Metal containing transaction cards or smartcards (SC) having a slit (S) formed in a metal layer (ML) or metal card body (MCB) which extends from a perimeter edge of the card body to a transponder chip module (TCM), wherein the path of the slit (S) extends to an area underneath a module antenna (MA) of the TCM. The slit (S) does not reach a module opening (MO) for the transponder chip module (TCM). The slit enters the area of the module antenna (MA) overlapping its windings or tracks and follows the form and path of the module antenna (MA). In some embodiments, the module opening (MO) may be omitted. The shape of the module opening (MO) may be other than rectangular, and it may have at least two parallel sides.
