Bangalore-based Canara Bank Monday deployed its first biometric ATM in one of its Mumbai branches, according to a local report. The branch is in Dharavi, considered Asia's largest slum neighborhood, according to the report. A large number of poor bank customers will use the biometric ATM, the report says. "Biometric ATMs are designed mainly for the rural population who are characterized as illiterate and have little access to financial services," says Prathima Rajan, an India-based analyst with Celent LLC. Rajan says banks use biometric ATMs to secure the business of farmers and artisans in India. "Biometric ATMs are gaining popularity lately as they include this large untapped population in the banking-user community," Rajan says. She adds many large banks that market to rural consumers expect to deploy biometric ATMs. Canara Bank did not respond to CardLine Global requests for comment.
