    {
      "question": "Does an ACR122U read UHF RFID tags?",
      "answer": "No. The ACR122U is a 13.56 MHz HF / NFC reader. It reads NTAG21x, NTAG424 DNA, MIFARE Classic / Ultralight / DESFire / Plus, ICODE SLIX2 and phone-HCE credentials at 0-5 cm near-field range. It cannot read UHF RAIN (860-960 MHz) tags like UCODE 9 or Impinj M700. For UHF reading you need a UHF reader. Fixed ([fixed UHF reader](/products/rfid-readers/fixed-uhf-rfid-reader/)) or handheld ([handheld UHF reader](/products/rfid-readers/handheld-uhf-rfid-reader/))."
    },
    {
      "question": "Do I need a driver for an ACR122U or Omnikey 5022?",
      "answer": "Not for basic operation. Both are PC/SC + CCID compliant and work with the built-in smart-card stack on Windows (WinSCard), macOS (CryptoTokenKit) and Linux (pcscd). Vendor-specific features — SAM slot access on ACR1252U, HID secure-mode on Omnikey 5022, MIFARE DESFire helpers on uTrust 3720F — require the vendor SDK, but the core 'read a card UID' and 'send an APDU' operations work with no driver install."
    },
    {
      "question": "Can a desktop NFC encoder write NTAG424 DNA SUN messages?",
      "answer": "Yes, with the right SDK. ACR1252U, Omnikey 5022, uTrust 3720F and uFR Classic all support the NTAG424 DNA command set (AuthenticateEV2First, WriteData, SetConfiguration) via vendor SDK or via NXP's TapLinx / NFC Reader Library. The SUN message is configured by writing the FileSettings with the SUN-enabled access condition, AES key and mirror configuration. See [/guides/ntag424-dna-sun-cmac-authentication/](/guides/ntag424-dna-sun-cmac-authentication/) for the full command sequence and reference implementation."
    },
    {
      "question": "What's the difference between ACR122U and ACR1252U?",
      "answer": "ACR1252U is the production-grade successor to ACR122U. It adds a SAM (Secure Access Module) slot for holding DESFire / Plus master keys securely, NFC Forum certification (some ACR122U SKUs are not formally certified), more robust USB firmware that handles rapid card-cycling better, and a slightly more capable MIFARE DESFire direct-command set. For development and low-volume use the ACR122U is fine; for production issuance bureaux the ACR1252U is the safer specification."
    },
    {
      "question": "Can I use these desktop readers with a Raspberry Pi or embedded Linux host?",
      "answer": "Yes. ACR122U, ACR1252U, uFR Nano, PN532 breakout and Omnikey 5022 all run on Raspberry Pi 3/4/5 and similar ARM Linux hosts via pcscd + libnfc. Many embedded deployments (self-service kiosks, access-control panels, custom encoders) use a Raspberry Pi Compute Module plus a PN532 or ACR122U. Power budget is typically 150-250 mA at 5 V USB."
