# 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
