MAC addresses won't be good for some Android devices and any Apple iOS device running iOS 8.0 or later. Some Android devices and all iOS 8 devices randomize their Wi-Fi interface MAC addresses during polls.
You could do Bluetooth, but some percentage will have it turned off. Since this is a voluntary deal, you could just have them turn Bluetooth on when they want to be tracked and run periodic scans.
Trivia: I once ran something like this when I lived next door to a prostitute and was able to track her customer arrival and departure times (along with BT MACs, device names, etc).
