Germany L&G Debit Karte
40 unit 1.5mm band
NO serial number but loaded
From just a small handful of cards needed for these internal trials, an even smaller amount were not required to be serial numbered, or perhaps removed prior to numbering. Extremely rare.
Toward the end of the Frankfurt trials some preparation was begun for further trials. Cards with thermal band were investigated, with a 92 unit trial printed as a specimen. This was followed by some internal trials of Kredit and Debit (40 unit and 80 unit) cards, but the Frankfurt trial ends with the selection of Siemens Chip cards chosen for the National phonecard telephone network.
