That makes drive-through testing a bit tricky!

Good point. That's why i reckon we should patent ‘anal recognition technology’.

We could become the next tech-whiz entrepreneur gazillionaires.

Here's how it could work (stop me if this is too much information):

I have a Japanese style toilet - seems more hygienic - just wanted it for the water - but modern ones sense you sitting down - make whirring noises - lights are activated. Freaks guests out a little bit but i'm used to it - find it comforting even.

How hard can it be to equip that existing setup with an anal recognition function?

We know Covid can be detected in sewerage - now you will be able to trace that all the way back to the actual arse-hole it came out of.
