Indala26 format

The flipper magically converts the HEX code into facility ID and card number. The problem is when I use online calculators the numbers don’t match. Does anybody know of a calculator that works - or failing that does anybody know the Indala format?

I wonder there is no answer yet… I am also intrested in.

Maybe starting by getting a bunch of Indala cards, check the number, read with flipper, check the keys that flipper show and try to make a connection to the numbers written on the card ???
There is also a chance that the numbers on the card are not related with the numbers that the card ID with to the reader (like a key code that might be a direct bitting code to cut the key or an indirect one where you check on a table or software the direct bitting cuts/measures from the indirect number written on the key).
