There are multiple categories of mobile apps that send USD. The categories are:
- Mobile banking
- Mobile e-commerce
- Mobile money transfer
- Mobile payment
Excluding the mobile banking apps (which nearly every major bank offers) and the B2B and B2C-only mobile payment apps (e.g., the Starbucks payment app, Google Wallet, TabbedOut, Jumio Netswipe, LevelUp/Scvngr, BokU, etc.) then your list also would include:
4.) Serve (AmEx)
5.) Dwolla
6.) Venmo
7.) AlertPay
8.) Skrill / MoneyBookers
9.) Clover
10.) HyperWallet
11.) Slash8 App
12.) Klunki
13.) KuaPay
14.) OpenCuro
15.) Boom (m-Via)
16.) Square
17.) GoPayment (Intuit)
18.) PAYware (Verifone)
19.) Stripe (to some degree can be P2P)
20.) WePay (to some degree can be P2P)
And that's just USD or primarily for the U.S. Then there are:
21..) PayFirma (like Square, but Canadian)
22.) PingIT (Barclay's - UK)
23.) OboPay
24.) M-Pesa (Kenya)
25.) AirTel App (India)
26.) GCash (Philippines)
27.) Smart Money (Philippines)
and ... oh, a slew of others around the world.
The one thing they all have in common? They are all basically methods to do what banks themselves haven't been doing. They exist to reduce some of the friction of working with the banking system. Some day they'll see major competition from apps that link to bitcoin (or will incorporate that functionality themselves.)
