SAMY via JomPay accepts credit card or not first.

I always use JomPay to fund SAMY.
Even though you can select it, I don't think it'll be successfully checked out.

Other banks are making the similar decisions as well, as proposed by Bank Negara.

--- BNM's FAQ ---

Would the Framework cause consumers to be worse-off as banks are likely to cut back on loyalty points, cash rebates and other cardholder rewards?

Cardholder rewards such as loyalty points and cash rebates are funded by merchants through the payment of MDR.  Merchants are likely to recover such cost through higher prices of goods and services. As such, consumers who do not use payment cards may end up subsidising the cardholder rewards enjoyed mostly by premium cardholders. 

With the implementation of the Framework, there is likely to be a dampening in the cardholder rewards. Nevertheless, consumers are not worse-off.  With more affordable payment card acceptance cost, merchants will be less pressured to pass on such cost to consumers through higher prices of goods and services. In addition, more merchants would be able to afford the acceptance of payment cards, in particular the debit card. This would provide consumers with the convenience of using their payment cards widely at more merchant outlets, thus lessening the need to carry cash.

After many years of using mbb cc, the 1st card i recommend is still the maybank 2 cards, amex. Everyone should get it.  Haha.

not possible for now

hlb does not know your mbb card outstanding; both doesnt talk to each other.
another way is you can schedule (future) fund transfer or recurring fund transfer in HLB Connect.

downside is your hlb account must always have money inside before scheduled fund transfer initiate.
