As for software, there are engines out there that do content-based image retrieval (CBIR) out of the box [1]. It should be possible to build something quickly in OpenCV. You may be able to get away using simple image template matching by putting a few constraints on how the camera sees each card. Something more robust can be also be build using image descriptors and approximate nearest neighbors, as in [2].

The data you cite has a large age group as well (0-69), which has the same problem you describe. See the comment by user kmm below for a reference with a better breakdown of estimated IFR by age groups. The reference also shows how the IFR increases exponentially by age.
If you want to see what number applies to you in particular, then you need an specific breakdown. But if you need to see what is the risk for the population in general, then the estimated total IFR, sampled from that same population, is valuable. Think of individual risk vs systemic risk.
Your reference is very good. It is still a pre-print, but the breakdown is very informative. It estimates the IFR (Table 4) for ages between 0-34 as 0.01% (1 in 10,000), increasing exponentially from there. The estimated IFR for the next age group, people between 34-54, is between 0.04% and 0.2% (1 in 2,500 to 1 in 500), one to two orders of magnitude greater. For people over 85, the IFR is 36.8% (~1 in 3).
Note that the population over 34 is about 50% of the total in the US.
>> Where's the data to back up any close to an assertion like this?
Latest IFR estimates are between 0.5% and 1.0% (1 in 200 to 1 in 100).

I guess in practice, for search purposes, we will see some kind of suffix attached to the name, Element Chat or similar.
