I'm currently using NETSPay [1] in Singapore to do e-transactions.

It's a bit cumbersome at the moment; most shops assume I'm using NFC to pay (which I think is the default option) but my cheap Xiaomi android phone doesn't have NFC, so I have to ask them to print out or display the QR code for me to scan using the app.

Other than that, it works: once scanned, the transaction completes within seconds.

You should explicitly say that you wish to pay by "NETS QR". Otherwise they assume you mean by card or NFC.
