A bar code reader is an input Device. Although they sometimes output a visible light, the purpose is to gather data from a printed code and input that data into your system (computer, Point of Sale, etc.)
I expect you mean "Is Card reader/writer input or output?". If this is so, it is both an input and output device. Whenever you are trying to categorize a device as Input or Output, think of how it looks from the computer.If the computer is transmitting data to it, it is an Output device.If the computer is receiving data from it, it is an Input device.

A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
