Novus Automation manufactures QR code and barcode readers engineered for access control, visitor management, parking ticketing, and attendance systems. Built in India. Deployed at corporate campuses, residential societies, and commercial complexes nationwide.
Request a QuoteA QR code reader (also called a QR barcode scanner) is an optical scanning device that decodes a printed or mobile-displayed QR code to verify identity or authorise access. Unlike a card-based RFID reader, a QR reader needs no physical credential — a visitor pass, employee ID, or parking ticket can be issued digitally through an app, email, or SMS and scanned directly at the entry point.
In a typical QR-based access control setup, a unique code is generated for a person or vehicle. At the gate, the Novus QR reader scans and decodes the code in under 200 milliseconds and passes the result to a connected standalone or network controller over Wiegand, RS232, or RS485 — which then releases the door, turnstile, flap barrier, or boom barrier.
Novus currently manufactures two QR reader models: the NS-R400-QM, a compact IC-card and QR/1D-code reader for standard indoor access points, and the NS-R405-QM, a rugged EM/Mifare-card and QR/PDF417/full-symbology reader built for outdoor gates and higher-volume visitor or ticketing deployments.
Four QR reader models in the Novus catalogue — two current, two end-of-sale.
Two active models built for different access-control environments — from lobby entry points to outdoor, high-duty gates.
A compact QR & 1D barcode reader with IC card support — ideal for lobbies, office entrances, and standard indoor access points.
A rugged, weatherproof QR & full-symbology barcode reader with EM/Mifare card support — built for outdoor gates and high-volume visitor or ticketing deployments.
Every QR reader we manufacture is built for continuous entry-point use and supports the full spectrum of access control integrations.
Sub-200 millisecond scanning keeps entry lanes moving even at peak walk-in hours.
Reads QR codes alongside Code128, Code39, EAN-8, EAN-13, UPC-A and, on the NS-R405-QM, PDF417.
Wiegand, RS232, RS485 and UART outputs connect directly to Novus and third-party access controllers.
Operating ranges up to -30°C to 70°C and 90% humidity tolerance suit both indoor lobbies and outdoor gates.
Novus QR readers are deployed wherever a digital, card-free credential needs to trigger secure, fast entry.
A QR reader is only as useful as the ecosystem it plugs into. Novus QR readers are engineered to integrate directly with the controllers, barriers, and software already running your access control setup.
Whether you need a simple QR-triggered door release for an office lobby, or a full QR + RFID hybrid system feeding a centralised visitor and parking dashboard, Novus provides the reader hardware to make it work.

Key considerations before specifying a QR code reader for your access control project.
An RFID or proximity reader authenticates a physical card or tag held near the device — well suited to long-term employee or resident credentials that don't change often. A QR code reader instead scans a printed or on-screen code, so passes can be issued and revoked digitally without printing or collecting a card.
For visitor management, event entry, or parking ticketing where credentials are short-lived, a QR reader is usually the better fit. For permanent staff or resident access, RFID/Mifare credentials remain the norm — which is why the NS-R405-QM supports both QR/barcode scanning and EM/Mifare card reading on a single device.
Match the reader to where it will be mounted and how it will be used:
Documented Novus client projects where QR reader hardware has been supplied and installed.
Boom barrier, flap barrier, QR-cum-Mifare reader and access software deployed as an integrated entry system.
QR reader and access controller installed for project-wide vehicle and pedestrian access management.
QR reader deployment supporting commercial complex entry authentication.
Flap barrier, QR reader and controller combination for residential/commercial access control.
Swing barrier paired with QR-enabled facial recognition for a hybrid, multi-credential entry system.
Novus reader and access-control hardware — including QR, RFID and facial recognition systems — is deployed across premium real estate, government infrastructure, and Fortune 500 corporate campuses nationwide.
Access control hardware deployed across India's most prestigious residential and commercial developments.
Large IT campuses and corporate offices trust Novus for multi-lane, multi-credential access control.
Universities and institutional campuses rely on Novus for layered, credential-based entry systems.
