The Samba eSecure is available for free on iOS and other smartphones. It allows you to protect your credit card from online criminals when shopping online, by sending you a passcode so your bank will recognize you as the person initiating an online transaction. How it works: Download the Samba eSecure Application, and when you are shopping online, you can request a passcode to enter at a merchant’s website during checkout, to verify that you are the registered cardholder, to prevent fraudsters from stealing and using your credit card information.
You can enter multiple credit cards and multiple users into the app, to protect online transactions for your whole family.
