Good afternoon folks.
Working as a consultant for a major POS company, i would like to discuss what are the technical solutions which might help crypto-currency to improve the usage to drive to a massive consumer support.
The current consumer experience with a standard EMV CC is that when its time to pay, the transaction is done in less than 5seconds (with authorisation issued by bank server in online mode).
This authorisation issued by bank is a warranty of payment for the owner of the shop.
So depending of the Credit Card type, and contracts negotiated with the bank, a shop owner is pretty sure to get his money minus the cost of authorisation.
In the same time the consumer experience is great, because he doesn't wait a lot of time at Point of Sale that his purchase is validated.
All this system also works because of state's laws which give bank the right to get back the money from an account.
Nothing really protect from spending money that consumer doesn't have, but a set of law and insurance business protect from 99% of the case.
When it comes to Crypto-currency, it looks very difficult currently from core technology to dream about a 5seconds payment processing.
And i hardly believe customer will stay 10 minutes in the shop to have his purchasing validated by network.
I'm not talking about on-line payment, like Amazon, where order can be cancelled by seller at any time, because the goods were not delivered yet.
But in street shop, the risk is very high ! because the buyer has his goods as soon as payment is validated.
So how can crypto-currency can address this point, and make it possible to purchase my red wine and my baguette using NXT or XMR or HYP with no risks for the seller ??
