Various embodiments illustrated herein disclose a latching mechanism that enables engagement of modules on a mobile scanning device. The latching mechanism includes a release switch that translates between a first position and a second position. The release switch is coupled to a latch body that includes a first tongue section and a second tongue section. The first tongue section engages with the mobile scanning device, while the second tongue section engages with an attachment member. When the release switch is moved to a first position, the mobile scanning device is disengaged. When the release switch is moved to the second position, the attachment member is disengaged.
