1) Oh, I think that you are referring to Hong Leong Credit Card Terminals, in Jaya Grocer. These credit card terminals have the shape similar to smartphones.

It is nice knowing that Hong Leong Credit Card Terminals in Jaya Grocer can process Amex contactless transactions. 
2) How much was your Touch n' Go reload amount? Below or above RM 250.00?

I am wondering whether Hong Leong Credit Card Terminals in Jaya Grocer can accept Amex contactless transactions above RM 250.00 or not (we tap our Amex credit card and then key in our PIN).

Thank you for your information.

To me it doesnt matter because Amex (im assuming MBB 2 Card) gives cashback regardless Wave or insert card.
U can give it a try and let us know the result whether allow Wave + PIN or not.

No they wont force to charge ur card in a single transaction.
If u insists, u can pay separately RM200 + RM200 the cashier have to entertain u.

FYI i've done that before, topup RM200 make payment using my own Amex, topup RM200 again make payment using my spouse Amex.

Btw who says other card terminals will decline contactless above RM250?

TNGo topup max RM200/transaction. U can opt to pay together with ur groceries or separately.

Actually what difference using wave and not? Got any special campaign running?

Thank you for your information, beebee1314. All the while, I thought that only Maybank credit card terminals can process Amex contactless transactions.
