I work for a small business that wants to start giving away gift certificates for a free service. Unfortunately we have 12 stores, so we need a way for the stores to be able to validate the gift certificate so that we dont give away this service multiple times. Looking for a script I can install on the server that when someone comes in with a gift certificate 1 or 2 years from now, it can still be used. Heres the process. We send through email a printable gift certificate. On it is a Alphanumeric (or just numeric code). The person prints it and takes it to the store. The store takes the certificate and goes online to www.whatever.com/certificate and types in the code on the certificate. if it is not used, then it is to show available. the store can then login and mark the certificate as void, and put the date it was voided. Now if that code is used again it will show that it was used previously at x date (and better yet, if it has custom fields, then also at x store). Is there anything like this out there? preferably free? and if not this sounds pretty easy to make, the only issue is that I am not a coder any help is appreciated!
