TRBO + Loading Constituent via Scan

#REPOST from Admin/IT

Good afternoon,

We are thinking about moving our concessions to TRBO come September and the v15.1 release (hello, cash payments!). I have an idea of which I don't know if it's even possible. I would LOVE your thoughts as to how the following could/would be setup:

I would like to create a barcode on either a custom ticket header and/or a membership card that simply loads a constituent ID into TRBO. Through pricing rules and/or offers, our member discounts would automatically be applied to the price types/items by way of constituency. A few questions for the Tessitura interwebs:

1. Is this possible?
2. Would this be possible by having the ticket barcode work double-duty through NSCAN?
3. If not the ticket barcode, another barcode using NSCAN?
4. If not NSCAN (as I understand that scan is encrypted and may add unnecessary characters to the barcode number), what scanner(s) could we use?
5. How would the scan speak to Tessitura? 

I would love to hear from anyone who's done something similar and/or knows more about this than I do (that probably includes most of you).

THANK YOU!
