手机解锁,粘碰收银机就可以了,但收银机设备要更新。支付宝和微信支付也支持NFC,美国99超市就是NFC支付宝和微信支付。而支付宝扫码支付还要再打开爱婆,瞄准码图。当然对设备的要求几乎没有,所以个体户很广泛采用,也便于快速普及。再加上社会主义制度的优越性,迅速高效在中国普及。
apple,google/samsung pay 在很多店, 包括扣私扣,还有一些银行ATM (BA,WF),加油站自主收银(CHEVERON),可以用,但还有很多店还不能用,TARGET,WALMART,CVS(快了),大部分加油站自主收银等。这是资本主义制度腐朽性决定必然导致社会落后,正如马克思一百多年前所预言。资本主义制度下的商家必然追求自己的私利最大化而奋斗,导致社会总体的浪费低效:那些店家都有自己手机支付爱婆,以便锁住自家的客户。美国手机支付还处于战国混战期间,秦王还需要己年才可能统一,但也可能沦为三国疆持,和和。
中国现在是利用社会主义制度的优越性推动商品经济的发展,对美欧等发达国家的原创科技迅速高效地采用,进而实现弯道超越西方国家。而可怜的西方国家受其(民主)资本主义制度的枷锁限制,原发科学技术无法在本国高效采用,却首先贡献给了中国采用。下一个超越可能是5G网,私家电动汽车。很明显,美国人已经意识到了危机:
Ed Baig gives a look at the new Apple Watch Series 4. One key new feature: fall detection.
Corrections & Clarifications: A previous version of this article incorrectly stated who gets a percentage of transactions made through Apple Pay.
Apple Pay continues to gain traction in the mobile payments competition, most recently adding Costco to the retailers letting U.S. customers pay with the tech giant's smartphone app.
A notable holdout: Walmart, the nation's largest retailer.
Costco, the No. 4 retailer in the U.S. according to the National Retail Federation, recently began accepting Apple Pay at the warehouse club giant's 520-odd stores in the U.S. Overall, Costco has 750 stores in the U.S., Canada and around the globe.
The company said it is also working to make mobile payments available at its gas stations, too.
Costco is the latest major partner Apple Pay has gained. Recently, CVS and 7-Elevenbegan accepting the mobile app.
"Apple, it seems, has been really deliberate in the past couple partnerships it has announced (in that) all those retailers share the commonality of having shoppers that go there on a regular basis and those types of stores consistently," said Rahul Chadha, an analyst with research firm eMarketer.
About 22 million people use Apple Pay in the U.S., eMarketer says, with growth of 9 percent expected to push that to 24 million next year.
Apple says there were “well over” 1 billion Apple Pay transactions completed during the three-month period that ended June 31 – three times the number during the same period a year ago.

There's one condition of using Apple Pay at Costco: If you use a credit card, it must be a Visa because of an in-store exclusive deal the retailer has with Citigroup and Visa, according to PaymentsSource, a news site that covers the payments industry.
That same condition applies should Costco customers want to use other mobile payment options Samsung Pay and Google Pay, the site says.
With other retailers now accepting Apple Pay, might Walmart follow suit? Don't hold your breath.
"While we recognize that there are mobile payment options, such as Apple Pay, Walmart Pay is currently the exclusive form of mobile payment accepted at Walmart," Walmart said in a statement.
Walmart long has been a holdout, in part because the retailer collaborated with CVS, 7-Eleven and other retailers such as Target and Best Buy in developing a competing mobile payments system called CurrentC that never officially launched. JPMorgan Chase acquired the technology last year for its Chase Pay platform.
When that collaboration failed, Walmart launched its own mobile payment app. The retailer began testing its Walmart Pay mobile app in December 2015 at select stores around Bentonville, Arkansas, where the company is headquartered. Since July 2016, customers at all Walmart stores have been able to use the app.
To use Walmart Pay, customers open their app in the checkout line, and the clerk scans a QR code to complete the transaction. (With Apple Pay and other contactless payment systems, customers hold their smartphone next to a payment reader.) The transaction is billed to the customer's payment card associated with the app, and a receipt is emailed to the customer.
After Costco's move, Walmart told MacRumors, the Apple news site that first reported the development: "Walmart Pay is the exclusive form of mobile payment accepted at Walmart, and we have no plans for that to change."
Along with Starbucks, Walmart has become successful with its own mobile payment platform because it incorporates a reward program in the app. "That makes the checkout (process) clear for shoppers," Chadha said.
Costco customers must still show their membership card when they checkout, Chadna says.
Another reason Walmart wouldn't quickly move to join the Apple Pay bandwagon, Chadna says, is the cut the banks get from transactions – about 0.15 percent.
"When you are talking about the types of volumes Walmart does, why would you want to hand over even that slice of the transaction amount?" he says. "Just keep it all in-house."
