1. A method for associating a coin processing event on a coin processing machine with a user, comprising the acts of: receiving a user's first biometric input in a biometric input device operatively associated with the coin processing machine; storing the user's first biometric input in a computer-readable memory device; processing a batch of coins using the coin processing machine, the coin processing machine comprising a coin processing device configured to sort the batch of coins and determine a total value of the batch of coins; storing data relating to the batch of coins processed on the coin processing machine on the computer-readable memory device in association with the user's first biometric input; associating, in the computer-readable memory device, data relating to the batch of coins processed on the coin processing machine with the user's first biometric input; receiving a user's second biometric input in another biometric input device; storing the user's second biometric input in the computer-readable memory device: retrieving from the computer-readable memory device, using a processing device, the user's first biometric input in association with a redemption operation; comparing the retrieved biometric input, using the processing device, at a redemption location; and redeeming the value associated with the processed batch of coins responsive to a favorable comparison of the user's first biometric input and the user's second biometric input by the processing device.
