5 digit & 9 digit cards

[asemerdjian@xxxxxxxxx]

We have numerous locations, all of which are using 5 digit prox cards.
Our office is setup to use 9 digit prox cards, setup to use Wiegand.

Our Card formats use "S 1 D 1 B1 B2 B3 B4"
but when we use the other office cards (5 digit) the numbers do not
match the card?
I would only suspect that if we tried to use us in their office, we
wouldnt match either.

Could we mix our formats to read both 5 & 9 digit card formats
correctly?

We use Win-Pak Pro 2005.
How would I also know what x-bit cards these are?
