Pandemic shopping: Your best options for NFC and contactless payments
Summary
While delivery services are an option for some of us, there are times when at least one member of the household has to go out to buy critical food and supplies and makes purchases at retailers -- and that requires paying for goods in person. Near-Field Communications, or NFC, is a technology built-in to many modern families of mobile devices, such as the iPhone, the Samsung Galaxy, Google Pixel, and many other Android smartphones. NFC, introduced in 2002, allows contactless data transfer between mobile devices and can to emulate a credit card for payments at POS terminals in retail stores. NFC lets the user pass their smartphone device over a payment terminal at a retailer in order to complete the purchase, provided that a supported "e-Wallet" platform is used. MST (only works on Samsung devices) is useful for terminals that do not support NFC as it is the older magnetic stripe reading technology, but is not as reliable a connection.
