QR code attendance tracking apps

This cluster includes mobile and web applications that use QR-code scanning to record and track attendance for classrooms, events, and workplaces, with some adding role-based access, dashboards, or analytics. Entries appeared intermittently from April 2025 through July 2026, with monthly counts ranging from one to three, showing a steady but low-level introduction of new products. Among members with traction signals, Attendance-System leads with 2 stars, followed by Mark-d with 1 star and Presensi-magang with 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
