Multiple Antennas with 1 single NFC processing station

Post by dealerloot »

Dear Engineer,

Is is possible to use multiple NFC antennas (around 64 or 128 antennas installed at different locations) to read various NFC tags with a MUX setup so that each antenna is powered, polled, read in a particular sequence and the data can be gathered at a central processing circuit. Can you please suggest an adafruit product(s) to work with this type of project.

Any input is appreciated and I thank you in advance for help.

-Bobby

No. That really is not possible.

Is it possible to get a NFC reader module where the antenna is separate?

Worst case scenario, can the antenna from the NFC reader module/shield be cut and hooked via external wires? In principle this should work, but I'm not sure.

I thank You for your help in this matter.

The NFC readers available in the market have the antenna and processing circuit on a single PCB. I want the antenna separate from the circuit so that I can hook multiple antennas using one data/ power center.

In theory, the PCB boards currently available can be broken or cut to separate the antenna. The antenna can be hooked via 2 wires to the processing circuit. I just wanted to avoid cutting a PCB board and voiding the customer service in case of technical issues.

Then you will have to look elsewhere because Adafruit does not (at this time) sell a NFC device with a removable antenna.
