Eneni Bambara Abban, a robotics engineer, has flexed on Twitter about one of her innovative ideas. After being served a drink by a robot bartender, she paid for her drink with her nails, which have a chip in them.

Watch the demonstration below:

Abban detailed that the chips embedded in her acrylics are NFC-powered.

What does NFC stand for? Near-Field Communication.

“Middle three fingers have NFC powered LED circuits only and my thumbs have Re-writeable NFC powered data tags one will be used for payments and I think the other thumb I’ll put contact details for when I’m at events and want to quickly connect with someone,” she explained.

When asked whether NFC payments are writeable to any NFC chip, she shared a further look into the process of having a similar innovation to hers.

“Nope definitely not any. Memory is a big factor. The payments do require a security protocol & payment system but once you’ve got enough memory (from the data chip itself) linking is easy. I always recommend fidesmo pay if you wanna try it out as it’s made for wearable tech.”

Abban is the founder of The Techover Foundation — a global edutech NGO that works to educate the next generation pursuing STEM, especially in underserved communities.

In October, the technologist was recognized for her work in “developing computer vision algorithms for self-driving cars to data analysis and optimization for some of the biggest gaming apps in the world.”

Additionally, Abban has supported over 30 coding and robotics workshops in Africa, the United Kingdom, and virtually.

After almost dropping out of robotics because of imposter syndrome, Abban champions young Black girls to pursue STEM. As someone who experienced being the only Black girl in her class, she understands firsthand the importance of representation.
