Example implementations relate to a protective case with a barcode scanner. For example, the protective case may include a housing with a cavity to house a computing device. The housing may include a display portion to allow a screen of the computing device to be exposed, a back portion opposite the display portion, and a scanning sidewall perpendicular to and between the display portion and the back portion. The protective case may also include a barcode scanner to scan a barcode from the scanning sidewall.
