Pros
In tonetag technology allows users to make payments or transfer money by encoding transaction data into sound waves, which can then be transmitted between devices equipped with speakers and microphones. This method of communication enables payments without the need for NFC (Near Field Communication) or internet connectivity, making it particularly useful in regions where these technologies are not widely available. ToneTag's solutions have applications beyond payments as well, including retail, banking, transportation, and more. They aim to provide convenient and secure digital payment solutions that are accessible to a wide range of users, including those with basic mobile phones.
Cons
Nothing negative from my side it good for employee.s
