title: Restrict an NFC reader to only read cards with certain prefixes
body: <p>I'd like to know if I can limit what cards can be read with an NFC reader. Maybe with some kind of prefix on the cards, I could say e.g. "If the card doesn't start with 90H, reject it immediately."</p>
  
  <p>To be clear, I want to restrict access in a way where even if the reader itself was plugged into another computer, it still couldn't be used except with cards that I've encoded myself. Could this be done via a certain configuration to the reader? I'd really like to know if it's possible before I dive into my project.</p>
  
  <p>I'm using the ACR122U USB NFC reader with RFID cards. My goal is to use it with an online application to authenticate cards and grant access to certain services.</p>
