Most NFC based payment systems (google, apple, samsung) require an NFC enabled POS device. Can we not simply use an NFC sticker instead? What are the challenges I am missing to see? Can someone in the forums point me to a relevant article/experience. Most grateful!

My university has made it compulsory to buy coupons for breakfast, lunch and dinner for 20 days every month. So a lot of students who buy them have spare coupons left. Others dont buy any, and end up borrowing, buying from each other. I would like to build a bidding system, so people can buy and sell coupons there. I have code for login, and am restricting to my university domain. How can I keep an open market, and let the bidders choose the current market price?

Thanks for any thoughts, suggestions or comments.

Hello hackers, I am working on an idea to create large text content on specific subjects. I plan to recruit 20 or so domain experts. Can I set up a backend that looks like wikipedia for these guys to create/edit these articles/content? I hope my question was clear.
