The credit card reader was instant. You could just put in your laundry, swipe your card, and that was it. Instantly started.
They switched to an app by the same service company, and now there were a bunch more steps involved. Put in your laundry, find the app, open it, scroll through their “what’s new in laundry!” news that nobody cares about, click a bunch of buttons until you find the machine number that matches yours, go through the menus to pick washer settings, then pay there, and still need to push the start button on the machine itself.
So much worse, and also more error prone — I would regularly get errors when a machine disconnected from the internet.
Why people think it’s better, I have no idea. The only thing I can think is that credit card fees are cheaper on a $20 transaction compared to 20 $1 transactions
