Trusted across identity, age verification, and digital signing

ID verification your customers will actually complete

Most identity checks ask customers to upload documents, take selfies, or complete long forms. That creates friction, slows onboarding, and gives genuine customers more reasons to abandon the journey.

OneID® verifies identity through the bank app or online banking service your customer already uses. It's fast, consent-led, and 100% digital, helping you confirm who you are dealing with without making verification feel like a barrier.

Choose the right level of identity verification

OneID has developed a range of identity verification products that provide real-time information about your customers, depending on the level of assurance and data your business needs.

ID Live

Verify a customer is present and in control

ID Live confirms the customer is interacting with the journey by asking them to authenticate through their bank.

Use ID Live when you need a real-time, consent-led customer authentication step.

ID Check

Check customer identity with bank-verified data

ID Check confirms key identity information such as the customer's full name using data verified by their bank.

Use ID Check when you need a fast, low-friction way to check that a customer is genuine.

ID Proof

Prove identity with additional customer data

ID Proof can confirm subject identifier, full name, contact details and date of birth, helping your business build a stronger view of customer identity.

Use ID Proof when your onboarding journey requires more complete identity information.

ID Assure

Add fraud checks and stronger identity assurance

ID Assure includes identity data plus additional checks against activity history and identity fraud attributes. This helps provide evidence that your customer has not previously been associated with fraud, or that their identity has not been compromised.

Use ID Assure for higher-assurance onboarding, fraud prevention and regulated customer journeys.

How it works

OneID facilitates the capture of the required customer details and authenticates the customer in real time.

01

Customer gives consent

The customer agrees to share their personal information with OneID and is directed to their bank.

02

Customer logs into their bank

The customer authenticates using their online banking service or mobile banking app.

03

Bank confirms identity

The customer's bank confirms their identity and sends the relevant identity details through OneID with the customer's consent.

04

Your business receives verified data

Your system receives the identity information needed for onboarding, compliance or customer decisioning.

Only the data subject can agree to the data share, because they are the only person who can log in to their bank account. Bank data, including identity details, is secured by the bank using some of the strongest security available.
