Two Factor Authentication Certification India

Hi

We have developed a 2 factor authentication solution and i was wondering if there are any specefic certifications that the product must meet to be saleable to banks.

I am aware of OPSEC for implementing it as a VPN solution , but for pure authentication purposes are there any specefic certifications i should look at .

I am particularly interested in certifications that may be offered by India authorities to be acceptable by India banks

Thanks
