Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

JavaCard is the answer for smartcards. You can find example card software all over github, and you're looking for the JavaCard SDK from Oracle and GlobalPlatformPro to program them: https://github.com/martinpaljak/GlobalPlatformPro. There's even an ant task around somewhere that allows you to use ant tooling. Blank cards with "developer"/default keys can be picked up pretty much anywhere.
Buy blank cards, write your applet, test in an emulator if you want, push to card, test for real with your software that talks to the card, profit. Be aware that if your goal is to write custom cryptography implementations in Java on the Javacard, these will be prohibitively slow. No need to take my word for it, Niels Duif did exactly this: https://research.tue.nl/en/studentTheses/smart-card-implemen...

You then have to get the binary (CAP file) and use a tool like GlobalPlatformPro to install it. Hopefully your JavaCard has default authentication keys, otherwise you have to ask for this from whomever you bought it from.

Using a smart card to log in
Once you know you have a JavaCard, you need to find a FIDO applet to install it. A quick look finds one here but I can't say how good it is.
What are some alternatives?
IsoApplet - A Java Card PKI Applet aiming to be ISO 7816 compliant
FIDO2 - FIDO2 toolbox in Java and X-FIDO JavaCard applet
SatochipApplet - The open source hardware wallet smartcard - Satochip.io
yubikey-full-disk-encryption - Use YubiKey to unlock a LUKS partition
OpenSC - Open source smart card tools and middleware. PKCS#11/MiniDriver/Tokend
