Fraud Prevention
The best defense against fraud is knowledge and understanding how to prevent it.
- Protect your account information; do not carry your PIN or bank account information in your wallet.
- Never sign blank forms or documents.
- Never wire money or send funds to anyone you do not know and trust.
- Do not share personal information over the phone, online, or on social media.
- Use strong passwords with more than 8 characters in length; include capital letters, numbers, and special characters (!@#$*).
- Change your password frequently, and do not use the same password for multiple websites or accounts.
- Use secure internet connections that are set up with a password; fraudsters can access information through free Wi-Fi connections.
- Use antivirus protection and make sure the software is up to date.
Contact us if you have any questions about fraud, or if you think you may be a victim of fraud.
