Abstract
Abstract A wand which provides rapid contact to a two-terminal electronic token data module. The wand includes one contact which will make contact to the periphery of an electronic token which the wand is pressed against, and one contact which will make contact to the center of the token. Preferably the wand includes a base portion which is shaped to be worn on the second joint of a user's finger. This wand can be used for very rapid manual contacting of electronic tokens in various physical positions. This can be very advantageous in a variety of data collection/updating applications such as retail checkout, or tracking work-in-progress in a computer-assisted-manufacturing environment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
A wand for rapidly manually contacting two-terminal thin round electronic token data modules, comprising: a body of an nonconductive polymer material, including a base portion shaped to be firmly supported by the hand of a user, and a top portion extending from said base portion; said top portion including a surface positioned so that a user can bring said surface into contact with the token to be contacted, said surface including a recess therein which is shaped to mate with the token to be contacted, the inner perimeter of said recess being bordered by a conductive ring of conductive material, said ring of conductive material being connected to a first lead wire; an additional exposed contact, positioned substantially in the middle of said recess, said additional contact being connected to a second lead wire; whereby said first and second lead wires can be connected to a host computer to provide a data interface to randomly positioned tokens, as quickly as a user can make contact between said recess and the respective tokens.
Claim 2
Dependent Claim
172 words
A wand for rapidly manually contacting two-terminal thin round electronic token data modules, comprising: a body of an nonconductive polymer material, including a base portion shaped to be firmly supported by the hand of a user, and a top portion extending from said base portion; said top portion including a surface positioned so that a user can bring said surface into contact with the token to be contacted, said surface including a recess therein which is shaped to mate with the token to be contacted, the inner perimeter of said recess being bordered by a conductive ring of conductive material, said ring of conductive material being connected to a first lead wire; an additional exposed contact, positioned substantially in the middle of said recess, said additional contact being connected to a second lead wire; whereby said first and second lead wires can be connected to a host computer to provide a data interface to randomly positioned tokens, as quickly as a user can make contact between said recess and the respective tokens.
