Vinted is a second-hand fashion e-commerce that allows its users to sell, buy and exchange items that they no longer use in order to give them a second life. Online sales of these products are growing exponentially thanks to the comfort and flexibility offered to users. However, companies are becoming exposed to new risks, including digital fraud and loss of user trust. With the integration of the Number Verification API, Vinted can add an additional layer of security to its authentication processes to reduce the risks to its customers. This tool also simplifies the identification process, making the consumer experience more convenient and straightforward.
