| 6. SMARTHealthLinkPayload.exp | |
| Definition | Optional. Number representing expiration time in Epoch seconds, as a hint to help the Health Link Receiving Application determine if this QR is stale. (Note: epoch times should be parsed into 64-bit numeric types.) |

| 8. SMARTHealthLinkPayload.flag | |
| Definition | Optional. String created by concatenating single-character flags in alphabetical order: 'L' indicates the Health Link is intended for long-term use and manifest content can evolve over time; 'P' indicates the Health Link requires a Passcode to resolves; and 'U' indicates the Health Link's url resolves to a single encrypted file accessible via GET, bypassing the manifest and SHALL NOT be used in combination with P. |
