The invention includes a pre-programmed scannable implant inserted just beneath the skin and relies on "near-field communication" (NFC) that phones already use to send data for various activities, such as making payments.

The company's Chief Disruption Officer, Hannes Sjoblad, said that implants are very versatile technology, and it is very convenient to use them to have one's COVID passport accessible at all times. This comes as governments continue battling the coronavirus pandemic by forcing citizens to get inoculated and pushing its "effectiveness" in battling the disease, especially with the omicron variant leading to a surge in COVID cases.

With more and more U.S. cities issuing mandates for people to be fully vaccinated to go to work and attend social events, the new chips can be useful in utilizing technology, as it is similar to the use of contactless card readers.

"This means it is always accessible for me or for anyone else, really, who wants to read me. For example, if I go to the movies or go to a shopping center, then people will be able to check my status even if I don't have my phone," Sjobald said.
