CLUSTER CODES-SCANS-BARCODES · 13 ENTRIES · EARLIEST ENTRY 2022-04-16
QR/barcode scan and generate apps
This cluster consists of mobile apps that scan QR codes and barcodes, generate custom codes, and maintain a history of scans and creations; some also support sharing and exporting. Dated entries appear sporadically, with a single entry in each of nine distinct months spanning January 2011 to December 2025, reflecting a slow but continuous introduction of new products. All traction leaders show zero activity stars, so no single product leads.
Entry timeline
ENTRY TIMELINE
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.
