MUMBAI: A RBI working group on Wednesday recommended technical standards for use of finger prints by banks to ensure security of operations as financial institutions spread their services to remote areas.
The working group on standards for raw images of fingerprints suggested that banks should take prints of two fingers of a customer.
The final decision on the number of fingers and prints, it added, should be left to the banks which may take a view depending on the business requirements.
Recommending the common technical norms for finger printing, the working group said, finger image data should be stored, recorded and transmitted in uncompressed bit packed form.
It further suggested that the banks should use at least 200 gray levels to capture the image of the fingers. The RBI had set up the group to evolve common and comparable standards for enabling IT-based solutions for banking services.
The group also looked into major initiatives taken by banks like State Bank of India and ICICI Bank for introducing IT-based solutions for financial inclusion.
