<p>A touch-free dispenser includes a dispenser controller coupled to a memory unit, which includes a database of previously-stored vein patterns. A vein-pattern sensor maintained by the dispenser images the unique vein pattern of a user's hand without 5 contact. The imaged vein pattern is subsequently compared with stored vein patterns, such that if there is a match, the dispenser proceeds to dispense material, such as soap, from a refill container. Alternatively, if there is no match between the imaged vein pattern and the stored vein patterns, the dispenser enters a learn mode to allow the imaged vein pattern to be added to the database. Data associated with the use of the dispenser is also collected 10 during its operation, which is stored and associated with the imaged vein patterns for subsequent analysis.
