I assume this is some kind of ACS reader, and those NFC readers usually
support a specific API for low level RF things, via SCardControl or
SCardTransmit, eg.
https://www.acs.com.hk/en/products/342/acr1252u-usb-nfc-reader-iii-nfc-forum-certified-reader/#tech-specs

PC/SC gives you a way to talk to a card (SCardTransmit) in a high-level
APDU oriented way and to talk to (vendor specific, proprietary, such as
libacsccid) readers with SCardControl. The rest is for you to figure out :)

Best,
Martin
