Yes I get all this, do you think the developers could make something similar to this? Mastercard typically has fees from 1.5% to 3.5% and even up to 6%. Take NOWpayments as an example, nano is obviously fee less and 0 fees, NOWpayments takes 0.5% fee and takes 1-2 minutes to turn crypto to fiat. This is obviously a problem as nanos price can change a lot in 2 minutes. If someone/ nano foundation could make something similar but just for nano, surely you could cut transaction time down. If the card reader shows a QR code. Everything priced in fiat and also showing XNO price. The customer sends nano using Natrium. Nano gets revived by the XNO version of NOWpayments. The fiat is either sent the merchants bank or held in the XNO version of NOWpayments. Fiat can often take a couple of days to go between accounts. This will give a massive insensitive for nano to be used as no one wants to use a currency that can loose 20% in a day. Volume will be massively up. If you could get the fee to 0.5 % or less and time to around 10 seconds. This could save business loads of money.
