In some approaches, a transaction card may include a body having a first outer layer opposite a second outer layer, and a corrugated core between the first outer layer and the second outer layer, wherein the corrugated core comprises a plurality of alternating peaks and valleys coupled to the first outer layer and the second outer layer. The transaction card may further include an identification chip positioned through the first outer layer, wherein the identification chip is directly coupled to the corrugated core. ## Claims ### Claim 1 A transaction card, comprising: a body comprising a first outer layer opposite a second outer layer; and a corrugated core between the first outer layer and the second outer layer, wherein the corrugated core comprises a plurality of alternating peaks and valleys directly coupled to the first outer layer and to the second outer layer; and an identification chip positioned in an opening of the first outer layer, wherein the identification chip is directly coupled to the corrugated core, and wherein a first dimension of one or more peaks in a subsection of the corrugated core directly coupled with the identification chip is different from a second dimension of one or more peaks in a remainder of the corrugated core. ### Claim 2 (depends on 1) The transaction card of claim 1, wherein the first outer layer is made from a first material and the corrugated core is made from a second material. ### Claim 3 (depends on 2) The transaction card of claim 2, wherein the first material is different than the second material. ### Claim 4 (depends on 3) The transaction card of claim 3, wherein the first material is a metal and wherein the second material is a plastic polymer. ### Claim 5 (depends on 2) The transaction card of claim 2, further comprising a magnetic stripe extending along the second outer layer of the body. ### Claim 6 (depends on 1) The transaction card of claim 1, wherein the body defines an outer perimeter including a first end opposite a second end, and a first side opposite a second side, and wherein the corrugated core extends between the first and second ends. ### Claim 7 (depends on 6) The transaction card of claim 6, wherein the corrugated core further extends between the first and second sides. ### Claim 8 (depends on 1) The transaction card of claim 1, wherein the first dimension and the second dimension comprises at least one from a group comprising a pitch and a length. ### Claim 9 A contactless transaction card, comprising: a body comprising a first outer layer opposite a second outer layer; a corrugated core between the first outer layer and the second outer layer, wherein the corrugated core comprises a plurality of alternating peaks and valleys, wherein two or more peaks of the plurality of alternating peaks and valleys are directly coupled to the first outer layer, and wherein two or more valleys of the plurality of alternating peaks and valleys are directly coupled to the second outer layer, and wherein a first shape of a first set of one or more peaks in a predetermined area of the corrugated core is different from a second shape of a second set of one or more peaks in a remainder of the corrugated core; and an identification chip positioned in a recess of the first outer layer, wherein the identification chip is coupled to the corrugated core in the predetermined area with the first set of one or more peaks with the first shape. ### Claim 10 (depends on 9) The contactless transaction card of claim 9, wherein the first outer layer is made from a first material and the corrugated core is made from a second material. ### Claim 11 (depends on 10) The contactless transaction card of claim 10, wherein the first material is a metal and wherein the second material is a plastic polymer. ### Claim 12 (depends on 9) The contactless transaction card of claim 9, further comprising a magnetic stripe extending along the second outer layer of the body. ### Claim 13 (depends on 9) The contactless transaction card of claim 9, wherein the body defines an outer perimeter including a first end opposite a second end, and a first side opposite a second side, and wherein the corrugated core extends between the first and second ends, and between the first and second sides. ### Claim 14 (depends on 9) The contactless transaction card of claim 9, wherein the first set of one or more peaks of the predetermined area of the corrugated core have a first pitch between two or more peaks of the first set and the second set of one or more peaks of the remainder of the corrugated core have a second pitch between two or more peaks of the second set. ### Claim 15 (depends on 9) The contactless transaction card of claim 9, wherein a width between two adjacent peaks varies across the plurality of alternating peaks of the corrugated core. ### Claim 16 A transaction card, comprising: a body comprising a first outer layer opposite a second outer layer; and a corrugated core between the first outer layer and the second outer layer, wherein the corrugated core comprises a plurality of alternating peaks and valleys directly coupled to the first outer layer and to the second outer layer; and an identification chip positioned in an opening of the first outer layer, wherein the identification chip is directly coupled to the corrugated core, and wherein a first dimension of one or more valleys in a subsection of the corrugated core directly coupled with the identification chip is different from a second dimension of one or more valleys in a remainder of the corrugated core. ### Claim 17 (depends on 16) The transaction card of claim 16, wherein the first outer layer is made from a metal and wherein the corrugated core is made from a plastic polymer. ### Claim 18 (depends on 16) The transaction card of claim 16, further comprising a magnetic stripe extending along the second outer layer of the body. ### Claim 19 (depends on 16) The transaction card of claim 16, wherein the body defines an outer perimeter including a first end opposite a second end, and a first side opposite a second side, and wherein the corrugated core extends between the first and second ends. ### Claim 20 (depends on 16) The transaction card of claim 16, wherein the first dimension and the second dimension comprises at least one from a group comprising a pitch and a length.
