To complete an authorization process with our bank we need just a general information from you: 1) the name of your credit card company (Bank name) BECAUSE different banks need a different instruction how to make the transfer 2) the amount of your credit line (the maximum you can get from company to one card) BECAUSE I need to calculate the amount for our weekly budget 3) the amount of your unpaid balance (the minimum you can get to one card) BECAUSE I need to calculate the amount for our 1st transaction
