The QR Code Time Clock That Stops Buddy Punching
A single-use QR code that refreshes at short intervals — impossible to fake. Contactless clock in and clock out from any phone.
Fingerprint scanners are expensive, raise hygiene concerns, and create privacy headaches. Badge systems get lost, shared, and passed around. QRAY replaces all of it with a dynamic QR code that rotates at short intervals. Employees open the QRAY app, scan the code displayed at your location, and they are clocked in or out in seconds. Because the code changes constantly, a screenshot is worthless seconds later — buddy punching simply stops working.
How the Dynamic QR Code Works
A tablet, phone, or computer at your workplace shows a QR code that automatically refreshes at short intervals (about every 25 seconds by default); each code is signed by the server, time-limited, and single-use. Employees open the QRAY mobile app, point their camera at the screen, and the punch is recorded instantly with a timestamp. The whole thing takes seconds and requires no contact, no PIN sharing, and no dedicated terminal. Each code works only once and expires within 30 seconds, so a scanned code cannot be reused.
Why a Rotating Code Beats a Static One
A static QR code is just a fixed string anyone can photograph and reuse from home. A rotating code is time-stamped and signed, so it can only be scanned in person, in the moment. Where you also need location proof, QRAY's fixed QR code and one-tap clock-in add GPS verification on top.
Hardware-Free by Design
Biometric clocks mean buying dedicated hardware and storing sensitive data you then have to protect. Card readers add ongoing badge costs. QRAY needs none of it — any device you already own becomes the time clock, and the only thing employees carry is the phone already in their pocket. Roll out a new location in minutes instead of waiting on hardware shipping.

Frequently Asked Questions
Our team is ready to answer your questions over WhatsApp and email.
Can the QR code be copied or shared?
Each code is single-use: once scanned, it cannot be used again, and an unused code expires within 30 seconds. Where you need location proof, fixed QR codes and one-tap clock-in also check the employee's GPS position.
Do employees need their own phones?
Yes, each employee installs the free QRAY app on their phone. For team members without a smartphone, managers can record clock-ins and clock-outs manually from the admin panel.
What happens if the internet goes down?
Clock-ins require an internet connection. The live QR screen needs to be online, and the employee's phone needs internet access to record a punch.
