  "faq": [
    {
      "question": "Can a single tag support both UHF and HF?",
      "answer": "Yes. Dual-frequency tags and cards contain both a UHF antenna/chip (typically NXP UCODE 9 or Impinj Monza R6-P) and an HF/NFC antenna/chip (typically NTAG 213/216 or MIFARE DESFire) in the same physical tag body. Typical applications are apparel that needs UHF supply-chain visibility and NFC consumer tap-to-verify, or hospital assets that need UHF location tracking plus HF tap-to-dispense. Proud Tek manufactures dual-frequency cards, labels and wristbands in volumes from 500 to 500,000 per order."
    },
    {
      "question": "Why does UHF frequency vary by country?",
      "answer": "UHF RFID operates in the 860-960 MHz band, but exact allocations differ by region due to local spectrum regulation. Europe (ETSI EN 302 208) allocates 865-868 MHz, North America (FCC Part 15.247) allocates 902-928 MHz, China (MIIT) allocates 920-925 MHz, Japan (ARIB STD-T106) allocates 916-924 MHz, Korea allocates 917-920 MHz, and much of Latin America follows FCC or ETSI. Modern UHF silicon (UCODE 9, Monza R6-P, Higgs-9) is broadband across the full 860-960 MHz range, so the same tag SKU works globally. But readers must match the regulatory band of the deployment country. HF at 13.56 MHz is internationally standardized with no regional variation."
    },
    {
      "question": "Which frequency is better for tracking items with liquids or metal?",
      "answer": "Neither frequency is ideal for direct contact with metal or liquid, but HF generally performs better on liquid (water absorbs UHF roughly 3-6 dB per cm at 915 MHz, but affects HF magnetic fields only marginally), and UHF generally performs better on metal when paired with a purpose-built on-metal tag that uses the metal surface as a ground plane (Confidex Ironside, Xerafy Data Trak, Proud Tek on-metal inlay). For tagging bottled chemicals, blood bags, saline, or wet laundry HF is often the cleaner choice; for tagging tools, IT racks, or metal containers UHF on-metal tags are the standard. Always pilot in the real environment before committing."
    },
    {
      "question": "Can an iPhone read a UHF Gen2 tag?",
      "answer": "No. Every iPhone since the iPhone 7 reads NFC (13.56 MHz ISO 14443 Type A/B) natively, but no Apple phone has ever shipped with a UHF Gen2 radio. Reading UHF from an iPhone requires an external Gen2 reader accessory (Socket Mobile DuraScan D785, TSL 1128) paired over Bluetooth, which is common in enterprise workflows but not in consumer use. The same is true of most Android phones. A small number of enterprise-focused Android handhelds (Unitech EA630, CipherLab RK25, Zebra TC22/TC27) ship with integrated UHF readers, but consumer Android phones read NFC only."
    },
    {
      "question": "If NFC is HF, does that mean all HF is NFC?",
      "answer": "No. NFC (Near Field Communication) is a specific subset of HF protocols defined by the NFC Forum, covering NFC Forum Types 1-5, built on top of ISO 14443 Type A/B and ISO 15693. HF includes additional protocols that are not NFC. ISO 15693 industrial vicinity tags, legacy proprietary 13.56 MHz systems, and certain RFID vicinity implementations used in libraries and laundries. In practical conversation, 'NFC' usually refers specifically to the smartphone-readable subset (NTAG, MIFARE DESFire NFC applications), while 'HF RFID' can mean either NFC or the broader ISO 15693 family."
    },
    {
      "question": "What is RAIN RFID and how does it relate to Gen2?",
      "answer": "RAIN RFID is the industry alliance and certification program for UHF Gen2, founded in 2014 by AIM, GS1, Impinj and NXP. The underlying air-interface protocol is EPCglobal Class 1 Generation 2 (EPC Gen2 v2), standardized as ISO/IEC 18000-63. 'RAIN' is essentially a brand for the ecosystem. When a tag or reader is labeled RAIN RFID, it means it conforms to the Gen2 v2 standard. Every modern UHF RFID deployment is RAIN / Gen2. The acronym comes from 'Radio frequency Identification' plus the cloud metaphor ('RF data floats in the air')."
    },
    {
      "question": "How do I pick between HF and UHF for asset tracking specifically?",
      "answer": "The asset-tracking decision usually turns on three questions: how many assets are in a reader field at once (UHF wins decisively when the number is more than five to ten per read), how far from the reader the assets are (HF is near-contact; UHF is meter-range), and whether you need bulk reads or intentional user-controlled reads (HF suits tap workflows; UHF suits portal and cycle-count workflows). We maintain a dedicated vertical comparison at /compare/hf-vs-uhf-rfid-for-asset-tracking/ with real deployment examples from hospital, IT and warehouse asset populations. For most modern multi-item asset tracking, UHF is the right default. But HF wins in dense item environments, on liquid-containing assets, and when operators strongly prefer intentional scanning."
