A data capture device includes: a primary housing supporting a data capture assembly and having inner and outer surfaces joined by a perimeter wall; and a mounting accessory coupled to the inner surface. The mounting accessory mounts the device on an operator index finger in either of: a side-mounted mode in which the primary housing is between the index finger and a thumb; and a top-mounted mode, in which the primary housing is on a back of the index finger. The device includes an accessory trigger on the mounting accessory and a primary trigger supported on the outer surface. In the top-mounted mode, the accessory trigger is between the index finger and the thumb, for activation by the thumb. In the side-mounted mode, the primary trigger is disposed on the side of the index finger for activation by the thumb of the operator.
