Digital RFID Card Door Lock

Digital RFID Card Door Lock is a type of electronic lock that uses Radio Frequency Identification (RFID) technology to allow access without the need for a traditional key. Instead, users gain entry by tapping or waving an RFID card, tag, or even a mobile device near the lock's reader. Here's a quick overview of its components, functionality, advantages, and applications

Key Components

RFID Reader – Scans the RFID card or tag.
Microcontroller/Processor – Verifies the credentials stored on the card.
Electronic Lock Mechanism – Unlocks the door upon successful authentication.
Power Supply – Usually battery-operated; some have backup power or are hardwired.
Management System (optional) – For programming cards and logging access.

How It Works

A user presents an RFID card or tag near the reader.
The reader captures the unique ID stored on the card.
The system verifies the ID against a pre-authorized list.
If it's a match, the door unlocks electronically for a few seconds.

Advantages

Keyless Entry – No need to carry or manage physical keys.
Security – Harder to pick than traditional locks; access can be logged and controlled.
Convenience – Cards can be activated, deactivated, or reassigned easily.
Integration – Can be linked to time-attendance or surveillance systems.
