Frequently Asked Questions

What frequency does the P-4i operate on?

The Fixed Reader (P-4i) - 4 channels operates at 865–868 MHz (India/EU) / 902–928 MHz (US). India's UHF RFID allocation is the 865–867 MHz band, so confirm the regional variant when ordering — POXO supplies WPC/ETA-compliant units for Indian deployments.

What is the read range of the P-4i?

Published read range for the Fixed Reader (P-4i) - 4 channels is 25 m (ideal) (depends on external antenna gain & RFID tag, adjustable). Real-world range varies with tag type, antenna gain, mounting position, and nearby metal or liquids, so POXO validates read points on-site before go-live.

Is a software SDK available for the P-4i?

Yes — USB, Android / Windows Bluetooth, Android / iOS. Request access through the POXO Developer Zone and our integration team will supply the libraries and sample code for your platform.

How many antennas can I connect to a fixed RFID reader?

It depends on the model — integrated readers have a built-in antenna, while multi-port fixed readers connect several external antennas to cover dock doors, portals, or conveyor lines. Our engineers size the antenna count during the site survey.

Can this reader integrate with our ERP or WMS?

Yes. POXO fixed readers work with our middleware, which ships with SAP, Oracle, and Tally connectors plus REST APIs for custom systems, so read events post to your ERP in real time.
