Needham Bank recommends that you shop with merchants you know and trust. Making sure any internet purchase or shopping cart is secured with encryption to protect your account information. Look for secure transaction symbols such as a lock symbol in the lower right-hand corner of your web browser, or “https://…” in the address bar of the website. Once you've completed your purchase, log off from any website after a purchase transaction is made with your credit or debit card. If you cannot log off, shut down your browser to prevent unauthorized access to your account information. If you want the most secure option, Needham Bank offers MasterCard® SecureCode Internet Personal Identification Numbers on all NB Debit MasterCard®.
