Ticket verification

Anti-scalping ticket verification

Scalping thrives when tickets are bearer tokens anyone can resell without policy. AffixIO binds tickets to verification policy, enforces spent-proof at the gate, and returns signed allow or deny without copying attendee PII onto scanners.

Definition

Anti-scalping ticket verification uses policy-bound, spent-proof credentials so gates admit authorised presentations once under rules you define.

Field note. Tickets without spent-proof reappear on secondary markets minutes after first scan. Mark spent at verify, not at purchase.

Policy at issue and scan

Encode transfer and entry rules when minting. At the gate, verify signature and spent-proof. Allow or deny without a CRM lookup on the scanner.

Offline QR keeps entry moving when venue WAN fails. Sync Merkle audit later.

Venue operations

Train stewards on deny codes. Integrate with existing turnstile hardware via gateway verify where needed.

See offline tickets sector and anti-scalping resources for programme design.

Rollout notes for anti-scalping ticket gates

For anti-scalping ticket gates, provision sandbox circuits that mirror production predicates before you expose live agent traffic. Capture sample allow and deny payloads for regression tests.

Keep identity and rich attributes with the issuer. Verifiers receive outcomes and Merkle metadata only. Sync audit refs to your SIEM or order store after the gate returns.

NHI sprawl

Bearer tickets ignore transfer policy

If a ticket is just a code, resale markets ignore face-value and transfer rules. Venues need cryptographic policy at scan time.

Unlimited resale

Bearer codes circulate freely.

Double entry

Same code scanned twice without spent-proof.

PII at the door

Pulling attendee profiles to enforce rules creates new stores.

Verifier posture

Spent-proof tickets that survive resale markets

Anti-scalping controls need tickets that verify once at entry and cannot be replayed across resale chains. Spent-proof on first presentation with Merkle audit on the scan record closes the resale loop.

  1. Define transfer policy

    At mint time.

  2. Issue spent-proof tickets

    AffixIO credentials.

  3. Verify at turnstile

    Local or gateway.

  4. Audit with Merkle refs

    Post-event review.

Launch gates

Readiness checks for anti-scalping ticket gates

  • Replace bearer-only barcodes for controlled events.
  • Enable spent-proof on entry credentials.
  • Provision offline verify where WAN is weak.
  • Keep attendee PII off scanners.
  • Run double-scan tests before doors.

Security FAQ

Questions on anti-scalping ticket gates

Does this ban all resale?

Policy decides. AffixIO enforces the rules you encode.

Face matching required?

Not by AffixIO. That is a separate choice outside default verifier PII posture.
