# Secure ID Verification

The **Secure ID Verification SDK** allows you to verify your users' legal identities. This is essential to comply with regulatory requirements, such as know-your-customer (KYC). Secure ID verification is required to unlock certain Sudo Platform features, such as [Virtual Cards](/guides/virtual-cards.md). Secure ID verification also offers you peace-of-mind that your application isn't being misused.

Your users will be asked to verify their identity by providing proofs that can be verified against trusted data sources.
