CLUSTER NFC-READS-ANDROID · 31 ENTRIES · EARLIEST ENTRY 2014-04-17

NFC card reading apps

This cluster consists of 26 NFC-focused utilities for reading, writing, and analyzing tags, cards, and smart credentials, including transit, meal, and ID cards. Dated entries from 2014 to 2026 each appear once per month in 20 different months, showing a sparse and fairly stable flow that gives no clear upslope or downslope. Among traction leaders, only paper-mono-nfc-image-transfer has measurable activity with 3 stars, while the other two named products sit at 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.
