ZSI-QR803D — frequently asked questions
What barcode types does the ZSI-QR803D support?
It reads all common 1D symbologies (UPC/EAN, Code 128, Code 39, Interleaved 2 of 5, GS1 DataBar and more) and 2D codes including QR Code, Micro QR, Data Matrix, PDF417 and Aztec.
Do you support OEM customization on the ZSI-QR803D?
Yes. As the manufacturer we support enclosure branding, interface and firmware configuration, and module-level customization. MOQ starts from 1 unit.
What warranty applies to the ZSI-QR803D?
All ZSI products carry a 24-month warranty from the shipment date, with free accessory replacement within the warranty period and 7×24 technical support.
What is the difference between the bare engine and the development board version?
The bare 21.5 × 14.5 × 10 mm engine (2 g) is for direct integration where you design your own carrier PCB and cabling. The development board version (44 × 33 × 11 mm, 10 g) adds a ready-made carrier with connectors for faster prototyping.
Is the ZSI-QR803D suitable for battery-powered devices?
Yes. It works at DC 3.3 V or 5 V and draws only 150 mA while working and 70 mA in stand-by, which suits handheld and portable equipment.
