  "faq": [
    {
      "question": "How do I link RFID tags to Shopify product variants?",
      "answer": "The preferred method is to encode tags with an SGTIN-96 value derived from your GS1 Company Prefix and the GTIN stored in the variant's barcode field on Shopify. The RFID middleware extracts the GTIN from the EPC and queries Shopify's Admin API to resolve the matching variant. For merchants without GS1 Company Prefixes (common for DTC brands), an alternative is to encode the Shopify variant SKU into the tag's user memory or use a custom EPC scheme with the variant ID; middleware resolution is then a direct SKU or variant ID lookup. Proud Tek pre-encodes tags based on a Shopify variant CSV the customer provides, returning a TID-to-variant mapping file that imports into the chosen middleware or Shopify app."
    },
    {
      "question": "Do I need to tag every item for Shopify RFID integration?",
      "answer": "For accurate inventory sync, yes. Every physical unit that should appear in Shopify inventory counts must carry an RFID tag. Untagged items are invisible to the RFID read and will show as zero stock. The most cost-effective operational pattern is source tagging (supplier applies tags before shipping to your warehouse or 3PL) so that incoming inventory is already RFID-ready. For existing untagged stock, a one-time backfill tagging pass at the warehouse gets you to steady state; after that, source-tagged new arrivals eliminate ongoing tagging labour. Proud Tek can coordinate tag shipments directly to your suppliers for source-tagging workflows."
    },
    {
      "question": "What RFID readers work with Shopify?",
      "answer": "Shopify doesn't connect directly to RFID readers. The integration runs through a middleware app (from the Shopify App Store or a third-party platform) that speaks to the reader via its native protocol and to Shopify via the Admin REST or GraphQL API. Common reader choices for Shopify merchants include Zebra MC3330xR (handheld Android), Chainway C72 (Android-based handheld), TSL 1166 Bluetooth UHF reader (pairs with iPad / iPhone / Android), and Nordic ID Stix. For fixed deployment (overhead readers, dock portals), Zebra FX9600 and Impinj Speedway R420 are common enterprise choices typically managed through a general RFID middleware platform rather than a Shopify-specific app."
    },
    {
      "question": "Can Shopify POS work with RFID for in-store inventory counts and returns?",
      "answer": "Yes. Shopify POS is an iOS / Android app that runs at each physical store; store associates can pair a Bluetooth RFID handheld (like the TSL 1166) to the POS device and use a companion app (from the App Store or custom-built) to perform RFID counts, receive transfer orders from the warehouse, validate returns at the counter and perform zone-by-zone cycle counts. The RFID-driven inventory updates propagate through Shopify's multi-location inventory to the online store, other POS locations, and connected marketplace channels. Retailers with omnichannel fulfillment (endless aisle, buy-online-pickup-in-store, ship-from-store) rely on RFID-accurate store inventory to make fulfillment routing reliable."
    },
    {
      "question": "How do I handle multi-location inventory with RFID on Shopify?",
      "answer": "Shopify's multi-location inventory model is directly compatible with RFID. Each physical location (warehouse, store, 3PL, drop-ship partner) is a Shopify location with its own inventory levels. RFID counts at each physical location update the corresponding Shopify location through the middleware, which scopes inventory adjustments to the reader's location ID. Shopify Plus supports unlimited locations; non-Plus plans support up to 10 (sufficient for most DTC brands and mid-size omnichannel retailers). For Plus merchants with global operations, Shopify Markets additionally enables per-market inventory and pricing while still sharing the underlying inventory pool."
    },
    {
      "question": "Will RFID integration work if we use a 3PL or fulfillment partner?",
      "answer": "Yes, with the 3PL's participation. If the 3PL already runs their own RFID programme, they typically expose inventory updates via EDI or their own API; a middleware like Celigo, MESA or a custom integration translates 3PL inventory events into Shopify inventory adjustments. If your 3PL doesn't run RFID yet, some will accept a customer-provided RFID infrastructure (readers installed at your allocated slot in their facility, managed by your middleware), while others prefer standardized processes across all their customers. We recommend confirming 3PL support early in the programme design; Proud Tek has experience coordinating source-tagged shipments directly to customer 3PL partners."
    },
    {
      "question": "Do I have to use the GraphQL Admin API or can I keep building on REST?",
      "answer": "For new integrations, GraphQL is effectively required. Per Shopify's deprecation timeline, the REST Admin API became a legacy API on October 1, 2024, and from April 1, 2025 all new public apps in the Shopify App Store must be built exclusively on the GraphQL Admin API. Existing REST-based middleware continues to work, but new development should use GraphQL. The current API version is `2026-01` (with `2026-04` next), and inventory mutations gain a required `@idempotent(key:)` directive in `2026-04` — pin to a specific version, plan a quarterly upgrade cadence, and migrate your inventory writes to GraphQL `inventoryAdjustQuantities` and `inventorySetQuantities` (which replaces the deprecated `inventorySetOnHandQuantities`)."
    },
    {
      "question": "How do I avoid double-posting RFID counts when the network drops mid-mutation?",
      "answer": "Use Shopify's idempotency directive on the GraphQL inventory mutations. As of API version `2026-01`, `inventoryAdjustQuantities` and `inventorySetQuantities` accept `@idempotent(key: $idempotencyKey)` where the key is a stable string per logical RFID count batch (a UUIDv4 derived from reader-ID + UTC timestamp + sequence number works well). If the same key is replayed with the same input, Shopify returns the original successful result; if replayed with different input, the mutation returns `IDEMPOTENCY_KEY_REUSED_WITH_DIFFERENT_INPUT` so your middleware can flag a logic bug instead of silently corrupting stock. From version `2026-04` the directive is required, not optional."
    },
    {
      "question": "What does a Shopify RFID programme typically cost at DTC or Plus-merchant scale?",
      "answer": "Programme cost has three components: tags (variable by SKU count and volume, typically a few cents per UHF label for retail apparel volumes), reader hardware (handhelds from USD 1,000-3,000 each, fixed portal infrastructure USD 5,000-15,000 per dock door, scaling with location count), and middleware / app subscription (App Store apps from USD 50-500/month depending on features; enterprise middleware platforms scale to thousands/month). For a DTC brand with one warehouse, a meaningful programme might start at USD 5,000-15,000 upfront plus USD 100-500/month ongoing. For a Shopify Plus retailer with multiple stores, costs scale with location count but so does the ROI from overselling reduction and fulfillment accuracy improvements. Proud Tek can provide tag-cost estimates alongside third-party hardware and software budgeting guidance as part of the sample-pass conversation."
