AI-powered QR code recognition for access control, logistics, production and shipping — integrated with camera infrastructure you already have. No contact required.
A camera reads the code. Metrici checks the database. The result fires instantly.
Any IP camera pointed at an entry point or production line captures the QR code — even at distance, at an angle, or in motion.
The engine decodes the QR in real time and cross-checks it against the Metrici database — access list, schedule, zone permissions and expiry.
Access is granted or denied in milliseconds. A barrier opens, a relay fires, a light turns green — or an alarm is raised for denied attempts.
Every scan is saved to the database with the decoded value, timestamp, camera, zone and a photo. Full audit trail at all times.
Scanning is just the start. Metrici QR Code Reader is a complete management platform.
Assign any number of access levels to each QR code. Control which zones, floors and time windows each code is valid for. Change or revoke with a single click.
Set validity windows per code: a visitor pass valid only from 09:00 to 17:00 on a specific date, or a contractor code that expires after three uses.
Generate new QR codes inside Metrici and send them by email or external service. No printing required — the recipient shows the code on their phone.
Trigger an alert when a QR code cannot be decoded, has expired, is blacklisted, or appears in a zone it is not authorised for.
Every scan event is saved with a timestamped photo of the code and its surroundings. Admissible evidence for any audit or investigation.
Filter all readings by code, zone, camera, time range and result. Export to XLS or PDF. Schedule automatic email reports.
Send every read event via HTTP POST to any external system — ERP, HR software, building management systems or custom dashboards.
A QR read can trigger another Metrici engine: match the code with a license plate, a face, or an ID simultaneously for multi-factor verification.
Runs on the IP camera infrastructure you already have. No dedicated scanner hardware, no new cabling, no installation downtime.
From a building entrance to a factory conveyor belt — wherever a code needs to be read and a decision made.
Contactless entry for employees, contractors and visitors. Each code carries its own zone and time permissions. Revoke instantly when needed.
Control access to restricted wards, pharmacies and data rooms. Issue time-limited codes to staff rotations and visiting personnel.
Student attendance via QR scan at classroom entry. Visitor management for parents, contractors and inspection teams.
Contactless check-in. QR room keys sent to guests before arrival. Combined with LPR for seamless vehicle access to the parking facility.
Strictly controlled visitor access with full log of every entry and exit. Blacklist management and automatic alert on unauthorised attempts.
Multi-layer access control for vaults, server rooms and restricted floors. Integrates with existing security systems via HTTP.
Scan QR codes on packages at each checkpoint. Know exactly where every shipment is in the chain, with timestamp and photo at each point.
Link a scanned package QR to the license plate of the vehicle loading it. Automatic cross-check for proof of correct dispatch.
Log every item arriving or leaving a dock. Verify codes against expected manifests and raise an alert for unexpected or missing items.
Scan on receipt confirms delivery with photo evidence. Exportable delivery log for billing, disputes and compliance documentation.
Read QR codes on containers, pallets or crates to log their position, status and chain-of-custody at every transfer point.
Combined with GPS or zone data, each scan records where in a facility or route a package was seen and when.
Read QR codes on components or assemblies as they move along a production line. Build a full history of every product’s journey through manufacturing.
Verify that the right component is at the right station. Raise an alarm if a mismatch is detected before it causes a defect downstream.
Track individual parts and assemblies from intake to final product. QR codes linked to service history, recall data and maintenance records.
Automatically read and log serial numbers from QR codes at high speed on a conveyor. No manual scanning, no missed items.
Track fabric rolls, garments or batches through different and finishing stages. Each QR tied to a production order and batch record.
Verify medication batches, dosage labels and expiry codes at every stage of dispensing. Alert on expired or mismatched codes.
Verify and keep track where ebery item is in a ware house. Automate inventory using drones with pre-established routes.
Scan e-tickets at entry gates. Validate, log and invalidate in one step. No paper, no dedicated scanner terminals, no queues.
High-throughput scanning at multiple entry points simultaneously. Full attendance log with time-stamped entry record per ticket.
Issue exhibitor, visitor and VIP codes with different access zones. Monitor attendance in real time from a single dashboard.
Send QR room keys to guests before arrival. Combined with LPR for vehicle access. Change or revoke keys remotely at any time.
QR-based table booking confirmation, staff access to kitchen areas and supplier delivery verification at the back door.
Digital boarding passes for buses, trains and private transport. Scan at the door, log the passenger, trigger departure checks automatically.
Metrici QR Reader is designed to work alongside other Metrici engines for powerful multi-factor verification at a single entry point.
A Metrici setup can simultaneously read a QR code, recognise a license plate and identify an ID. Metrici checks all three against its database and only opens the barrier when every condition is satisfied.
This makes it ideal for high-security environments where a stolen or shared QR code alone is not sufficient — the vehicle or the person must also match.
