## Answer.
### 1. What is Qr Code Door Access?
Qr Code Door Access is a system that allows individuals to gain entry to a building or a specific area by scanning a unique QR code. This QR code is usually generated through a mobile app or a physical card that contains the code. Once scanned, the QR code communicates with the access control system to grant or deny access based on the permissions associated with that particular code.
### 2. How does Key Fob Entry work?
Key Fob Entry, on the other hand, utilizes a small electronic device - the key fob - to grant access to a secured area. The key fob is programmed with a unique identifier that is recognized by the access control system. When the key fob is brought close to a reader, it sends a signal to the system to allow or deny entry based on the access permissions associated with that particular key fob.
In summary, Qr Code Door Access relies on scanning a QR code to gain entry, while Key Fob Entry uses a small electronic device to communicate with the access control system for entry authorization. Both methods offer secure and convenient ways to control access to certain areas within a building.
