low
Low coercivity magnetic stripe cards store data on a magnetic stripe using a magnetically soft material. These cards use lower magnetic energy, typically around 300 Oersted, making them easy to encode and erase. Businesses often use them for hotel keys, time cards, and membership passes. Because of their low coercivity, they are vulnerable to accidental erasure from magnets or electronic devices. Users must avoid strong magnetic fields to prevent data loss. The encoding process requires less power compared to high coercivity cards. Though inexpensive and simple to produce, low coercivity cards are better suited for short-term or low-security applications.
