1. Because it's more accessible for more people than an Android..
2. That's not hard at all and it would be directly transferring the coins into the retailers account whereever that may be
The secondary company charges a small fee to provide a "backup" if the transfer doesn't go through and they coins cant be recovered from the purchaser
If an android phone can do it then a POS system could also do the same thing
3. Sorry to clarify it's not a credit card in that sense.. It's just a card with Bitcoins that you have.. no a card you can use and then pay back the Bitcoins with interest etc
I think that may cause an issue so I will change the topic to debit card.. my bad
why need to have a plastic card with a public key on it.
as this involves merchants having to adopt a payment system that:
reads and processes a public keys instead of credit card number
then communicates with an exchange and not a card provider.
this usually entails a second computer, card reader etc.
instead how about a retailer have a QR code and customers simply scan it with thir phone app wallet and simply pay th person.
bitcoin is suppose to get away from the credit(debt) scheme where people are playing with funds that dont exist. bitcoin is suppose to get away from leveraging and all the other methods of fake money. and instead use proper possession of value as the only means of trade.
the rules of the last centuries (pre 1900) if you dont have value to trade, you simply dont trade.
bitcoin should not go down the road of people pretending they have value to buy goods, with promises to repay later.
also to note. i have found it easy in some tests i done to fool exchanges into fake ID and as such i think that lending or having credit is a flawed business plan as its easy to run up alot of credit, and simply run off. due to the international and pseudonymity of bitcoin, the credit company wont be able to claw back any funds.
please stick with debit card system. if funds are available then trade can occur. credit is purely making funds appear out of thin are, i thought the world learnt that was a flawed method, especially now looking at the crappy position FIAT is now in due to it
