Is it a sin to go to a card reader?

Excuse me, but I've been pondering over this thought recently and I'd like to get your perspective. The question is, "Is it a sin to go to a card reader?" I mean, in the grand scheme of things, we rely on technology to make our lives easier, and card readers are a convenient way to pay for goods and services. However, some may argue that it's a step away from traditional methods of payment and could potentially lead to overspending or financial irresponsibility. So, what's your take on this? Is it a sin, or just a matter of personal choice and financial responsibility?
