    Exist any cheap option to be able to detect and recognize in a range of 10 Cm?

      Hi guys,

       

      I want to detect my cats and recognize them so I test first with the RC522 RFID LF reader but the range is so small that I couldn´t detect my cats when the tag is not on the right position or when they eat in a different angle

       

      I'm looking for a different option to replace this option but the prices rise a lot. I'm considering the possibility of using an antenna DIY (this test didn´t work, unfortunately), or buy one but is so expensive.

       

      I'm considering different technologies as NFC (Near field Communication) and Proximity Beacons

       

      Do you guys have any suggestion for me?

      I'm looking for an option around 5Us.

       

      Thank you so much for your help
