Mobile payments | 移动支付

This weekend’s financial math class is all about payments, in particular, mobile payments and mobile wallet💰.

Mobile wallet 移动钱包 are digital forms of wallet that people carry (or used to carry) in their pockets.  As we do not tend to carry large amounts of money in wallets, mobile wallets are convenient for small payments (as opposed to payments in larger businesses).

📳 They hold digital information about payments including credit and/or debit card, bank account, pre-paid card, virtual currency information, coupons and loyalty membership, and wallet holder identifications.📟

A mobile wallet is a software application (app) 💻that does the following:

  • Secure enrollment of the holder (application download, identification)
  • Securely store user information such as phone number, email address, and mailing address

The flow chart below summarizes the history of technology and events that evolve over the last eighty years.
