ATMs in her world are pretty vulnerable to magic. 

Yeah, that'd do it.

If ATMs here are designed to be hardened to superpowers, though, she might need to think up something else...

Not so much hardened, though the newer generation models have some of that too, but they've got cameras and monitoring software with algorithms that trigger if the usage patterns go too far outside expected parameters.

She can get past ordinary cameras - but, yeah, she might have to be careful to only skim a bit of cash at a time, at least if she doesn't want the heroes knowing she's doing this. On the other hand, if she physically breaks the machine open rather than tricking it into giving her its cash, she can at least get any cash currently in it. 

As long as it doesn't have a flash-trap. Burns the cash up if the safe box is opened improperly.

Fire's her thing, so should be doable to check for - and possibly just flat out disable. 

Just don't burn the city down.

"I don't lose control of fire, trust me."

"Yeah, yeah."

"Might start out with another city, too; usually I'll bounce around some. And that'll be a good test of my ability to go unnoticed - I'll fly somewhere and see if anyone tries to Intercept me. - Maybe not reliable long term, but it'll help if I need cash before I get settled. Back home I've got a list of wealthy accounts whose owners I swear never check their bank statements..."

"Just make sure you're back in time for the next bank robbery. An afternoon out is much better than one filling out witness statements."

Giggle! "I'll be quick."

"Though, speaking of - are you gonna get in trouble for not sticking around to give a statement?"

"Ugh. Maybe. Depends how well my boss can bullshit the PRT."

"I can pretend I kidnapped you... But that might just make more paperwork."

"Yeah. If I give them some info about you, they'll probably get off my back."

"As long as it's flattering, I'm okay with that."

"I'll make sure they're impressed."

"Thanks!"

"And give them your full name, since they'd come up with something boring otherwise."

"Can't have that."

"Least I can do, really."

"I still appreciate it!"

"You're welcome."

Hum. "So the PRT are like police?"
