Compatibility
Check whether the reader supports:
- 125 kHz proximity cards (EM cards)
- 13.56 MHz smart cards
- NFC/Bluetooth mobile credentials
- Keypad backup access
Many modern operators prefer RFID proximity systems because they’re reliable and require no card contact.

- Anti-tamper alarm
- Multi-factor capability (card + PIN)
Higher security areas benefit from smart card and multi-factor models.
Installation Method
Card readers come in:
- Wired (most secure)
- Wireless
- POE-based models
Choose based on your door layout and wiring availability.
Scalability
If you have multiple doors or plan to expand, ensure the system:
- Connects to software or a controller
- Supports adding additional readers
- Allows centralized management
Durability
Outdoor models require:
- IP65 weatherproofing or higher
- Vandal-resistant housing
- Temperature tolerance
Cost
Cost includes the device, cards/fobs, cabling, and sometimes software. For small businesses, standalone devices can be more affordable.

Door Card Reader Types Explained
RFID Card Readers
Most common and ideal for general use. Cards only need to be waved near the reader.
Proximity Readers
A type of RFID reader that works within short-range distances (typically 2-5 cm).
Smart Card Readers
Use 13.56 MHz encrypted cards with advanced security features.
Magnetic Stripe Readers
Older technology requiring swipe motion—still seen in legacy hotel systems but fading out.
Multi-Technology Readers

How Door Card Readers Work
When a card is tapped, the reader:
- Detects the card and extracts its ID number.
- Sends the ID to a controller or internal system.
- Matches permissions with the database.
- Unlocks if authorized.
- Logs the event (time, user, door).
Some readers store permissions internally, while others rely on cloud controllers.
