MagSafe-Compatible Compact Barcode & 2D Code Reader (USB-C)

This is a compact barcode reader for smartphones built using the EV-DV007 CMOS barcode module.

It enables POS checkout and inventory management applications using only a smartphone.

Commercial products are mostly Bluetooth, and since there weren’t any that connected via USB-C, I built my own.

Because it uses USB-C instead of Bluetooth, it requires no setup and no charging, and provides low-latency, stable scanning.

Features

• Direct USB-C connection — No Bluetooth pairing or charging required
• MagSafe compatible — Magnetically attaches to the back of a smartphone
• Supports 1D/2D codes — Can read barcodes, QR codes, etc.
• 3D-printed case — A compact, portable original enclosure
