Because bad sales, some hawkers prefer instant money and couldn't wait for e wallets to cash in because it will take a day or two to transfer to their bank account.

If you see a hawker suddenly stopped accepting e wallets, it means their business isn't doing well.

I tried to be friendly to all of them and they actually let me touch their mpay device for me to verify  the error is "connection refused" nothing they can do but to wait for mpay to come fix their own shit.

My best experience was 99speedmart using their dedicated phone to scan. Yes initially some of the staff don't even know how to use or have access. I talked to the manager suggesting him/her to create cashier profile for them... The next time I go to these branches, every staff know how to use 

I have a feeling that Boost is facing some drama in the team or there's something bad going in there...

The sudden resignation of their CEO is kinda showing something...

Hope I'm wrong, cuz if they fail in the future, the e wallet game here is gonna die off for sure.

Doubt that.
They're under Berjaya ecosystem.

old Town at my place open until 2AM.
Now it's also showing same screen.
Paid with samsung pay.

What phone are you using?

Today tried to pay at KFC Berjaya Times Square, couldn't load the QR code and there was a long queue behind, ended up using paywave, and once the cashier switched the payment method from e wallet to card, then only the QR code came out.

Thanks Digi.

Boost sucks! Failed me when I need it the most. Purposely reload RM1000 and cannot pay for my purchase. I’m going to withdraw all balance and close the account.
