    {
      "question": "What is the read range of a UHF RFID reader?",
      "answer": "A fixed UHF RFID reader (Impinj R700, Zebra FX9600, Alien F800 class) transmitting at +33 dBm EIRP into a 6-9 dBi circularly polarised antenna delivers 8-15 m read range on a modern Impinj M700/M800 or NXP UCODE 9 tag in free space. Real-world range drops to 3-8 m in warehouse, retail or dock-door environments because of metal racking, dense product stacking, liquid inventory and RF interference from adjacent readers. A handheld UHF reader (Zebra RFD40, Chainway C72) transmits at around +27-30 dBm with a smaller antenna and delivers 1-8 m. A desktop NFC reader (ACR122U class) is not a long-range device. It operates in the 13.56 MHz near field with 0-5 cm read distance by design."
    },
    {
      "question": "What's the difference between a fixed, handheld and desktop RFID reader?",
      "answer": "Form factor and job. Fixed readers are installed in a fixed location (dock door, conveyor, portal, overhead array) with external antennas and wired network + PoE, and are optimised for continuous high-throughput tag inventory. Handheld readers are battery-powered, roaming devices with an integrated antenna for cycle counts, audits and search-and-find. Desktop NFC/HF readers are short-range near-field devices for card issuance, personalisation, NDEF authoring and bench-top development. They do not read at range. Most real deployments use a combination: fixed for portals + handheld for audit + desktop for card issuance."
    },
    {
      "question": "Does an ACR122U read UHF RFID tags?",
      "answer": "No. An ACR122U is a 13.56 MHz HF / NFC reader (ISO 14443-A/B, ISO 15693, NFC Forum T1-T5). It reads NTAG21x, NTAG424 DNA, MIFARE Classic / Ultralight / DESFire / Plus, ICODE SLIX and phone-HCE credentials at 0-5 cm. It cannot read UHF RAIN (860-960 MHz) tags like UCODE 9 or Impinj M700 — for UHF you need a UHF reader (fixed or handheld). This confusion is the single most common RFID-reader purchasing mistake."
    },
    {
      "question": "What SDK do I integrate an RFID reader with?",
      "answer": "It depends on form factor and vendor. Fixed UHF: LLRP (ISO/IEC 19762) is the open standard and is supported by Impinj Octane, Zebra FX series, Alien, CAEN, Feig, Nordic ID. Use an LLRP library like LTK, OctaneSDK or sllurp. Impinj R700 additionally offers Octane IoT Device Interface (REST + MQTT) for cloud-native integrations. Zebra fixed + handheld can be driven by Zebra RFID SDK for Android / C / Java / .NET. Handheld: vendor Android SDK (Zebra RFD40 SDK, Chainway UHF SDK) plus Bluetooth SPP. Desktop NFC/HF: PC/SC + CCID (platform-native on Windows/macOS/Linux) or libnfc for the open-source stack. See [/guides/uhf-rfid-reader-api-guide/](/guides/uhf-rfid-reader-api-guide/) for code examples."
    },
    {
      "question": "How much does an RFID reader cost?",
      "answer": "Rough 2026 volume-pricing bands: a fixed UHF reader runs USD 900-2,500 for a 4- to 8-port enterprise SKU (R700, FX9600, Alien F800), plus USD 80-250 per antenna. A handheld UHF reader runs USD 1,200-3,500 for a modern sled-plus-terminal or integrated device (RFD40 + TC27, Chainway C72). A desktop NFC/HF encoder runs USD 30-150 (ACR122U near the entry, Omnikey 5022 / uTrust 3720F toward the top). Printer-encoder combos (Zebra ZT411R, SATO CL4NX-J RFID) run USD 2,000-4,000. Regional certification, spare antennas, PoE+ switches, mounting and site-survey labour are not included and typically add 30-60% to the reader BOM."
    },
    {
      "question": "Is a regional certification actually enforced on RFID readers?",
      "answer": "Yes. In the US the FCC requires Part 15.247 equipment authorization for every UHF RFID reader; in the EU the RED (Radio Equipment Directive) requires CE marking under ETSI EN 302 208 v3.3.1. Shipping a US-firmware R700 to a Frankfurt deployment is not a paperwork issue. The reader's frequency band (902-928 MHz) does not legally operate in the ETSI 865.6-867.6 MHz allocation and the device is subject to seizure on site inspection. Global SKUs from Impinj, Zebra, Alien and others ship in regional firmware images. Confirm the firmware matches the deployment country before shipping."
    },
    {
      "question": "Can one reader handle LF, HF and UHF tags?",
      "answer": "No single-radio reader does all three. The bands require physically different antennas, different RF front-ends and different air-interface protocols. A handful of multi-technology terminals (Identiv uTrust MD, HID Omnikey 5427 CK) combine HF + LF in one enclosure for access-control use cases. Multi-technology UHF + HF readers exist for library applications (Feig ID CPR74) but are the exception. For mixed-band deployments the normal architecture is two separate readers routed through the same host."
    },
    {
      "question": "How long does an RFID reader last in service?",
      "answer": "Fixed UHF readers are specified for 7-10 years of continuous service in indoor environments, assuming clean PoE power, -10 to +55 °C operating temperature and periodic firmware updates. Handheld UHF readers are typically 3-5 years in service before battery degradation and physical drop damage drive replacement. Desktop NFC encoders run 5-8 years. The practical life of a reader fleet is often set by firmware support. Most vendors drop support for a model 5-7 years after end of sale, which constrains security updates and SDK compatibility with newer card chips."
