Add WSB Debit MasterCard to your Digital Wallet! 

Smart phone users can now shop with the convenience and security of digital wallet, instead of their cards.  Digital wallets transmit payments securely.  You don’t have to show your card or card number.  To pay, just hold your smart phone near the contactless reader.  The phone will let you know your payment was successfully. Tap and pay is that fast, that easy! 

To get started add your WSB Debit MasterCard to your phone’s digital wallet app.  iPhone users use the Apple Pay system by tapping the “Passbook” or “Wallet” icon on your iPhone 6 or 7, iPad Air 2, or iPad mini 3.  Then follow the instructions to “add a card”.  The Samsung Pay and Android Pay versions will be ready for the WSB MasterCard on October 4th

Once your card or cards are uploaded and verified they become part of your "digital wallet" that will allow you to pay for your purchases with just one touch.  Use it at any of the rapidly growing list of merchants where digital wallet, near-field transactions are accepted. And coming October 4th: Samsung Pay and Android Pay!  Stop fumbling with cards.  Start using your digital wallet!  Upload your WSB Debit MasterCard today!
