Ask HN: Would you use a service like this?

Imagine a service that: 1. Provides you 3 NFC cards for development at no cost 2. Provides an API to those NFC cards via the web at (.02 per request) 3. Provides you with Push notifications to your server via the web (.03 per push) 4. Provides you with a square like device for reading NFC cards using your smartphone (at little, think $15-25 or NO cost) for development & $30 thereafter 5. Gives you $25 in credits for development For those unfamiliar with NFC, it's cards/tags/stickers (3/4in x 3/4in smallest form factor) that are readable by a rfid reader in ranges less than 8inches. -- Specifically, I'd like to know: 1. What sort of applications you'd build on top of this platform? 2. How do you feel about pricing? 3. Would you use the service based on these points? 4. What other questions would you have?
