NFC Chip Memory Locking is a vital security feature in Near Field Communication (NFC) technology, ensuring the safety and integrity of data on NFC chips. This process involves setting the chip’s memory to a read-only state or applying irreversible locking, thereby safeguarding the data against unauthorized alterations. Read-Only NFC Memory allows data to be read but not changed or erased, essential in applications like contactless payment cards. Irreversible NFC Locking permanently disables any further changes to the chip’s memory, crucial in anti-counterfeiting measures.
This locking mechanism is distinct from password protection. While password protection restricts access to the chip’s data, memory locking limits the ability to modify data, regardless of access. It includes static locking, which targets predefined memory areas, and dynamic locking, offering flexibility in choosing memory parts to secure. These features play a critical role in maintaining data integrity in various NFC
