Hyatt Gold Passport - What is the number to the right of MASTERCARD on the receipts?

Hi -

Does anyone know what the number means on the receipt that gets slipped under your door that is below the room charges and the the right of the name of the charge card used? Its in the section of the receipt where each charge is listed out.

Something like:

Total Due xxx.yy

MASTERCARD 6704218009678

Thanks.

I don't know, but I've always wondered the same thing.

Don't know either - maybe we can giveaway a toaster to the one that does - oops better not :D

Well - I thing I noticed is it does not show up on pre-paid rates where the first line item in the billing activity says PREPAYMENT.

It does show up when its not a pre-paid rate.
