How RFID should connect to a jewelry ERP or POS

Map the EPC or tag identifier to the retailer's SKU, serial number, certificate, order, location, employee, package, and transaction identifiers. Specify which identifier is encoded, where the cross-reference lives, and how duplicates or replacements are handled.

For each workflow, define the event name, required fields, source zone, time, operator or device, expected state, allowed transition, exception, and receiving system. A stocktake observation is not the same as a sale, and a read should not silently post inventory movement.

A device-adaptation layer isolates vendor protocols, firmware differences, commands, status, and capabilities. Middleware then applies read windows, deduplication, zone rules, task context, permissions, offline buffering, retries, monitoring, and event delivery.

This separation lets ERP, POS, WMS, or a jewelry management application consume stable events even when a reader or handheld model changes. It also creates one place to diagnose whether a problem began in RF capture, device control, event processing, or the business interface.

Use unique event or task IDs, idempotent receiving logic, acknowledgements, retry limits, dead-letter or exception queues, time synchronization, versioned payloads, and correlation logs. Define what happens when a store is offline, an ERP rejects an item, a transfer is partly read, or the same package is scanned twice.

Test permissions and data minimization. A device operator should receive only the commands and data required for the task, and the audit trail should show who initiated, confirmed, corrected, or cancelled a business event.
