  "faq": [
    {
      "question": "How do I identify the MIWA lock generation before ordering cards?",
      "answer": "Three indicators usually settle it: the visible model badge on the lock face (ALV2 Wide / Slim, ALV3M, ALV3MA, V3HTM or V3HTMA — MIWA prints these on the lock), the encoder model at the front desk (MIWA Card Issuing System with or without BLE option), and the version of the MIWA card-issuing software running on the front-desk PC. If all three are unclear, send a current guest card sample to the supplier for an inspection read before committing to a production chip."
    },
    {
      "question": "Can MIWA hotel locks read Japanese transit IC cards (Suica, PASMO, ICOCA) as guest credentials?",
      "answer": "Only the FeliCa-equipped MIWA models. PiACK II, PiACK III, VERSA-II and certain ALV2 firmware lines accept FeliCa IDm — which is how Japanese transit cards authenticate. ALV2, ALV3 and V3HTM in their default MIFARE-only mode do not read FeliCa. Properties that want transit-card guest credentials should confirm with MIWA service that the FeliCa antenna mode is enabled on the deployed reader heads, and validate transit cards on the actual lock before scaling."
    },
    {
      "question": "Does MIWA have any public security disclosures or CVEs?",
      "answer": "As of May 2026, the NIST National Vulnerability Database and cve.org have no public CVE entries for MIWA Lock Co. That is a favourable trust signal — particularly compared to the Saflok / Unsaflok disclosure of 2024 (CVE-2024-29916), the SALTO ProAccess SPACE 2019 CVE cluster, and the Onity HT-series 2012 Brocious disclosure. MIWA publishes a Security Statement page that documents its responsible-disclosure philosophy. Standard procurement diligence still applies — migrate any MIFARE Classic stock to DESFire EV2 / EV3 to retire the industry-wide Crypto-1 surface."
    },
    {
      "question": "Can I put MIFARE DESFire EV3 cards on a MIWA ALV2 estate?",
      "answer": "Only after a reader-head firmware update that extends chip support beyond MIFARE Classic. ALV2 was MIFARE Classic-first; DESFire support arrived on ALV3M / ALV3MA refreshes and is standard on V3HTM / V3HTMA. Two practical paths: a MIFARE Plus SKU during the migration window (Classic-compatible in SL1 mode, AES in SL3), or a phased reader-head firmware update before switching card stock. DESFire EV3 ships in EV2/EV1 backwards-compatible default, so an EV3 stock can serve an estate originally specified for EV2."
    },
    {
      "question": "What is the KEYMO mobile app and which MIWA locks does it work with?",
      "answer": "KEYMO is MIWA's first-party BLE mobile-key app for hotel deployments. It is available for iOS (16+) and Android (`com.miwa.alv2ble`). KEYMO requires either an ALV2 lock with the BLE option installed or an ALV3 / V3HTM lock with BLE built in. Properties that want mobile-key issuance without changing locks should specify the BLE option on the encoder and confirm KEYMO licensing with MIWA before guest rollout."
    },
    {
      "question": "Will premium-material cards (1.0 mm wood or bamboo) read reliably on MIWA?",
      "answer": "On ALV3M / ALV3MA and V3HTM / V3HTMA, yes — these reader heads are tuned for card stacks up to roughly 1.2 mm. ALV2 reader heads can be marginal at thicknesses above 0.9 mm given MIWA's already short authentication distance. Pilot a production-thickness sample on the actual lock model before ordering a full batch."
    },
    {
      "question": "What PMS systems are certified on MIWA?",
      "answer": "Oracle OPERA, Tap Co. (Japanese PMS), Temairazu (Japanese channel manager), RoomKeyPMS, Aavgo and a long tail of regional PMS platforms have published MIWA ALV2 / ALV3 card-issuing-system integrations. The limiting factor is usually the MIWA card-issuing software version on the front-desk PC, not the PMS itself. The Japanese-PMS coverage (Tap / Temairazu) is unusual and unique to MIWA — competitor platforms typically focus on western PMS only."
    },
    {
      "question": "Is the AL5H hybrid lock still a sensible procurement choice in 2026?",
      "answer": "Only as a migration tool for properties still running magstripe stock. The AL5H accepts both ISO/IEC 7811 magstripe and MIFARE Classic 1K / 4K on the same lock, which lets a property transition guest issuance from magstripe to RFID without replacing every lock at once. New estates should standardise on ALV3 or V3HTM for an RFID-only path; the AL5H's 15-20 second IR programming workflow and magstripe maintenance burden make it costlier per lock over a multi-year horizon."
