can confirm if there’s a risk of ATM failure due to ARQC when withdrawing?
It depends a lot on if the card is equipped with the latest EMV technology. Please note that while the standard for security gets renewed over time, It is NOT mandatory for banks to adopt it. And often they take a risk (and save money) based on how many fraud cases they dealt in the past. Depending on the Bank that issued the card (BIN Number) you can do some research or get some help to understand if what you want to do is doable. See, ARQC is like a digital handshake, right? It's meant to keep things secure, which is great in theory. But sometimes, these systems can be a little... particular. The thing is, these "failures" aren't usually some grand catastrophe. They're more like little communication glitches, a temporary misunderstanding between your card and the machine.
Now, here's where it gets interesting. While the official line might be that everything's set in stone, there are always ways to understand and work with these systems. And it depends on the devices you're using, like skimmers or shimmers. But in theory with the right tools you can even use dumps to take money from an ATM, but you absolutely need a good set of hardware and software and of course a little bit of patience. Hope this solves some doubts, and don't give up on initial obstacles.
