95% of visitors leave when forced into a monthly subscription. Passyn gives your business the programmable pass-issuing, dynamic QR rotation, and Stripe-settled checkout infrastructure to monetize short-term demand.

Day Pass
24 hours of full access. Built for gyms, coworking spaces, and digital publications converting visitors who will never subscribe monthly.
Exam Pass
Time-boxed access around the moment of need. Question banks, mock tests, and revision tools for the exact week that matters.
Project Pass
Two weeks of pro tooling for one deliverable. Let customers pay for the project window with usage limits and seat controls included.
Weekend Pass
Friday evening to Sunday night. Capture the high-intent weekend window your monthly subscription tiers were never designed to serve.
Edge Verification
One API call or optical QR scan to verify any pass in real time — expiry, usage counts, and revocation enforced centrally.
Signed Webhooks
pass.purchased, pass.activated, pass.expired — HMAC-signed, retried, and replayable so your systems always know who has access.
Integration Lifecycle
Three steps to your first verified pass. No date math, cron jobs, or custom entitlement tables required in your codebase.
STEP 01
Create a pass
Define duration, price, usage limits and branding in the merchant dashboard — or via one API call.
STEP 02
Customer buys it
Stripe-powered checkout, hosted or embedded. Passyn handles the split: your revenue, our transparent platform fee.
STEP 03
Verify access anywhere
Verify via REST or scan the dynamic QR pass at the door. Expiry, usage counting and revocation are enforced centrally.
