Allow access from the internet http://bouncer.xinchejian.com/

Currently you need to be on Xinchejian Wi-Fi to be able to access bouncer. This requires people to enable Wi-Fi and wait for it to connect to the right Wi-Fi.

Note: when opening the door through the internet address, we can't use MAC to unlock.

We can however accept payments from Alipay/Wechat/PayPal and send a PIN.

Additionally you won't be able to stop people opening the door remotely..
One option is to use JavaScript geo location from mobile devices

OK, so opening the door is tricky, but we could accept electronic payments and this would always require a internet facing backend. The opened ports are unreliable, so there'd be a separate service running on some VPS, which the local VM can sync to once in a while. Or, "check local, if not found, check remote".

• Allow registering the payment over the internet; needs new QR code for http://bouncer.xinchejian.com/submit.html and a way for the local DB to sync with the cloud DB
• Change the door QR code to point to http://bouncer.xinchejian.com/ . Only allow opening the door from LAN, but show a message "Please connect to Wi-Fi" when accessed from internet.

These can be separate issues.

Part 1 "external payment" is actually easy, since the payment table is append only, so it's trivial to synchronize and merge with the one on LAN. Synchronization can happen daily and/or on request (for example, when the user tries to open the door, but the PIN is invalid.)
