The starting point is laminar bodies, which are coincident in terms of shape and size with the cards to be obtained, of appropriate stiffness, to which is fastened, removably, a continuous strip of paper to allow, likewise, continuous printing thereof "at the expense of" the data supplied by a computer to the corresponding printer, which printing is embodied in the form of a bar code for each one of said cards, which code can subsequently be analysed with the aid of a bar-code reader, each one of said cards finally being plasticized in order to prevent manipulation of (tampering with) the aforesaid bar code. <IMAGE>
