Across the world, disruptive technologies from companies termed fintech, are providing financial services in a more tech-savvy way and in lightning speed, making potential customers slowly drifting away from the traditional services offered by banks. Having said that, banks have started realizing the power of Big Data, Data Analytics, Artificial Intelligence and lastly Blockchain. Big banks in India are now deploying big data to customer profiling, collaborating with e-wallets to make the payment system more convenient, putting analytics into play in creating loan scorecards and gradually partnering with fintechs to leverage their technology for superior customer experience. Bangladesh, albeit trailing far behind from India when innovation in banking service is in question, it started making strides. Top-tier banks coming up with smart downloadable mobile apps, emergence of the first-ever blockchain-backed universal payment platform namely uPay, the first e-wallet namely iPay are all testimonials that Bangladesh’s financial sector is on the cusp of technological disruption. Having said that, wealth of unstructured data, information availability and dearth of tech experts pose big challenge in this realm. Its time banks should realize the importance of data and start putting technologies into play.
