RFID access kit
Access control
Golden rule: Explore for inspiration. Log in for progress. Purchase when you’re ready to commit.
No account needed to imagine your build
Scroll the catalog, open any path, and picture the outcome. Try a demo or workshop if you want more spark. Log in when you want checkpoints and saved progress. Buy the kit only when you’re committing to the build.
Tap a card → unlock or buzz. Uses standard MFRC522-style modules available from any maker store.
