1. A RFID transponder, comprising:
a textile carrier substrate with a flat thread structure formed as a knitted fabric;
at least one electrically conductive antenna thread which is introduced into the flat thread structure of the textile carrier substrate;
an RFID chip module with a chip-bound module antenna, which is applied to a first side of the textile carrier substrate so that the module antenna is coupled inductively into a transponder antenna formed by the at least one electrically conductive antenna thread,
at least one hot-melt adhesive yarn is introduced into the flat thread structure of the textile carrier substrate,
wherein the hot-melt adhesive yarn includes a spinnable fibre with a coarse fineness range between 10 decitex (dtex) and 200 decitex (dtex) and a melting range between 80° C. to 140° C., and
wherein the flat thread structure has a plurality of second hot-melt adhesive yarns without a carrier yarn, which are knitted into the flat thread structure as long weft threads, as partial weft threads, or as a combination of long weft threads and partial weft threads.
