Abstract: A self-service kiosk includes a biometrics data input for inputting biometrics of a user of the kiosk, a reader for recovering biometrics data stored on a portable storage device such as an optical card, the portable storage device also containing information necessary to carry out a transaction, and a controller capable of comparing the input biometrics data with the stored biometrics data and authorizing a transaction based on a result of the comparison. Alternatively, or in addition to the above, the self-service kiosk may include a device for capturing an image of a customer/registrant, a biometrics capture device, and a data input device for enabling registration information to be entered and stored on a portable storage device such as an optical memory card together with the image and/or biometrics data, the portable storage device being dispensed to the customer/registrant immediately upon registration.
