The credit card magnetic strip is made up of tiny magnetic particles that are arranged in a specific pattern. When the strip is swiped through a card reader, the magnetic particles are read by the reader and converted into binary code, which is then processed by the system to authorize the transaction.
The magnetic strip typically contains the cardholder's name, account number, expiration date, and a security code. This information is encrypted and can only be read by authorized card readers.
The plastic bag trick involves placing a plastic bag over the magnetic strip of your credit card to prevent it from being demagnetized. This is because the plastic bag creates a barrier between the strip and any external magnetic fields that could potentially damage the strip.
No, the plastic bag trick is a safe and effective way to protect your credit card's magnetic strip. However, it is important to note that the plastic bag should not be placed over the chip on your credit card, as it can interfere with the chip's functionality.
It is recommended to use the plastic bag trick on your credit card whenever you are in a situation where there may be strong magnetic fields, such as near electronic devices or in certain types of wallets. It is also a good idea to replace the plastic bag every few months to ensure maximum protection.
