The magical combination of increasingly connected world, technological innovations and expanding mobile phone market is greatly transforming Fintech industry. India currently is witnessing a transition from a traditional cash driven to cashless economy. Amid this revolution, Finetch firms are embracing technology and leveraging growth of mobile owners to make payments much easier and secure for the end users. Latest ship at the dockyard of technology is “Sound based Payments”. This radical technology is definitely a game changer enabling payments without Internet connectivity. While our devices are ever more connected, but still poor connectivity while using Internet is a big hurdle for making payments. In such a case, data is transferred using peer-to-peer connectivity like Bluetooth, Wi-Fi Direct, or Near-field communication (NFC). But again, these solutions have specific requirements of hardware and APIs which may not be available in all the devices. However, every device comes with a microphone and a speaker. So here comes an alternative, i.e. data transmission using sound waves. Thus, use of sound based transmission in the form of “Sound Based Payment” is going to benefit the Fintech industry the most. Such payments work independently of Internet connectivity or communication tool such as NFC to enable payment. User can offer payment from smartphones, feature phones, card swipe machines and point-of-sale devices with the use of sound.Working of Sound Based Payments Sound based payments can be made by anyone having a bank account and a mobile phone. Using a unique ultra high frequency encrypted sound-based technology will enable you to pay directly from any of your bank accounts or credit/debit cards to the merchant account offline. In the process of Sound wave technology, data is encoded into sound waves with the help of an algorithm which can then be transmitted to make offline payments. To make this happen, algorithm has to be integrated in the buyer’s mobile phone as well as the merchant’s phone or card readers.
- Merchant enter payment detail like bill amount on his device
- Numbers are converted to analog format with using the Algorithm
- Encrypted analoged data is transmitted to buyer’s phone as a sound signal
- Buyer’s phone is placed near merchant’s device to receive signals
- Buyer’s phone receivess data and decrypts the received data.
- Payment can then be made using debit card / credit card / digital wallet.
