I was re-directed here by bitacer (
https://bitsharestalk.org/index.php/topic,20780.0.html). Sorry in advance that don't have a lot casual time now, so I make my point as concise as possible:
1. cell phone wallet is definitely worth doing. I still remember there was a project called limewallet that claimed to do so, but I cannot find any progress now
2. Speaking of POS, lets make this clear logically: "a POS for bts" does not equal to "commercial adoption of bts", but what we actually want is the later one, isn't it?
3. Is a POS for bts the key for stores to accept bts? Not actually. The key is a good commercial team to persuade corporations to do so.
4. Is a POS for bts necessary for stores to accept bts? Not actually. Check this out if you have not seen it:
https://medium.com/@digital654321/familymart-now-accpets-bitoex-s-bitcoin-wallet-to-buy-goods-b85c9bac78f2#.djc1n1g0ga bitcoin exchange BitoEX teamed up with familymart to aceept bitcoin to buy goods by using the small machine 'famiport'. They just added a button for this next to buttons for buying game points or other coupons. No complex software is involved, the key secret is how BitoEX persuade Famiymart to do so.
Once again, Itruely appreciate the effort to make a cell phone wallet for bts, but as to the other one, it is actually a commercial problem, not a programming problem.
