Fast processing no need to wait for approval code.
Quite common at supermarkets, Mr DIY.
But for debit card paywave, it will check if you have enough money in your CASA.

this is online/offline processing, not necessary related to "internet status".
the terminal still can capture the transaction and approve while in offline mode, just not realtime update to bank/card network.
Thanks for the explanation, ClarenceT and cybpsych.
So, as credit card users, we are unable to determine whether contactless transactions are processed online, or offline, right?
From my limited experience of using credit cards, if I tap Maybank credit cards at Maybank terminals (either for Visa Paywave or Amex ExpressPay transactions), the contactless transactions are usually processed online and I can see the approval code on the charge slips.
On the other hand, if I tap Maybank credit cards at Public Bank terminals for Visa Paywave transactions, the approval code becomes VLP111, indicating offline processing.
So, to avoid offline processing, should I need to ensure that it is same bank, both at card issuer side, and card acquirer side? For example, I need to tap Public Bank credit cards at Public Bank terminals, for contactless transactions. Is my understanding correct?
