| Zusammenfassung: | An OTG anti-counterfeiting reader, comprising: a light-emitting circuit configured to output an optical signal to a to-be-detected object, the to-be-detected object generating a fluorescence signal under excitation of the optical signal; a receiving circuit configured to receive the fluorescence signal and convert same to a corresponding electrical signal; a control and identification circuit connected to the light-emitting circuit and the receiving circuit, and configured to control the light-emitting circuit to output or not to output the optical signal and obtain a result indicating whether the to-be-detected object is authentic according to the electrical signal; an interface conversion circuit connected to the control and identification circuit and a USB OTG interface, and configured to perform level conversion on data transmitted between the control and identification circuit and the USB OTG interface; and the USB OTG interface. The OTG anti-counterfeiting reader is able to provide a user with an easy a |
