and the card needs to be replaced or magnetized at the issuing bank. The plastic card sleeve cannot block the influence of the magnetic field on the bank card, but it can prevent the magnetic track from being physically damaged, such as sassafras injury and hanging injury. Do not put bare cards together with sharp and hard objects such as keys and knives, also to avoid scratching the magnetic stripe.
