Four types of Factory-Cards exist and samples shown under FA1 and FA2 are courtesy from Landis & Gyr. Cards never exit the factory of Zug (Switzerland) and were destroyed when the factory closed in March 2006. The optical geometry of each Factory-Card is perfect and the production costs of such material was high. Factory-Cards of a structure were used to control the quality of Public-Cards with same structure.
----------------------------------------

For each system of countries, 26 sets of cards were produced (from "set #A" to "set #Z") with 5 cards in each set (for example card #A-1 to #A-5 for the "#A set" - cards were mostly numbered per hand).
Such cards always bear the number of the structure (Stu. 1 to 26) in the middle front of the card.
Country code is visible on the left of the optical track.
Settings-Card for countries with Structure 11 (Stu. 11)
---------------------------------------

FA2 - "Monitorings-Cards / Überwachungs-Karten"
For each system of countries, 26 sets of cards were produced (from "set #A" to "set #Z") with 5 cards in each set (for example card #A-1 to #A-5 for the "#A set" - cards were mostly numbered per hand).
Such cards always bear the number of the structure (Stu. 1 to 26) in the middle front of the card.
Front-color of the card is the official color awarded by Landis & Gyr for the card's country/system :
GREEN for England (Stu. 07), YELLOW for Austria (Stu. 08), RED for Switzerland (Stu. 03), etc...
RED-BORDEAUX Monitorings-Card for Taiwan with structure 15 (Stu. 15)
---------------------------------------

Tests of high/low temperatures, oxydation, crash and bits erasing had to be performed and shown to the customer before mass production.
Israëli Commissioning-Card for testing correct erasing of bits on Full-Face-Printing cards
---------------------------------------

FA4 - "Undefined-Cards" (to be developped)
Such cards include all ones which were produced for strict internal trials inside the factory of Zug (Switzerland). Undefined cards have designs and structures which do not match together.
Undefined-Card, without design, without country code and without Control Number
