This Electronic Visit Verification utility generates and checks time-based OTP values used by compatible EVV systems. Configure the shared secret, time period, visit date, and IANA time zone to reproduce device output while accounting for daylight-saving transitions.
Values are calculated locally and are not submitted to a server. EVV requirements vary by platform and jurisdiction, so confirm the exact algorithm and enrollment rules required by the target system. For generic time-based testing, see the TOTP generator.
