  • Quick, easy, convenient purchases
  • No cards, no checks, no wallet, just your smart phone
Use your smart phone to pay in stores without swiping your Mainstreet credit and debit cards. It’s private and secure! A unique Device Account Number is assigned, encrypted and securely stored. So, your actual credit or debit card numbers are not shared with merchants or transmitted with payment. For added security on some smart phones, enable the fingerprint/Touch ID security feature.
