Ably Masterclass | Episode 2 - Building an IoT based realtime attendance system for Slack

What's this blog post about?

In the second episode of a masterclass series, the speaker discussed building an RFID-based access card scanner that publishes messages directly into a Slack channel. The session covered topics such as MQTT, Webhooks, and IoT components. A detailed tutorial is available online for those interested in building this app themselves. The full application was demonstrated at the end of the masterclass, showing how an access card placed near the RFID reader would trigger a Slack message. Useful resources from this masterclass episode include recorded video, presentation slides, a written tutorial, GitHub repo with full source code, and Ably Reactor integration docs. The next episode in the series will be announced soon.
