A woman who goes by “CHIP GIRL™️” recently shared a video of herself allegedly purchasing groceries using a chip implanted in her hand, which she originally had inserted as a security mechanism.

The woman, Burgundy Waller, has amassed a TikTok following of 4.8 million followers and often posts about having a radio frequency identification chip implanted in her hand. She had the implant put in between her thumb and index finger, according to Unilad.

“Chip Girl” reportedly first got the chip installed as a replacement for having to use keys in her front door and household cupboards.
