About
A hardware integration studio, not a reseller
Asquarete is a hardware integration studio based in Hyderabad, India, working on a narrow problem: getting UHF RFID, barcode, and NFC hardware to run reliably in production on Android and .NET — not just in a vendor demo. The team is small and entirely engineering. We sell no hardware, so nothing here is written to move a device off a shelf.
The team
Asquarete runs as a single engineering team rather than a set of individual contractors. Every engagement is scoped by the founder, architected against the actual hardware, and reviewed before handover — so the work does not depend on one person staying reachable.
- Founder
- Client scoping, hardware feasibility, and final architecture review on every engagement.
- Senior Integration Architect
- Reader SDK architecture, EPC data models, and the boundary between device firmware and business systems.
- Android Engineers
- Kotlin handheld applications against Chainway, Zebra, and Sunmi SDKs — inventory loops, trigger handling, offline queues.
- Backend Engineers
- .NET and Python services, Odoo and ERP integration, idempotent ingestion of high-volume tag reads.
- Field & QA
- On-device validation: RF tuning, antenna placement, read-rate measurement, and failure reproduction on real hardware.

Why the guides exist
Every RFID and barcode vendor ships a tutorial. Almost none of them ship the part where the tutorial's own sample code breaks under real read rates, real tag densities, or a cold restart in the field. Zebra says as much directly: its own "Hello RFID" walkthrough states the demo app "is intended for tutorial purposes only and should not be used in production environments." Chainway's sample repositories call obsolete SDK methods their own changelog already deprecated.
These guides exist to close that gap — documenting the information vendors have but don't publish: which API calls actually hold up under load, which antenna placements produce false reads, and what a production-ready integration looks like once the tutorial ends. Every guide is written against a physical device, not a spec sheet.
