Use monospaced font to display certificate metadata #771

Open hardfalcon opened 2 years ago

hardfalcon commented 2 years ago

Please consider using a monospaced font to display the certificate metadata to make it easier to spot typos committed by the institution issuing the certificate. This is especially true since the paper printout you get issued when obtaining a new certificate a) uses a sans-serif font, which is the worst possible choice for this use case, and b) uses blue instead of black text, which results in grey text on the printout, which can be poorly rasterized depending on the exact printer configuration.

In my specific case, the institution issuing the certificate for my booster vaccination spelled my last name as "Emster" instead of "Ernster", and it took me a whole month to notice this (I had double-checked the spelling on the printout but didn't notice the mistake, and even though I had wondered why the third certificate showed up in CWA as if it had been issued to a different person, I attributed this to the fact that the vaccine used for my booster vaccination was not the same as the one used for my initial two vaccinations). I only found the culprit when I checked the certificate's Standardized Name, First Name field in the CWA, since all characters in this field are spelled in upper case.

You can probably even tell the advantage of monotype fonts for this use case when comparing the two in your browser:
