RFID Card Access Control

From One RFID Card Reader to a Multi-Site Card Access Control System

Every metal key you hand out is a copy you can never take back. An RFID access control system changes that. Users tap a card or fob at an access control card reader, the door unlocks and every entry is logged. When someone leaves, deactivate their credential in seconds instead of rekeying. King Locksmith And Doors installs door access control systems for offices, warehouses, medical practices and apartment buildings across Maryland, Washington DC and Northern Virginia.

Why Businesses Choose RFID Card Access Control

Keys can't be tracked. Cards can

An RFID card access control system records every entry by credential, door and time. Pull an audit trail after an incident, verify contractor hours or confirm that the back door stayed locked overnight.

No more rekeying

Lost card? Terminated employee? Deactivate the credential from your management software. The lock, the reader and every other cardholder stay exactly as they were.

Schedules that enforce themselves

Unlock the front door for business hours, restrict the server room to IT staff and hold holiday closures automatically. RFID door access control follows the rules you set without a manager standing at the door.

Scales with your building

Start with one RFID card reader at the main entrance and expand to elevators, parking gates, storage rooms and secondary sites on the same platform.

Keypad Access Control: Codes Instead of Cards

Not every door needs a credential. Keypad access control gives you a PIN-based entry point for spaces where issuing cards isn’t practical delivery entrances, cleaning crew access, shared storage or after-hours staff doors.

Modern keypad readers support individual codes per user, time-limited temporary codes and instant code changes. We install standalone keypad locks for single doors and networked keypad access control that reports back to the same software as your card readers.

RFID Keypad Access Control: Card + PIN for Sensitive Areas

For the doors that matter most, combine both technologies. An RFID access control system with keypad requires a card and a PIN, so a stolen credential alone won’t open the door. King Locksmith And Doors installs RFID card readers with keypad from leading manufacturers, configured for the level of security each opening needs:. Whether you call it RFID card and PIN access control, card plus PIN access control or a dual-authentication door, the goal is the same: verified entry at the openings where a single credential isn’t enough.

Card or PIN

either credential opens the door, ideal for lobbies and general staff entrances.

Card + PIN

Two-factor entry for server rooms, pharmacies, cash offices, records rooms and executive suites.

Scheduled modes

card-only during the day, card plus PIN after hours, on the same RFID keypad reader.

What is an RFID access control system?
It’s a door access control system that uses radio-frequency identification cards or fobs instead of keys. A reader at the door recognizes the credential and signals the lock to release, while the controller records the event.
In most cases, yes. RFID card readers with keypad can replace existing card-only readers on the same wiring and controller, adding card + PIN capability to doors that need it.
Access control systems are installed with battery backup, and locking hardware is configured to fail safe or fail secure based on code requirements for each door.

Anywhere from one to hundreds. We size the controller and software to your current needs with room to grow.
