We often refer to Mills42 as the small but mighty credit union. Let us introduce you to our poster child for that expression: The Mills42 Mastercard® Debit Card.

You can use it 24/7 for both online and in-store purchases wherever Mastercard® is accepted. Even better, you can use it with Apple Pay™ and Samsung Pay™. Plus, through our participation in the CO-OP Network, you can use it at over 50,000 fee-free ATMs nationwide to withdraw cash, make deposits, check your balance, and in some cases, even deposit checks into your Mills42 checking account.

Link your Mills42 checking account to our Round Up Savings Account, so every time you use your Mastercard® Debit Card, we’ll transfer the difference between the purchase amount and the next whole dollar amount right into this savings account. You’ll be painlessly saving money, while earning interest on that money at the same time.

Impressed? We think you will be. Apply online, give us a call, or come in and open your Mills42 Checking Account today so we can hook you up with a Mastercard® Debit Card of your very own. And, don’t forget to ask about Round Up Savings, too.

Not a member yet? We’ll take care of that for you as you’re opening your account or taking out a loan. If you want to get a jump-start, enroll online or just give us a call at 978.328.5100. We’ll be happy to help you build from here.
