How to reduce the power consumption in polling MFRC523 ?

[waynechung1]

I have some question in polling MFRC523.

I use 2 second timer polling mfrc523 to detect card, but the power consumption is not good.

How can I set this RFID chip ?

If you want to reduce the power consumption during polling, you may increase the antenna target impedance but that will decrease the performance(working range). so better use a RF chip supporting LPCD, such as CLRC663 plus.

Have a great day,
