Lightening N Logo // Has anyone see this?

[graphicgirl]

I'm a graphic designer and I have a client who is inspired by this logo / notification - only problem - I have no idea what it is. Has anyone seen it and could help me identify? I want to make sure we don't accidentally design something too identical to another's intellectual property.
Thank you!

Seems like a weird version of Facebook's Messenger's logo... are they using a theme?

Kind of looks like an NFC logo.
