as in, my card does not need the connection, but the store needs a reader connected to the blockchain? So it's an option in an environment where the customer has no phone, but internet service does exist. Which makes the meme the article has in it a bit misleading, because it is true that if the internet falls/gets cut/whatever, our sats are stranded on a blockchain which still produces blocks on the other side of the world, but we can't interact with it....
