How will I know if my online purchase has this added layer of protection?

This service will automatically work at checkout at any of Visa's participating online merchants. Remember, there’s no need to download anything, install software, or register for an account to get this added layer of protection. When using this service, you may occasionally be prompted at checkout to verify your identity, but this is to ensure you’re you and protect you from fraud.

Lastly, if you see the following Visa Secure badge on participating online merchants’ websites this also indicates the use of this service.
