Mobile payment apps can be a convenient way to send and receive money using your smartphone or smartwatch. Paying for items this way has never been easier, thanks to the availability of numerous mobile payment apps, better payment terminal infrastructure, and wider support for Bluetooth/near-field communication (NFC) contactless credit cards by American issuers. The coronavirus pandemic has also helped to make contactless “everything” more compelling. I tested out five different mobile payment apps: Apple Pay, Google Pay, Samsung Pay, Venmo (by PayPal) and Cash App (by Block, formerly Square) recently, and wrote my review for CNN/Underscored here.
