I want to build an IoT RFID Machine Access Control system and I would like to know if anyone has suggestions or pros/cons of using the Particle system. The network would consist of 20+ endpoints with different users able to gain access to different machines/tools based on credentials.
In addition to granting access, I’d like the system to track who is using what and for how long. Ideally we’d use a mesh network, Power Relay Featherwings, and RFID readers such as the MFRC522. I’ve had success creating a crude prototype with Arduino, but I’d like to have a central database that can grant or deny access based on credentials. This could be a cloud-based platform or an on-site local server. Before I start ordering and spending money on things, does anyone have any useful insight or recommendations for me?
