Business Debit Cards

One card organizes your business life. 

Business members with a checking account may request a free Mastercard® debit card. You can use it to make purchases anywhere Mastercard is accepted and withdraw cash at nearly 30,000 surcharge-free ATMs nationwide. 

Our debit cards are protected with EMV chip technology and also have a magnetic stripe so you can shop with merchants that do not have chip-enabled payment terminals.

  • Use your debit card with the CardNavSM card control app for additional protection against fraud.  
  • Apple Pay®, Google Pay™, and Samsung Pay® are available for SLFCU debit cards. Learn more about contactless payments with mobile wallets.

Activate your debit card: Call the number provided with your card or 800.947.5328.
Report a lost or stolen debit card: Call 800.947.5328.  

If you receive a call regarding a blocked transaction on your debit card, please call 888.241.2440.

Using Your Debit Card When You Travel

Using Your Card When You Travel

Notify SLFCU of travel plans to keep your cards safe and working.

Your SLFCU credit card and debit card are protected by a system that detects unusual patterns of activity. Please let us know when you are planning a trip, especially one that takes you outside the U.S.

When activity is detected outside of your normal pattern, you’ll receive a phone call to verify the purchase is legitimate. Please provide us with your cell phone number so we can reach you when you’re away from home. 

Card fraud is a widespread problem that you can help prevent. Call us at 505.293.0500 or 800.947.5328 or send a secure message in online banking, and we will make sure your cards are safe and continue working when you leave home.

Please provide the following information:

  • Complete credit card or debit card numbers
  • Countries to which you will be traveling
  • The dates on which you will begin and end travel

Using your Visa or Mastercard® credit card to make purchases overseas is a smart move. You'll be charged only the official exchange rate, plus a 1% international transaction fee.

Use your debit card worldwide anywhere Mastercard is accepted to pay for your purchase or get local currency from your checking account.

Please note that some foreign ATMs may not allow access to savings accounts. If you will be traveling outside the U.S., SLFCU recommends that you have a debit card attached to a checking account or use a credit card for purchases/transactions.
