Apple Pay, Facebook Messenger Pay, Android Pay, Google Wallet…to name a few.

Recently, I did my first Apple Pay at Whole Foods Market. Since Apple launched the product in 2014, it was the first time I have used it.

Surprisingly, it was very easy to use. I opened my “wallet” on iPhone and put it close to the POS, then swiped my finger print. That was it!

How will new policies influence ride-hailing mobile apps in China and what the possible strategies are

Government policies always have been a pain in the neck for ride-hailing mobile apps, not only in US, but also in emerging markets. Companies like Uber meet more and more legal problems.

Uber is involved in at least 173 lawsuits.[1] As of mid-2015, protests had been staged in Germany, Spain, France, and the United Kingdom, among other nations, and dangerous incidents involving passengers have been documented. (from Wiki)
