POS Systems & Tessitura

We are looking for a point-of-sale system for concessions and merchandise sales that works seamlessly with Tessitura. We would like a system that could tie in with Tessitura in enabling reward and incentive programs, as well as tracking of sales in patrons' accounts.

Sample scenario:

- Tessitura generates a bar-code for inclusion in an e-blast or a printed coupon that could be scanned at the bar for 10% off a food item or drink and vice versa,

- when you purchase a drink or food items from the bar, logs those purchases into your Tessitura account history.

I suspect/realize that unless each patron gets a unique bar code for from one another within each offer, it may not be possible to track the usage of the discount to their acct, unless they use a credit card or agree to share an identifier like phone #, name, email address. BUT, at minimum I would expect to be able to track usage of each incentive for analysis and future strategic planning.

Is customization necessary?     Systems/software recommendations?

Thanks in advance!
