Each Chronocurl has a unique name (MAC address) that gets paired with your device via Bluetooth this means that no interference is possible from other Chronocurls being used in the arena. Bluetooth technology is been designed exactly to do that.
For the moment, only one Chronocurl needs to be handled by the software, but we have pretty awesome ideas about what we could do with a bunch working together, it will come sooner than later, keep watching!
