IllegalArgumentException when using CLI

nic1v commented 1 year ago

Hello,

I'm receiving this IllegalArgumentException when running any command through Windows CLI...

Currently using this Reader/Writer + Card set but no FOBs though (https://dangerousthings.com/product/acr122u/)

Let me know if there is more information I can provide!

acr122 is one of the worst readers to use (many knockoffs and variations)
you get zero bytes of data from the reader for some reason. Can you try another card/another reader?
i suspect this is because you try to use GPPro with a Mifare card, which makes little sense. https://smartcard-atr.apdu.fr/parse?ATR=3B8F8001804F0CA000000306030001000000006A

Actually this can be improved to throw a meaningful exception when the reponse is less than 2 bytes in length.

Hello Martin! Thanks for the response.

I think the one card I was using was a Mifare card (Bought From Here)

I also tried this with a different card (NFC Ring actually) with the same response...

Is there a Reader/Writer you suggest? I'm currently trying to learn about this all to make an access control system for my house as a hobby so I appreciate any advice!

https://github.com/fidesmo/fdsm/wiki/Choosing-a-desktop-reader - from the affordable/chinese ones i prefer 1252 myself.

Try with your contactless bank card. The ring you are using is also Mifare classic, which has nothing to do with JavaCard-s
