V.A.L.E.T.

VisitAPI Automation & Location Estimation Terminal

V.A.L.E.T. serves to automate checking into the RC Hub when you walk in. It does this by reading WiFi packets that every device sends out when it connects to the Recurse Center WiFi network. If it sees any packets that were sent by a device whose MAC Address has been registered with it, it uses the Hub Visits API to create a new visit for the corresponding user.
