The DorTag Plus reader is an RFID proximity reader head (antenna) used with DorTag access control systems such as:

• DorTag VI
• DorTag Plus controllers

 It is not a controller itself—it’s the reading device that detects RFID cards/tags and sends the data to the controller for access decisions.

Core Features

RFID Reading

• Reads 125 kHz proximity tags/cards
• Typical technologies:
  • EM4100 / TK4100

Physical Design

• Compact reader head (antenna type)
• Often:
  • Plastic or stainless steel housing
  • Wall-mounted near entry point

Indicators

• LED (bi-colour) for status
• Buzzer for read confirmation

Technical Specifications (Typical DorTag Reader)

Read range depends on tag type and mounting surface

Functional Role in System

What the reader does:

• Detects RFID card/tag
• Sends unique ID to controller

What it does NOT do:

• Does not store users
• Does not control locks directly

All logic is handled by the controller (e.g., DorTag VI)

System Integration

Typical wiring:

Reader → Controller

• Power (+ / –)
• Data lines (D0 / D1 or similar)
• LED/Buzzer control

Controller → Door system

• Relay output → lock / gate motor

Use Cases

• Entry reader (outside door)
• Exit reader (inside door, optional second reader)
• Gate access control

DorTag systems can support:

• 1 reader (entry only)
• 2 readers (entry + exit)

Important Practical Notes

Compatibility

• Must match:
  • DorTag controller
  • Frequency (125 kHz)

Cable limits

• Max ~15m with shielded cable
• Poor wiring = unreliable reads

Security

• Uses low-frequency RFID
• Easy to deploy, but:
  • Lower security than MIFARE systems
