But there are small RFID/NFC chips some people voluntarily get for things like opening doors or storing digital info.
Here are the real, medically documented side effects of these tiny RFID/NFC implants:
Possible Complications
These are less common but can happen:
1. Infection
Any time the skin is opened, there is a risk of bacteria entering.
2. Chip migration
The chip can move a little from where it was inserted.
3. Allergic reaction
Rare, but some people react to:
- Coating materials (like bioglass or polymer)
- Metals in the chip
4. Tissue damage or nerve irritation
If placed incorrectly or too deep.
5. Rejection
The body may push the chip back out, similar to a splinter.
RFID / NFC MICROCHIPS (the ones people voluntarily implant)
These are tiny chips (grain of rice size) placed under the skin.
What they can do:
- Unlock doors
- Start a car
- Store small bits of data (like emergency contact info)
- Work like a digital business card
- Act like a keycard for buildings or gyms
- Make small payments (in countries where systems support it)
How they work:
They only activate when a reader is directly next to them.
They have no battery, no GPS, no broadcasting ability.
