    {
      "question": "What should decide the first RFID reader shortlist?",
      "answer": "The first shortlist should come from the exact card or tag family, host environment and integration workflow the team needs to support rather than from the reader brand or enclosure style alone."
    },
    {
      "question": "Why do reader projects stall so often after purchase?",
      "answer": "They often stall because teams choose hardware before defining the software environment, the real credential set and the operating workflow the reader must support."
    },
    {
      "question": "Fixed vs handheld vs USB encoder — which form factor for what use case?",
      "answer": "Match the form factor to the workflow. Fixed reader (mounted at portal / dock door / shelf / conveyor / gate): unattended high-volume reading; vendors Impinj R700 + Zebra FX9600 + Honeywell IF61 + Alien ALR-9900+; cost $1.5K-$5K. Handheld (gun-grip Android UHF + barcode + camera): warehouse picking + retail audit + inventory walk; vendors Zebra MC3300xR + RFD40 + Honeywell CT60-XP + TSL 1128/1166 + Chainway C72; cost $1.5K-$3.5K. Smartphone sled (clip-on BLE-attached UHF): direct-store-delivery + field-service; vendors Zebra RFD90 + TSL 1153 + U-Grok-It; cost $1.5K-$3K. USB encoder (single-tag desktop): card issuance + kiosk encoding + sample testing; vendors ACS ACR122U + HID Omnikey 5022/5427 + Identiv uTrust; cost $50-$300. Integrated reader (embedded inside device): hotel lock + ATM + kiosk + POS; embedded per device. Most mid-large deployments use 2-3 form factors covering 90% of use cases."
    },
    {
      "question": "Which air interface should we pick — LF / HF / UHF / NFC / BLE / UWB?",
      "answer": "Match the interface to the read distance + security + smartphone-compatibility + environment. Security-critical short-range (door, payment, transit, hotel key, library): HF DESFire EV3 / iCLASS Seos / ICODE SLIX2 (13.56 MHz). Long-range item-level (supply chain, retail apparel, race timing, parking, vehicle, yard, asset): UHF Gen2v2 (860-960 MHz). Smartphone-tap consumer-facing (NFC business card, brand authentication, marketing): NFC (HF subset). Mobile credential + asset RTLS via existing Wi-Fi: BLE (2.4GHz). High-precision sub-meter location: UWB (3.1-10.6 GHz). Legacy estate maintenance: LF EM4100 / HID Prox (125 kHz) until refresh. Active long-range with battery (cold chain temperature logger, infant security): active 433MHz / 915MHz / 2.4GHz. Regional regulatory variation only matters for UHF (FCC 902-928 vs ETSI 865-867 etc.); HF + NFC are globally harmonised."
    },
    {
      "question": "Which protocol — LLRP / vendor SDK / PCSC / REST API / OSDP?",
      "answer": "Depends on form factor + integration depth. Fixed UHF readers: LLRP (vendor-neutral, supported by Impinj + Zebra + Honeywell + Alien) for portability; vendor-specific SDK (Impinj Octane, Zebra RFID SDK, Honeywell RFID SDK) for faster development with higher-level abstractions; REST API for cloud/modern integration. Desktop USB readers: PCSC (Personal Computer / Smart Card, ISO 7816-4) is the standard cross-platform protocol; PyScard for Python; libnfc + libfreefare for low-level on Linux. Access control readers: OSDP v2.2 (SIA + IEC 60839-11-5) is the new standard replacing legacy Wiegand, with AES-128 Secure Channel + bidirectional + firmware OTA. Mobile credential: HID Mobile Access SDK + Apple Wallet + Google Wallet SDK. High-throughput streaming: MQTT or Kafka for fleet event delivery to broker. Trading-partner visibility: EPCIS 2.0 (ISO/IEC 19987:2021). Library: SIP2 + NCIP. Start with vendor evaluation kit + SDK for proof-of-concept; migrate to LLRP or REST API for production where vendor-portability matters."
    },
    {
      "question": "How do we handle multi-region deployment — FCC / ETSI / IC / MIC?",
      "answer": "UHF requires regional reader SKU or multi-region tuneable firmware setting. US/Americas: FCC Part 15.247 (902-928 MHz, max 36 dBm EIRP / 4W ERP). EU/UK: ETSI EN 302 208 (865.6-867.6 MHz, max 2W ERP); CE/UKCA marking required. Canada: IC RSS-247 harmonised with FCC. Japan: MIC Article 2 (916.7-923.5 MHz, 2W ERP). Australia/NZ: ACMA Class Licence (920-926 MHz). Brazil: ANATEL (902-907.5 + 915-928 MHz). China: SRRC (920.5-924.5 MHz). India: WPC (865-867 MHz). South Korea: RRA (917-920.8 MHz). Major reader OEMs (Impinj R700 + Zebra FX9600 + Honeywell IF61) ship multi-region SKUs selectable via firmware setting. Tag chip cross-region compatibility: Impinj Monza R6-P + NXP UCODE 9 + Alien Higgs all work at all major UHF allocations 860-960 MHz, so a single global tag SKU is feasible. HF 13.56 MHz is globally harmonised — no regional issue. Dense-reader environments (large warehouse + airport) need LBT (EU Listen Before Talk) + DRM (Gen2v2 Dense Reader Mode) configuration during site commissioning."
