- Stripe as the first user of the SDK vs Square: For any small business starting this spring, I can't think of a reason why they wouldn't use and iPhone+Stripe to start off. Zero hardware cost (assuming they have an iPhone), no need to wait for hardware delivery.
- NFC will be coming to the iPad.
- The ability to keep the same hardware but switch payment network lowers switching cost for small businesses. Payment platforms will have to differentiate on ecosystem as well as cost.
