The invention concerns a method and a system for production of RFID smart labels or smart label inlays, in which a multiplicity or RFID straps (11) are connected in succession with a multiplicity of antennae (20), where in a first step the RFID straps (11) to be arranged on a strap substrate band (5a) are separated (8, 9) and mounted on a substrate band (1, 1a, 1b, 1c; 10, 10a-c) for the smart labels or smart label inlays to be produced, and in a subsequent second step the antennae (20) are mounted on the substrate band (1, 1a, 1b, 1c; 10, 10a-c) and on first connection surfaces (26) of the RFID straps (11) such that the connection surfaces (26) of each RFID strap (11) electrically contact second connection surfaces of the antennae (20) allocated to the RFID strap (11) or the first connection surfaces (26) are positioned for electrical contact and fixed on the second connection surfaces.
