Greenwald Pay App No coins. No Cards. No problem. Use our mobile app to pay for your laundry. The Greenwald Pay app makes laundry easier. Just add funds to your account*, select your machine and start your laundry. Through the app you can view your account history, check for available machines and get status updates on your laundry’s progress. No need to wait around. * Please note that your Greenwald Pay app account is separate from any laundry card accounts. Balances from a laundry card cannot be transferred to your Greenwald Pay account and vice versa. If you haven’t used the Greenwald Pay app before you will need to create an account on the app. **The app will rely on your phone having a wi-fi, 3G or 4G signal inside the laundry room to activate the machines - and also to see the countdown on the cycle if you leave to do something else while your wash completes. As long as you're connected, you can see how long is left on your chosen cycle and get on with other things instead of waiting in the laundry room. By downloading this app, you agree to the following Terms and Conditions: You accept that you have a non-exclusive license to use the app. You agree not to copy the app or infringe our intellectual property rights in the app. The minimum amount of top-up credit you can buy is $5.00.
