CLUSTER CARD-READERS-LIBRARY · 11 ENTRIES · EARLIEST ENTRY 2007-04-02

Card reader driver libraries

The cluster consists of drivers and libraries for various card reader hardware, enabling communication between software and smart cards, NFC, and FeliCa devices. The dated entries span from April 2007 to April 2026 with isolated releases in single months, indicating a sparse and intermittent development history. Traction is minimal, as the leading projects (abcccid, scmccid, lib32-ezusb) each have zero 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.
