- The use of data to improve the customer experience
Banks are increasingly obliged to call on Big Data technologies to get to know their customers better and create closer, privileged links with them. By familiarising itself with each customer, the bank can, as a result, personalise its services and respond adequately to their needs.
- A new tool against bank fraud
Whether the attempt was successful or not, most of us have been the target of bank fraud: theft of a bank card, a fraudulent online purchase, or a phishing email. Machine-learning algorithms allow unusual transactions to be detected. In order to do this, banks can cross-reference a request for authorisation of a payment by card or transfer with the transaction history of the same client, which permits the risk level of the transaction to be evaluated.
A genuine decision-making tool, Big Data must be seen as a helpful instrument that will become ever more present in everyday life. And this is just the beginning.
