Punched cards may be intended as a visual indicator that a card has been fully used up, and punched holes are mostly observed, as we see here (not on the optical band) on full color Sodeco cards where heat strikes to destroy units on the band are not easily seen. Cards with punches on the band were done so to remove information from the code, most often country info on the left side of the band.

The first demos for the Frankfurt trials of L&G technology are all this type. (Vermillion Sodeco) The early trials, test and service cards are mostly the same deep wine red colour (1980-1982). The second stage of testing (1983-1984), where the Deutsche Bundespost branded cards begin production, the colour of the cards are bright red.
Toward the end of the Frankfurt trials in around 1984, cards with thermal band are produced, but the trial ends with the selection of Siemens Chip cards chosen for the National phonecard telephone network.
