"How will GRAFT's RTA system allow merchants to operate their businesses as usual? What is the benefit of having software that can be integrated over existing commercial devices? What will be the impact for merchants and customers that have the ability to pay and sell for any form of payment? How do you imagine the integration of GRAFT by changing the way we interact with crypto? How will RTA change the future of crypt?

I will respond taking into account the current situation of my country Venezuela

Venezuela is going through a brutal economic crisis, where there is not even cash in the banks. The little cash you get in a bank only serves to pay for a bus or taxi to take you from work to home or vice versa, but to buy food, clothing, shoes, or any material product is not enough and you must resort to using your card debit or credit to cover the expense.
But what happens if I cover the expense with the credit or debit card and not with cash?

Example based on dollars, our local currency is BsF:

A product purchased with cash may have a cost of $ 1 but if you buy the same product with the credit card or the value may be double or more, that would cost $ 2 or up to $ 3. All this due to the same inflation and that the government allows these actions. Then as you will see it is better to buy everything with cash only to get so much cash is almost impossible. On the other hand, every day our currency loses value and the worst of the case is that the prices that are handled here are based on US Dollars but your earnings are in Strong Bolivares (Local Currency). Every day the demand of the Dollar rises, and if you have savings in Bolívares Fuertes lose value constantly. Today you can buy 1kg of coffee in 10,000,000 BsF. that is equivalent to $ 3 more or less, but if you leave to buy another day and the dollar increases its value, you can not buy 1kg of coffee because its price will rise automatically. It is impossible to save.

Graft arrives at the best moment, hopefully here in Venezuela adopt this technology soon so that all of us who are in the world of cryptocurrencies will not benefit from it. In what way? We will not have to change our Bitcoins or cryptocurrencies to FIAT money and this way we will never be devalued, we will be able to save much more because they will not charge us commissions in exchanges or buying and selling. For example, if we have steem or sbd we have to change it to BTC or another cryptocurrency and then change it to Dollars or local currency and those transactions are a lot of profit to pay the fees that each platform has. Any entrepreneur investigating and analyzing Graft will realize that their business will not be altered when implementing this technology. It will attract more clients since Graft guarantees you speed in transactions, something that in other projects you will never get. Nor will it be difficult to integrate the system, since the same system comes with everything ready to work in any point of sale. Generally speaking, graft can make a big change in the world of cryptocurrency. Just imagine going to the supermarket and buy directly with BTC, then go to eat ice cream, or go to the movies, buy tennis, clothes, buy your plane tickets for a trip and pay with Ethereum. This would be incredible, we do not need to be changing FIAT money every time to make your daily expenses.
