A barcode scanner magnetically attachable to a smart phone includes a circuitry adaptor and a barcode-scanning device. The circuitry adaptor is plugged into a USB connector of the smart phone. The barcode-scanning device is magnetically and detachably connected to the circuitry adaptor, so that electricity and signals from the smart phone are transmitted to the barcode-scanning device, and barcode signals picked up by the barcode-scanning device are transmitted to the smart phone. When the barcode-scanning device undergoes external impact, the circuitry adaptor and the barcode-scanning device are detached from each other without damaging the USB connectors.
