Some people have described the competition for business owners in the mobile payments segment as a "race to the bottom" in terms of credit card processing fees. Indeed, there are now at least 10 mobile payments or POS vendors targeting small businesses that are undercutting traditional credit card processing fees. The include LevelUp, Groupon, Square, PayPal Here, GoPago and others.
Clearly this is not the company's long-term strategy. It's trying to create more bar "inventory" for consumers in the hope of driving app adoption and expanding beyond San Francisco, it's only current market. However the zero credit-card processing fee is a major incentive for bars to sign up and use the system.
Coaster is another example of something I've written about multiple times: vertical or point solutions that offer self-evident value to consumers and will drive adoption of mobile payments. My favorite example is mobile parking payments but Coaster is a pretty good example.
By using Coaster smartphone owners can order, pay and tip at bars without giving over their credit cards directly or waiting in line. I've not yet used the app myself. However Coaster offers concrete and obvious value for bar patrons (and bar owners).
These kinds of vertical scenarios or "point solutions" will educate consumers and get them comfortable with mobile payments, paving the way for broader adoption of "horizontal" solutions such as Google Wallet. Exposure to a positive veritcal payments experience will tend to accelerate broader payments adoption.
By contrast people often don't see the reason or need for "mobile wallets" in the abstract.
How interested are you in using your mobile phone to pay for things, and replace cash or your credit cards?
