Ubiquitous Bluetooth and PAN - Personal Area Network

[Michigan Swamp Buck]

Without looking into the operation concepts  of nano circuits capable of digital communication, I suspect it may work like sub dermal micro-chips that operate with a system known as Near-field Communication. This requires a very close intimate  range to function, however, it may be possible to create a high powered directional unit that could work at a greater distance.

NFC is a set of short-range wireless technologies, typically requiring a separation of 10 cm or less. NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s. NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target. This enables NFC targets to take very simple form factors such as unpowered tags, stickers, key fobs, or cards. NFC peer-to-peer communication is possible, provided both devices are powered.[54]

NFC tags contain data and are typically read-only, but may be writable. They can be custom-encoded by their manufacturers or use NFC Forum specifications. The tags can securely store personal data such as debit and credit card information, loyalty program data, PINs and networking contacts, among other information. The NFC Forum defines four types of tags that provide different communication speeds and capabilities in terms of configurability, memory, security, data retention and write endurance. Tags currently offer between 96 and 8,192 bytes of memory.

Microchip implanted under the skin could be your COVID vaccine passport

. . . The chip uses near-field communication (NFC) to send the data to devices, including smartphones, that can read them.
It’s the same type of technology used in most contactless credit cards and mobile payments, according to Fox Business.
Such devices have a range of practical applications.
“They can act as a key fob or a form of payment, or they can be programmed to store data, like, for instance, your resume. (All you have to do is hold a smartphone over the chip to program it.) ,” according to Hour Detroit Magazine. “They’re not dissimilar from the identification chips you’d install in your cat or dog.”

. . . Many responses to Friday’s video were negative and angry.
Some noted that involuntary microchipping via vaccination was a prominent conspiracy theory last year.
A poll taken in May 2020 found “44% of Republicans think Bill Gates is working on a coronavirus vaccine because he wants to plant a microchip in them and monitor their movements,” the New York Daily News reported.
