Fragmented Processes Create Risk
Icon

Description
Traditional onboarding often relies on emails, spreadsheets, and manual approvals — increasing operational delays and limiting visibility into identity risk.

Manual Verification Slows Growth

Collecting and validating ID and address proofs by hand consumes valuable time, reduces efficiency, and introduces the possibility of human error.
Title
Sensitive Data Needs Stronger Control

Step 1: Contact Verification
Description

Start by confirming that the person or vendor you're onboarding can be reached:

  • Validate mobile number with OTP using Mobile Number Verification API.
  • Confirm email ownership with a one-time link or code using Email ID verification API.

Title
Step 2: Identity Verification Using Officially Valid Documents
Description

Next, verify identity using one or more Officially Valid Documents:

  • The user uploads images of Passport, Driving Licence, or Voter ID (as applicable)
  • OCR APIs read the document and extract key data points – name, date of birth, document number, expiry, etc.
  • Verification APIs such as Passport Verification, Driving License Verification and Voter ID Verification API check this data against the relevant issuing authority or registry (Passport authority, RTO/MoRTH, Election Commission, etc.).
  • Face match compares a live selfie with the photo on the document to prevent impersonation.

Step 3: PAN & Financial Identity Checks (If Required)
Description

For roles or vendors where financial risk is higher:

  • Online PAN verification API confirms the PAN against the income-tax databases.
  • Name match API ensures the PAN holder's identity aligns with the person or entity being onboarded.

Step 4: Video KYC & Liveness for High-Assurance Journeys
Description

Where regulations or internal policies require an additional layer of assurance:

  • Video KYC Services enables remote in-person verification.
  • Liveness check Services ensure the person on camera is real and present, not a recording or a spoof.

Step 5: Address Verification & Standardisation
Description

To support HR, background checks, and vendor due diligence:

  • Address match API validates the address fields captured from documents or forms.
  • Geo APIs can help verify location details and normalise addresses into a standard structure for downstream systems.

This ensures clean, reliable address data for payroll, logistics, and compliance workflows.

FAQ's
Question
Is Aadhaar mandatory for this onboarding journey?
Answer
No. The flow is designed around Officially Valid Documents such as Passport, Driving Licence, Voter ID, and PAN. Aadhaar-based eKYC can be added as a separate journey where permitted and appropriate, but it is not a dependency for this use case.
Question
Which documents can be used to verify employees and vendors?
Answer
You can configure which OVDs to accept based on your policy, typically Passport, Driving Licence, Voter ID, and PAN. The platform uses OCR and verification APIs to read and validate these documents against trusted sources.
Question
Can the same journey be used for both employees and external parties, like vendors or gig workers?
Answer
Yes. The same verification stack can be reused for full-time employees, contractors, gig workers, vendors, and partners. You can define different flows or rule sets per segment (for example, extra checks for high-risk roles or critical vendors).
Question
How does this integrate with our existing HRMS, ERP, or vendor management system?
Answer
All checks – OVD verification, face match, PAN, risk screening, and digital signing – are exposed via APIs. Your HRMS, ERP, or VMS can trigger these APIs, receive responses, and store outcomes, allowing onboarding to stay inside your current systems while the verification happens behind the scenes.
Question
How is data security and regulatory alignment handled?
Answer
Data is transmitted over secure channels and stored according to your agreed policies, with access restricted to authorised teams and systems. The verification flows are designed to support organisations in meeting applicable KYC, data protection, and internal governance requirements, without making exaggerated guarantees about performance or security.
