What are the methods for demagnetizing anti-theft soft labels?

There are several main methods for demagnetizing anti-theft soft labels:

Electromagnetic demagnetizer: This is the most commonly used method, which uses a strong magnetic field emitted by an electromagnetic demagnetizer to demagnetize the tag. Merchants use demagnetizers to demagnetize the tag when paying to ensure that the tag is no longer detected.

High-frequency electromagnetic waves: Some devices use high-frequency electromagnetic waves to demagnetize the tag. This method can quickly destroy the magnetic material structure inside the tag and make it lose its magnetism.

Physical destruction: In some cases, the tag can also be demagnetized by physical means, such as tearing or cutting the tag, which can directly destroy its internal structure and achieve the purpose of demagnetization.

Heat treatment: High temperature environment can also cause the magnetic material of the tag to fail, but this method is not commonly used because it may damage the product itself.

Usually, merchants use electromagnetic demagnetizers as the standard demagnetization method to ensure efficiency and safety.
