How To Prevent Your Credit Card From Being Demagnetized
There is nothing more frustrating than continuously swiping a credit card into a reader without result. When the credit card machines cannot read a card, it is usually because the credit card has been badly scratched or demagnetized.
Unlike those old days when credit cards still used a roller, today’s credit cards use a magnetic strip on the back. It contains small pieces of iron that are arranged in binary form that stores important user information. When a magnet is placed too close to the card, iron particles are demagnetized and will make your card unreadable. When this occurs, the card must be replaced immediately.
Since then, some banks charge a fee for replacement card, the best strategy is to prevent your card from being demagnetized. When magnetic credit cards are introduced 20 years ago, wallets made from eel skins are suspected as the cause of faulty credit card or ATM card. In theory, certain species of eel can create strong electrical current and the skin may still have a residual charge to demagnetize the card. The problem with this hypothesis is that wallets made from eel skin cannot be made of electric eels.
Those who have worked in grocery stores were surprised to see why cards stored in eel skin wallets seem to be more easily demagnetized compared to those made from cowhide. It turns out that the culprit was not the skin, but the little magnets on the clasps. Because eel skin is quite thin, the magnet is not powerful enough to encrypt the data completely.
Magnets erase data inside the card through particles realignment and make them completely unreadable. One way to prevent your card from being demagnetized is to avoid magnetic field. Common appliances such as include television set or speaker have strong magnets.
MRI is one thing that you should consider when visiting a hospital. The MRI scans your body using a strong magnetic field, and obviously it will also go through, protective card holders and wallet. Of course, you wouldn’t bring your wallet during a MRI scan, but you might enter the room or put your wallet near the machine, (for example, when you’re accompanying someone or you work there).
Although magnets are typical means of destroying data, neglect can also ruin the magnetic stripe. Men seem to face more problems with faulty cards than women, the difference are maybe on their habit. Most women use dividers to separate their cards, while men tend to stack them together. Storing your cards back to back may damage or erase the stripes, making them unreadable.
Some people resort to purchasing ppi to help them avoid losses in case their credit cards become demagnetized and a replacement is necessary. Though this may sound helpful, it is important that the cardholder be familiar with the terms of coverage. If ppi does not cover instances of losses arising from demagnetization, then ppi claims may be necessary to assist the recovery of premiums paid.
