Can I use my phone to get money from ATM without card?

I'm curious, is it actually possible to withdraw cash from an ATM using just your phone, without needing a physical card? I've heard about mobile banking and digital wallets, but I'm not sure if they extend to ATM transactions. Could you clarify the process and any requirements or limitations I should be aware of? It would be really convenient if I could skip carrying my card around all the time.
