Last updated: June 24, 2026
Quick answer
Apple/TSYS UAT outages happen. Check status.koard.com for known outages before deep debugging.
Symptoms
- Enrollment failing — UAT vs production
Solution
The enrollment process is the same across environments, but the SDK must be configured for the correct environment:
- iOS: Confirm a supported physical iPhone, Developer Mode enabled, and a Sandbox Apple Account signed in for UAT. Restart the device and retry if enrollment fails.
- Android: Disable developer mode before running Tap to Pay transactions (required security control).
- If UAT worked but production fails, unenroll and retry against production.
