As we understand that merchants are looking for a sound box to announce their payments even if they are using a different UPI provider apart from PayTm. AS currently in the market only PayTm offers sound box. So our Research team is carrying out various experiments and after spending good amount of research we at the moment support successfully the below listed UPI Merchant wallets :-
Talk It All Payment Soundbox is a Fintech IOT device to be used by Shop Owners, Merchants, Restaurants, Small vendors etc for instant payment sound & visual confirmation. It can work with any UPI providers like PayTm, Google Pay, PhonePe, Freecharge etc.
Once you buy a Talk It All sound box from your Bank or UPI Provider, getting started is easy.
Note :- Assuming the device is shipped to the merchant pre configured by the UPI Provider.
