We will have it as vouchers / coupons. Just thought of this way of implementation. So will first have to design a good looking SFRPAY coupon and then develop an algorithm for generating unique codes on the coupon.
Much later when cryptos become even more popular, we can have hard coupons/vouchers that can be sold at stores. A much easier way to buy SFR.
Btc-e, and bter have those codes you can get that allows you to transfer coins to another user on the exchange.
Sounds like a similar concept, and could allow users to "resale" the code with out touching the coins.
Could be handy.
