How do hotel room keys get demagnetized?

Cards with scratches, exposure to debris, and other types of physical damage can be rendered unusable. Key cards may become inoperable when the magnetic stripe is demagnetized through exposure to magnets. Name tags, signs, and purse and wallet closures, and mobile phones are all potential sources of magnet exposure.

Many people believe that storing hotel room keys near electronics, such as cell phones, can demagnetize them. However, this is also a myth. Hotel room keys are typically made of materials that are not easily affected by the electromagnetic fields generated by electronic devices.

Hotel key cards work by using various technologies such as RFID and magnetic stripe. The information encodes inside the key card can only be read by RFID readers or magnetic readers.

Magnetic stripe technology is the most common method used in hotel key cards. Similar to credit cards, these cards have a magnetic stripe that is encoded with data. When the card is swiped through a card reader, the information is read and then compared to the data stored in the hotel's system.

They may deactivate the key card and issue a new one for the next guest. Charge a fee: Some hotels might charge a fee to the guest's credit card on file for the unreturned key. This fee can vary depending on the hotel and the type of key.

However, this is generally a misconception, as the magnetic fields produced by modern mobile phones are too weak to cause demagnetization of hotel key cards. They deactivate the magnetic strip key cards yes but not the new RFID key cards. The RFID are the ones you just hold up to the lock instead of swiping.
