Abstract
A transaction card for dual interface communication of a transaction includes a card body, a chip opening, a discontinuity, and a transponder chip. The card body includes a first metal layer having an outer peripheral edge, a first metal face, and a second metal face. The chip opening includes a first chip hole transversely extending from the first metal face toward the second metal face thereby defining a first metal edge surrounding a predetermined hole shape. The discontinuity extends from the outer peripheral edge to the first metal edge. The transponder chip module has a module antenna and is configured to be received within the chip opening. The module antenna defines an outer antenna edge surrounding a predetermined antenna shape such that the predetermined antenna shape is the same as the predetermined hole shape for improved inductive coupling via the discontinuity during use.
