SIDA1 Venezuela 1984 (Ex Alex Rendon) 9000 Lire loading pattern

The first card system tested in Venezuela in 1984, was the SIDA system used in Italy in the 1970-80's. The only card documented from Venezuela was the general plastic SIDA card. This same card was also used to test the parliament cards in Italy for the Camera dei Deputati.
These cards are distinguished by a hole punch in the far corner. (Cards for other use had the hole punch in a different position)
Alex Rendon obtained this one example direct from someone in CANTV, but they look identical to the Deputati test cards for the Parliament of Italy system, (including hole punch position) with one major difference to the Camera Dei Deputati test cards of 1984: The configuration of the magnetic ARC pattern.

The coding for SIDA1 Venezuela, is in the same format as the Type 2 Italian phonecard ARC magnetic coding, and the cards were intended as BS.100 or 800 units. The coding position is the same used for the L9000 card of Italy, with 4 bar positions as shown here.

Here is the coding pattern on the SIDA1 Venezuela

We can compare this with the Camera Dei Deputati codification, where the pattern is different, but configured as a phonecard with different units probably:

Now we can compare with other usage, SIDA sun-tanning facility, and Credit card demos:
