Everything between your data and their wallet
Interlink Wallet takes care of the hard parts of wallet passes: cryptographic signing, device registration, push delivery, retries, platform rules and design quality. You keep ownership of the data and the relationship.
What they see is what is true
Your system stays the source of truth. Interlink Wallet never calculates balances or dates itself; it displays exactly what you send, formatted perfectly for each holder's language and currency.
- Money in pence, never floating point. Currency formatting for pounds, euros and dollars in UK, US, German and French styles.
- Dates in the holder's time zone, including friendly forms like "Tomorrow, 10:30".
- No-change detection. If nothing visible changed, nothing is sent, so holders are never disturbed for nothing.
What is ready today, and what is coming
We label everything honestly. "Available" means it is running in production today.
Sign-up certificate
AvailableOpening a sandbox asks for a certificate kept in the browser. One person receives one credit. A pass does not carry that certificate.
Live sync engine
AvailableEvents from your systems are resolved against your field map and every affected pass is updated, in one transaction, then delivered to devices. Stale updates are superseded automatically.
Apple Wallet passes
AvailableSigned passes in store card, event ticket, coupon and generic styles, with change messages on the lock screen and relevance dates for bookings.
Add-to-wallet links
AvailableSigned, expiring links for email, SMS and QR codes. Phones open Apple Wallet or Google Wallet, and other browsers see a branded preview with a QR code to hand over to a phone.
Notification policy
AvailableInstant or silent per template, quiet hours in your organisation's time zone and a daily cap that stays within platform limits.
Events API
AvailableScoped API keys, idempotency keys, clear error responses and a 256 KB limit per event. Built to be retried safely.
Tenant isolation
AvailableDatabase-enforced separation between organisations, per-tenant encryption keys and a tamper-evident audit log.
Google Wallet
AvailableGeneric pass classes and objects, short save links with no personal data in the URL, and lock-screen messages within Google's daily limits.
Pass Studio
In developmentA visual designer with pixel-accurate Apple and Google previews, stress-test data, version history and one-click rollback.
Analytics
PlannedIssued, installed, active and removed passes, update latency and notification reach, by template and brand.
Team, roles and SSO
PlannedOwner, admin, designer, developer, analyst and support roles, with single sign-on through your identity provider.
Bulk issuance
PlannedUpload a spreadsheet of holders and send passes in controlled batches without affecting anyone else's service.
Webhooks
PlannedSigned notifications when passes are installed, removed, scanned or redeemed, with retries and replay.
Every update arrives, exactly once
Updates are written to an outbox in the same database transaction as the change itself, so nothing is lost if a server restarts and nothing is sent for a change that did not happen.
- Automatic retries with increasing back-off when Apple or Google are busy.
- Newest wins. A late retry can never roll a pass back to an older value.
- Self-cleaning. Devices that have removed a pass are detected and dropped.
- Separated by organisation. Every delivery runs inside its own organisation's security context.
Transactional outbox
State and delivery intent commit together.
Back-off and review
Seven retries over several hours, then parked and audited for review.
Idempotent by design
Replayed events and duplicate calls are harmless.
Recorded
Every event, pass version and delivery attempt is kept.
One tap to add, from anywhere
Send a signed link by email or text, print a QR code, or add a button to your website. A phone opens Apple Wallet or Google Wallet. On a computer, people see a live preview of their own card and a QR code to finish on their phone.
- Links expire and are tied to one holder's pass.
- No tracking scripts and no third-party requests on the page.
- Your brand first, with Interlink Wallet only in the footer.
QR handoff
From desktop to phone in one scan.
Signed and expiring
Links cannot be guessed or extended.
Live preview
People see their real card before adding it.
