Users can simply tap their NFC-enabled cards or smartphones against a reader to gain access. This system is becoming increasingly popular for its convenience and security features.

2. How does traditional key systems work?

Traditional key systems require a physical key to unlock doors. Users must carry the key with them at all times, and if they lose it or someone else gets a copy, security can be compromised. Additionally, locks may need to be changed if a key is lost or stolen, which can be costly and time-consuming.

2. Increased Security: NFC systems typically offer advanced encryption methods that can be more secure than traditional locks.
3. Access Management: It is easy to grant or revoke access from a central system without changing locks.
4. Audit Trails: Many NFC systems provide records of who accessed what and when, enhancing security monitoring.

4. What are the disadvantages of NFC door access control?

1. Dependence on Technology: If the system fails or the reader malfunctions, access can be denied.
2. Initial Setup Cost: The upfront cost of NFC systems can be high compared to simply using traditional keys.
3. Battery Dependency: Some NFC systems might require batteries, which need to be monitored and replaced.

5. What are the advantages of traditional key systems?

1. Simplicity: Traditional keys are easy to understand and require no technical knowledge.
2. Low Initial Cost: The initial investment for a traditional lock system is usually lower than an NFC system.
3. No Power Source Required: Keys do not require batteries or electricity to function.

1. Security Risks: Keys can be lost, stolen, or duplicated, compromising security.
2. Inconvenience: Carrying multiple keys can be cumbersome, and users often face issues with remembering which key goes to which lock.
3. Access Management Issues: Revoking access requires changing locks or re-keying, which can be costly.
