The Problem
Why Sprint Sign Exists
Still printing documents just to get a signature?
You know the drill. Print the agreement. Courier it. Wait for days. Follow up on calls. Get it back with a missing signature on page 7. Start all over again.
Every signature collected the old way costs you time, money, and sometimes even the deal itself.
Sprint Sign ends that cycle. Upload your document, choose who needs to sign, and send it. Done.

4 Ways to sign your customer choose
Not everyone signs the same way. SprintSign supports every major Aadhaar-based eSign method, so your customers can sign the way that's easiest for them.
OTP eSign
Sign with just a mobile number.
The signer receives a one-time password (OTP) on their Aadhaar-linked mobile number. They enter the OTP, and the document is signed — that's it.
- No app, no device, no hassle
- Works from anywhere — home, office, or on the go
- Ideal for remote signing and high-volume workflows
- Best for Customer onboarding, consent forms, agreements signed remotely.
Biometric eSign
Sign with a fingerprint.
The signer places their finger on a biometric scanner, their identity is verified against Aadhaar, and the document is signed instantly.
- Strong identity assurance through fingerprint verification
- Perfect for assisted signing — at branches, service centers, or in the field
- No dependency on the signer's mobile number
- Best for In-person onboarding, field operations, branch-based document execution.
Iris eSign
Sign with an eye scan.
The signer's iris is scanned and matched against Aadhaar records — one of the most accurate forms of identity verification available.
- Highest level of identity assurance
- Useful when fingerprints are worn out or unreadable
- Trusted for high-value and sensitive documents
- Best for High-security workflows, senior citizens, and cases where fingerprint verification isn't reliable.
Face Match eSign
Sign with a face scan.
The signer takes a quick selfie-style face scan, which is matched against their Aadhaar photo. Verified, signed, done.
- No scanner or extra hardware needed — just a smartphone camera
- Fast, contactless, and easy for anyone to use
- Combines convenience with strong identity verification
- Best for Remote signing where extra identity assurance is needed beyond OTP.
Every method is backed by Aadhaar verification — so you always know the right person signed.
