Dynamic QR Code Recognition Swing Gate Turnstile With Anti Screenshot Offline Validation

Product Description

This swing gate turnstile is built around a dynamic QR code recognition terminal for office lobbies , campus buildings , serviced apartments , fitness clubs and event venues that issue passes online . The QR code is generated by the operator ‘ s own app , mini program , email or ticketing platform and can be set to refresh automatically every few seconds , so a screenshot forwarded to another person is rejected the moment it reaches the gate . The scanner reads a code from a phone screen , a printed ticket or a wearable band in about 0.3 seconds , at any screen brightness , and releases the acrylic swing arm without the visitor breaking stride . When the network drops , the controller keeps validating against a local white list that is synchronised in advance , so a failed cable or a busy mobile network does not stop the queue at the entrance . Every pass is written to the controller and uploaded when the link is restored , together with the direction of travel , the credential type and a snapshot of any rejected attempt . Access rights are issued , suspended , renewed or revoked in the backend in real time , which makes one time visitor codes , contractor codes , day passes and monthly passes easy to separate . The lane is fitted with four pairs of infrared sensors for anti tailgating , an audible and visual alarm for unauthorised entry , and an anti pinch mechanism that rebounds with a force not exceeding 2 kg . The frame is 304 stainless steel or 201 stainless steel with baked paint , the barrier is acrylic , the mechanism is rated for more than 5 million cycles , and the unit works from -30 C to 70 C at IP43 or IP54 , indoors or under a canopy outdoors .

Features and Advantages

1 . Dynamic QR code with anti screenshot protection

The entry code refreshes on a short cycle and is bound to the visitor account . A screenshot , a forwarded image or a reused code from an earlier visit is refused by the gate , which closes the most common loophole in QR based ticketing .

2 . 0.3 second recognition at any screen brightness

The scanner reads QR codes from phone screens , printed tickets and wearable bands in about 0.3 seconds . Visitors do not need to open an app , adjust brightness or stop walking , and the lane handles 30 people per minute , or 40 people per minute in normally open mode .

3 . Offline validation keeps the lane running

A synchronised local white list lets the controller verify codes even when the network or the server is unavailable . Passes are stored on the device and uploaded automatically when the connection returns , so entrance management never depends on a stable internet line .

4 . Self service code issuance and real time control

Operators issue , suspend , renew or revoke codes from the backend or the app . One time visitor codes , contractor codes , day passes and period passes are managed in the same system , and front desk staff no longer need to check tickets by hand .

5 . Full entry records and rejected attempt snapshots

Each passage is logged with time , direction , credential type and lane number , while rejected attempts are stored with a snapshot . Managers can review traffic peaks , tailgating attempts and abnormal entries from a phone or a PC .

6 . Anti tailgating , alarm and gentle anti pinch

Four pairs of infrared sensors cover the whole channel and detect a second person following a valid entry . An audible and visual alarm is triggered on unauthorised entry , and the swing arm rebounds with a force not exceeding 2 kg when it meets resistance , protecting visitors and children .

Frequently Asked Questions

1. What stops one visitor from sharing a QR code screenshot with someone else?

The code is dynamic and tied to the visitor account. It refreshes on a short cycle and each code can only be used once, so a forwarded screenshot or an old code is rejected and the attempt is recorded.

2. Does the gate still work when the network or the server is down?

Yes. A local white list is synchronised to the controller in advance, so valid codes continue to open the gate. Passage records are cached on the device and uploaded once the connection is restored.

3. Which code formats can the scanner read?

The terminal reads QR codes and barcodes displayed on phone screens, printed on paper tickets, or carried on wristbands. It also accepts RFID and IC cards, facial recognition and password entry on the same lane.

4. Can it be connected to our own ticketing or visitor management platform?

Yes. The controller provides relay switch, 12V level and 12V pulse interfaces with pulse width above 100ms, and supports RS485 or TCP IP communication, so it can be integrated with most ticketing, visitor and membership platforms.

5. Is it suitable for outdoor entrances?

The standard unit runs from -30 C to 70 C with IP43 or IP54 protection and can be installed indoors or in a covered outdoor area. A rain canopy is recommended for fully exposed locations.
