More than 87 percent of smartphone users ages 14 and older in China will tap, scan, or swipe those devices to pay at a point-of-sale this year, according to a new survey by Insider Intelligence.com. Yet only half as many U.S. smartphone users in that age group, about 43 percent, will use proximity mobile payments, as mobile wallets are still catching on in the U.S.

Insider Intellingence.com describes a proximity mobile payment as “a point-of-sale (POS) transaction made by using a mobile phone as a payment method.” (Proximity mobile payments are also known as POS mobile wallet payments and POS mobile contactless payments.) Examples include Google Pay, Samsung Pay, and Apple Pay.

Methods used for POS transactions include scanning, tapping, or swiping a mobile phone at the POS to complete a transaction. Purchases of digital goods on mobile phones, purchases made remotely on mobile phones that are delivered later on, and transactions made via tablets are not counted as POS transactions.
