Also the “125Khz RFID module - UART” has “Maximum effective distance up to 150mm”
And “Electronic brick - 125Khz RFID Card Reader” has “Max sensing distance: 7cm”
Does the 1st module really have double sensing distance?
Or is it most depending on the antenna configuration?
I want to use it with pet sub-cutaneous RFID chip, so the range is very important.
Thanks for your help.
