“健康码”也是一种二维码，可以直接译为Health QR Code或直接译为Health Code。

可参考ChinaDaily的相关报道：

When entering the theme park, guests will be required to undergo a temperature check and present a green health code and a 48-hour negative nucleic acid test result.

参考译文：进入主题公园时，游客需接受体温检测，并出示绿色健康码和48小时核酸检测阴性结果。

However, destination airports may still require proof, and the Hefei airport will continue requiring arriving passengers to present health QR code and travel code before leaving the airport.

参考译文：不过，目的地机场可能仍需要证明，合肥机场将继续要求到达旅客在离开机场前出示健康码和行程码。

PS：顺便还学习了行程码的表达：travel code
