Credit card payment

1. Even though you have dropped cheque on the due day, only if the bank realizes the amount with in the same day, if not bank can levy late payment charges.
2. If the cheque and credit card are from same bank (Standard Bank) they can consider one day delay in the payment, as you are not a defaulter.

3. If the cheque and credit card are from different banks, it would take 2-3 days for the bank to realize the due amount. even if they levy late payment charges, you can approach through customer care and ask them for removal of interest charges.

I think Mr. Girish Kumar has given some valuable suggestions.

The payment due date in respect of Credit card is considered as the date by which the Bank should "receive" the payment and not the date by which you 'make" the payment. These days since the accounts are automated, the late charge will be automatically included in your next Bill after say 23:59 Hrs on that date. Sometimes, if the delay is one day or so, then on your request and if your credit rating is good, the Bank may waive off the Late fee by crediting the amount in your Credit Card account.

The Bank should receive the payment by due date. You shall be liable to pay late charges. 

All the above comment give you so many valuable suggestion.
