It is a nice app. It reduces the pain of NEFT and IMPS. It is a very user friendly app and works like shareit, through which people can transfer various phone docs like images, videos etc to another nearbu device. In the same way through Tez App one can transfer its bank account money from its linket bank to anyother person’s bank with the nearby connectivity. Its the same concept but different asset.
Here Money can be transfered with just one click.
But at the same time this app is way too risky. In case your phone is lost or stolen and you have this app logined yur bank account it will take fraction of second for the theif to transfer your money into some of his account. And once its tansfered and widrwan you can do nothing about it.
Therefore once you attach your bank account its important to not keep your google pin predictable. Otherwise you can face a major issue.
