Barcode ticket to sms and interface with foxpro software

We have an interface to build website pages, and collect payments. What we require: • Tickets to be sent to a users mobile number with a barcode • Software to be able to scan barcode and interface with our software – write back to our software of who has been issued ticket onsite • Each day we need to scan the barcode in for delegates to access event • Each ticket is valid for a 3 day events – but can differ (need an option to amend)
