Electrical – Using RFID antenna to read NFC tag

antennanfcrfid

I have a simple question, I want for a school project read NFC tags from a large range, can I use a RFID antenna to read the NFC tag ?
I want to know if the RFID antenna is going to work and read the NFC tag.

The scope will be under 50cm to 1m, it's enough (if I could get more scope, tell me).

If the RFID antenna isn't possible, could you tell me if it's possible to build a reliable NFC antenna to read NFC tags with a scope of 50cm to 1m without to need a big antenna on a truck :D, I want a small thing, that I can by example put in a bag.

Thanks for reading

You will not be able to read NFC tags with such a distance. The read distance is limited by design, and you can't easily change that.

Now there are ways to extend the useful range to about half a meter, but that's really tricky to do and part of active security research. I doubt that you want to pull that off for a school project. You need a lab and several years of experience to pull this off.

I suggest you look for other RFID tags with medium range read characteristics such as ISO15683. Their read distance is longer, but you need a huge reader-device for that.
