Yes, it's a ref specific to this parking lot to be entered into an app or sms. 

But I just realized that I'm also not sure how to enter this payment method. payment:sms is documented in the wiki but how should we enter payment via an app? payment:mobile_payment? payment:app?

And maybe the ref should then be more like

ref:payment:app=12345
ref:payment:sms=12345
