Patent ID: 8188867

Claim:
A method for manufacturing a transponder inlay for a personal document, the method comprising the steps of: providing a chip module as part of the transponder, the chip module including a chip housing and a chip carrier, the chip carrier having a length larger than a length of the chip housing, the chip module having a thickness; providing a substrate as part of the personal document, the substrate being formed of a material that is permanently conformable by one of heat and compression, the substrate having a contact surface, the substrate having a thickness substantially equal to the thickness of the chip module; providing a stamping tool with a stamp tip at one end of the stamping tool, the stamp tip including a cutting edge, the cutting edge having a shape to cut a through-opening in the substrate, where the through-opening has a size corresponding to a size of the chip housing, the stamping tool also including a stamp collar spaced from the stamped tip, the stamp collar having a size corresponding to a size of the chip carrier; pressing the stamping tool against the contact surface of the substrate to cause the cutting edge to cut the through-opening in the substrate, said pressing also causing the stamp collar to create a permanent shoulder around the through-opening, said pressing being performed to space the shoulder from the contact surface by a thickness substantially equal to a thickness of the chip carrier; placing the chip module in the through-opening with the chip housing completely in the through-opening and with the chip carrier being adjacent the shoulder; providing a cover layer; arranging the cover layer on the contact surface of the substrate with the cover layer covering the chip module.
