Increasing the range of RFID Reader along with multiple tag reading

Hy All!

I wanna to increase the read range of my RFID reader RC522 or SM130 or I can use any other HF (13.56 MHz) reader that you can suggest me, I can use that.

Along with this increased range I also wanna to read "multiple tags" "simultaneously" too!

Anyone who has worked on it, Please help!

I need help!!!!!!

The ability to read multiple tags is a property of the reader. This is a property that your two readers does not have. You also need special tags even if the reader did have this capability. It is known as collision avoidance and is normally only found in UHF RFID systems.

Increasing the range is just a matter of a larger coil but tuned with capacitors to the same frequency. To do that you need at least an oscilloscope.
