Patent Images
1. A business card reader connected to at least one of two external electronic devices, the business card reader comprising:
- a scanning module; and
a transmission module having a first USB port and a second USB port connected to the two external electronic devices, respectively, and a USB detecting/switching unit connected between the scanning module and the two USB ports;
when only one external electronic device is connected to the business card reader, the USB detecting/switching unit provides a data transmission path for the scanning module and the connected external electronic device;
when both two external electronic devices are connected to the business card reader, the USB detecting/switching unit can selectively perform a data synchronization mode for the two external electronic devices or at least one data transmission mode.
