I am trying to achieve read range of 10cm or more on an antenna attached to M24SR chip. I am currently getting a read range of 5.5cm How can I increase the read range?

Thanks in advance.

​Hello Anish,

RFID systems are based on a magnetic coupling between reader and tag. As a consequence performance depends on different factors like reader power, reader antenna and tag antenna.

what kind of reader and tag are you using now? Can you give us more information about their characteristics.

A detailed description of your system constraints  is welcome so that we can help us to improve its performance.

waiting for your feedback,

NFC/RFID support team.
