A microchip technology introduced in recent years by the Stockholm-based startup, Epicenter, is being presented as a means to store one's COVID-19 vaccine passport under the skin, according to a video from the South China Post that went viral Friday, Fox Business reported.

The firm has showcased an implant capable of storing a COVID passport that can then be read by any device using the near-field communication (NFC) protocol, according to the video.

The video featured Hannes Sjoblad, founder of the Swedish Association of Biohackers, advisor, and speaker on Human Augmentation, and ambassador for Sweden at the Singularity Universe.

Sjoblad demonstrated how Epicenter's rice-sized microchip, has been adapted as a COVID-19 passport, which is implanted under the skin either in the arm on between the thumb and forefinger.

The technology the company uses is called RFID or (Radio-Frequency Identification), which uses electromagnetic fields to identify electronically-stored information. The chips also use near-field communications (NFC), the same type of technology that is used in most contactless credit cards and mobile payments.
