Last time, a lot of retail don't want to accept AMEX because of the higher merchant fees compared to VISA and Master.
But since Maybank bought over the franchise, a lot of major retail outlets are already getting the merchant terminal for AMEX.
In M'sia, AMEX under Maybank arms had turned into Credit Card (correct me if I'm wrong, limited knowledge on AMEX also). But if one holds the true AMEX, it's supposed to be a charge card; same as DINERS.

I try to explain from my understanding:
MBB Amex (Maybankard Amex) has MBB logo. You will earn TreatPoints. All are Credit Card. E.g.
Maybankard American Express Gold & Classic
Maybank Islamic Ikhwan American Express Platinum and Gold & Classic
Amex's Amex (American Express) does NOT have MBB logo. You will earn Membership Reward points. There are Charge Card and Credit Card.
e.g. of Credit Card
American Express® Gold Credit Card
American Express Platinum Credit Card
Singapore Airlines KrisFlyer American Express® Gold Credit Card

e.g. of Charge Card
The Platinum Card®
American Express Gold Card
American Express Personal Card
and also the Centurion card.
Summary:
MBB Amex has Credit Card only.
Amex's Amex has both Charge and Credit card.

Not true..

MBB Amex is still considered charge card, and it does not belongs to the Visa/Mastercard that is so-called as "credit card".
MBB Amex cant be used on machines that does not have Amex acceptance

My understanding is charge card needs to settle full payment every month. Credit card can opt for minimum payment.

Not really, u can opt not to pay but the interest rate can kill u..

Although MBB Amex is slightly different with the conventional American Express card, but its still belongs to that category..

The correct terminology/classification (Issuer) is broken up as:-
1. Visa/Mastercard
2. Visa/Mastercard Electron
3. American Express/Diners cars
4. JCB/Maestro (Japan/Europe)

Then, why does MBB Amex earns TP and Amex's Amex earns MR ?

Why MBB Amex not earn MR ?

The term "credit card" or "charge card" is not by the merchant company.
Credit Card is known as it is because of the power to revolve while one is still with credit balances.
Charge card however is known as charge card because in the even that your didn't pay the last outstanding amount, you wouldn't be able to use it.

@cute_boboi,
Er.. because MBB Amex belongs to MBB whilst Amex Amex that uses MR is really via Amex.

Becoz for Malaysia, MBB Amex is just part of a "brand", cardholder are actually dealing with Maybank directly for everything including transcation and payment and American Express is just a back-end guy that receive some interest/benefit from Maybank.
If u have a American Express card, u are dealing directly with American Express and Maybank wont get a cent.

Get wat i mean?

@cute_boboi,
Ah well.. whichever Amex U go for, it's all issued by MBB here.  tgeoklin oredi mentioned MBB bought over the Amex franchise for MY.

OMG! This thread has lost its guts since 2 days back. It suddenly sounds gangsterism and very “Ah Beng” type.  
Before this I was quite interested in this cc, as it gives 1% cash back without a max cash rebate limit per month. However, after enquiring with HLB CS just now, it is not as straightforward as what I thought. I have changed my mind now.

1. Cash rebate is fixed at 1% and given to all retail transactions (excluding petrol), subject to a minimum purchase of RM100.
2. Cash rebate amount per transaction is rounded up. For example, if you spend RM100, the rebate is RM1. However, if you spend more than RM100 but below RM200, the rebate is still RM1. Let’s say your spending is RM199, you will still get a rebate of RM1, and not RM1.99.
3. AF – 1st year FOC. From 2nd year onwards, you ought to spend at least twice a month or RM8k per year, in order to get it waived.
4. No reward points are given

All these stringent T&Cs, especially item 2, drive me away!
