Abstract
A payment product has a writing area (6c) which is intended for a user'"'"'s signature. In the writing area there is a first position-coding pattern (5) which makes possible digital recording of the signature. The first position-coding pattern is a subset of a larger second position-coding pattern.
The payment product is used in a payment system which is based on electronic payment information, which has been recorded by means of the position-coding pattern, being sent to a server unit, which utilizes the position-coding pattern to check that the payment information is valid.

36. A product comprising
an identification area provided with a user subset of an absolute position-coding pattern, which user subset codes coordinates and is assigned to a specific user enabling the specific user to identify himself by recording coordinates coded by said user subset.

49. A method of identifying a user of a product having an identification area provided with at least one subset of an absolute position-coding pattern, which codes coordinates, said method comprising
receiving coordinates recorded from the identification area, and, determining the coordinate area to which the coordinates belong and the user assigned to that coordinate area.
- 54. A system for identifying a user of a product, comprising a product having an identification area provided with a subset of an absolute position-coding pattern, which subset codes coordinates, and a computer having access to a data structure which associates a user with a coordinate area coded by the subset, and a device for recording coordinates from the product, wherein the computer is adapted to receive coordinates recorded by the device from the identification area on the product and to identify the user of the product by using the data structure and the coordinates received.
