1. A method for controlling access to goods or services, the method comprising:
- reading at least one absolute location from an encoded base;
checking if the location is within a region belonging to an authorized user; and
granting access by the authorized user to the goods or services if the location is within the region belonging to the authorized user, otherwise denying access; and
wherein reading said at least one absolute location from the encoded base includes recording a pattern from the base with an optically imaging pen, and converting the recorded pattern into a location.

Abstract
A system and method are disclosed for controlling access to goods or services. A location may be read from a base, such as a card, using a digital pen. The system may then check if the location is within a region belonging to an authorized user. If so, access may be granted to the authorized user to the good or services.

8. A system for controlling a user'"'"'s access to goods or service, comprising:
-
a sensing device for reading at least one absolute location; and a checking device which determines whether the at least one location is associated with at least one region belonging to an authorized user for authorizing access to the goods or service, and providing an enabling signal when the checking device determines that access is authorized, wherein the sensing device is further operable to read a sequence of locations which describe movement of the sensing device when a user is writing with the sensing device. - View Dependent Claims (9, 10, 11, 12)

13. A base for controlling access to goods or services comprising:
-
a substrate; a writing field associated with the substrate; and a position coding pattern associated with the writing field, wherein the position coding pattern encodes at least one absolute location used to grant access authorization, whereby the position coding pattern is read during movement of a sensing device over the writing field, and wherein the sensing device is configured to convert the position coding pattern to the at least one location. - View Dependent Claims (14)
