Great, using Maybank 2 Card Amex to reload Touch 'n go card at Touch 'n go Hub in NU Sentral to gain 6.25 % cashback is better than using grocery cashback credit card in Jaya Grocer to gain 5 % cashback.

Any idea on what the MCC for reloading Touch 'n go card at the counter Touch 'n go Hub is? It is not so important to know the MCC, but I am just curious. 

5x TP - 1.25%

With 5x, it is faster than you thought. I have redeemed a lot of vouchers from AEON and Harvey Norman.
Since 5% cash back was removed (and just recently reinstated), I hardly spend on this card yet I could get 120k of TP now.

So, it is really fast.

Well, Maybank2Cards AmEx comes with cash back and TP is just a bonus.
I didn't specifically spend for TP that time, it is due to that I didn't have a general card for my shopping. That's how I got my TP.

So now, if you have M2Cards AmEx, you get both - cash back (if you spend on weekends) and 5xTP (if it falls under 5xTP categories).
For instance if you reload from Jaya Grocer, you will get 5% cash and 5xTP.

I will need to be very specific with my replies else someone with different level of comprehension may interpret them wrongly.

of course I know that

if using mbb ikhwan Visa petronas with 8% cb, still good deal.

Refer to post #1. The information is there.

Too bad, the machine here is strike by lighting, offline now.

again answer for the n-th time.

as long as the kiosk accept amex, u get cb if swipe on weekends.

real question would be: does it accept amex at all?
