Wooden transaction cards and methods of making the cards

Abstract

A wooden transaction card (WTC; smartcard (SC)) having several wooden layers (WL, SWL, PWL), reinforcement layers (RL) and adhesive layers (AL) and an in-card booster antenna circuit (BAC) incorporated in an adhesive layer of a core subassembly (CS). The wooden layers may be sliced or rotary peeled, preconditioned at the mill with a moisture content of 8%, and may be prepressed to a desired thickness. The reinforcement layers may comprise a substrate layer (SL) of nonwoven fabric and coated on one or both sides with an adhesive layer. The core subassembly (CS) is prelaminated to a defined thickness before final lamination involving a compression process of reducing the thickness of the stack-up of wood veneer, reinforcement and adhesive layers to an ISO conforming thickness of 760-800 μm, with pressure between 200 N/cm2 and 850 N/cm2 at a temperature between 135° C. and 150° C.
