Visa 3D Secure
Visa 3D Secure makes the most secure online shopping experience possible by helping prevent the unauthorized use of a cardholder’s card number — in turn, reducing fraud and reducing danger of identity theft.
With Visa 3D Secure, there is no need to register your card since 3D Secure uses dynamic authentication when a Visa card is used at participating online merchants.
Card use that is outside of your normal area or overseas can raise a flag with the fraud prevention team. This may cause your card to be temporarily blocked until we can verify a valid purchase.
Set travel notifications in the Cards section of the SunMobile app or SunNet Online Banking. You may also submit travel notifications in your nearest Suncoast branch or by phone at 800.999.5887. Travel notifications should be set at least 3 days prior to going out of town to avoid the inconvenience of a blocked card while traveling.
Disputing Transactions on Your Account
If you believe there’s been fraudulent activity on your account or if you’re unable to resolve a dispute with a merchant about a transaction, Suncoast can help.
Log in to SunNet Online Banking to dispute a transaction. Simply click on the envelope icon next to the transaction you’re disputing, then click “dispute” and follow the prompts.
You may also file a transaction dispute by signing in through the SunMobile app on your device and browsing to the Account History screen. Be sure to use the most updated version of the app that was released on November 22, 2016.
You may also dispute a transaction in person at a Suncoast Service Center or by calling the Members Contact Center at 800-999-5887 — Monday through Friday 7:00 a.m. to 8:00 p.m. and Saturday 8:00 a.m. to 1:00 p.m.
