Hey there! This is a great question! One way to do this is to use a ticket with deliverables. Once scanned, the vendor can check in each "credit" (deliverable) and then it would just be one code, instead of 50 different codes, or 10, or 20. Then, they can purchase as many bundles as they would like, but each "bundle" would just be 1 QR code to have in their inbox. There are a few other options, but that one might be the best solution for you to use. Note, that each vendor would need to have the Eventeny mobile app installed on their phone or device, and would need at least ticket scanning access to your event in order to redeem the tickets. If you'd like to learn more, I'd encourage you to reach out to our growth team to schedule a meeting and they can explain to you all of the options available.
