Tickets that
can't be
scammed.
Backdoor is the ticketing app for college social events. Every resale kills the old QR and issues a fresh one — a screenshot is a picture of a dead ticket.
How it works
Built so the scam can't happen.
Kill & reissue
When a ticket sells, the old QR dies and a fresh one is issued to the buyer. There is nothing to forward, nothing to fake, nothing to screenshot. The ticket you bought is the only one that scans.
Face value. Full stop.
Sellers get refunded at most what they paid. No markups, no bidding wars, no paying a stranger double for a formal ticket. Scalping isn't against the rules — it's impossible.
The line
Sold out? Get in line. When a ticket is released, it cascades to the front of the queue as a 15-minute offer at face value. Take it or it moves to the next person. No refresh-spamming, no DM lotteries.
The door
QR codes rotate every 30 seconds at check-in. Whatever is on someone else's screen expired half a minute ago. One ticket, one entry, no arguments at the door.
Trust tiers
Every ticket wears a shield.
Verified
Backdoor-issued · Full guarantee
Issued on Backdoor, held on Backdoor. We control the ticket record end to end — kill-and-reissue, face-value cap, rotating entry codes. If it doesn't scan, you get your money back. Guaranteed.
Protected
External tickets · Escrowed handoff
Tickets from outside platforms like Posh, traded through Backdoor. Verified .edu identity on both sides, payment held in escrow, and a structured handoff that doesn't release funds until the transfer is done.
For organizers
Run your door on Backdoor.
Frats, program boards, student orgs — sell out without the spreadsheet, the Venmo chaos, or the fakes at the door.
Issuance-grade tooling
Real ticketing, not a Google Form. Tiers, caps, and door scanning — free for student orgs.
Comp batches
Issue comps to brothers, boards, and VIPs in one shot. Every comp is a real ticket, not a name on a list.
Waitlist demand data
The line tells you exactly how many more people wanted in — so you know when to book the bigger venue.
The scam ends
at the door.
