Traveling soon? If you plan on using your HFCU Visa or MasterMoney Debit Card while traveling, particularly outside the northeast, please notify a Member Service Representative in advance. Card usage that differs from your historical usage pattern will likely prompt Fraud Prevention Services (FPS) to flag your account and contact you to verify the transaction. You will be asked for the LAST 4 DIGITS of your social security number for verification. Never disclose your card number, PIN, or entire SSN. If FPS is unable to contact you, the card may be blocked. Advising Hartford Federal of your travel plans in advance will avoid the inconvenience of a blocked card.
