Retail merchants regularly face a challenge in managing consumer's sensitive data related to payment cards and complying with the regulations. The biometrics-as-a-service offerings cater to this challenge, as they help protect consumers’ critical information from unauthorized access. The retail industry is always on the top in terms of cost-cutting, improving revenue growth, profit margins, and adopting the latest technologies. It is one of the most targeted industries by cyber-attackers, owing to the potential payouts and the huge number of monetary transactions made via VISA, MasterCard, and other payment processing networks. This leads to the adoption of comprehensive biometrics-as-a-service offerings in the industry, as data risk is present at all levels, from the various transactions to the confidentiality of personal information of customers and employees. Retailers are also adopting biometrics as- a-service solutions to manage PCI DSS compliance requirement and eliminate data theft risks.
