A same-hand, finger-mounted, and finger-operated hand sanitizer dispensing system with finger-mounted or with remote-mounted fluid reservoir, is disclosed herein. The system is operable without risk of cross-contamination, and is operable by the contaminated hand for self-decontamination. A dispensing pump is mounted on one finger and operated by another finger on the same hand. The dispensing pump draws sanitizer from a reservoir by way of a supply tubing. The reservoir can be mounted on the same finger as the pump or on another finger of the same hand.
