Hello there, new person here. I was using the MFRC522 RFID Reader in a small project of mine, and I am using the tag instead of the card to trigger the reader. My question is that will the reader be able to read the tag from a distance of maximum 5cm, like the datasheet says or is an external antenna required?
Warm Regards

If assembled properly I see no reason why it would not work.
Hi there. A few forums I have been to indicate that an external antenna is required to extend the range (obviously), but those distances are >10cm and more, while mine is just within the in built functioning range, so technically.... should be as you said right?

Ok so, I've tried assembling the reader, with the help of Adding AttennaOff and get/set of AntennaGain by mdxs · Pull Request #47 · miguelbalboa/rfid · GitHub, I manage to increase the read range from 1cm to 2cm, but is it possible to increase it further to around 4cm, as the datasheet says? Or is an external antenna/reader such as 13.56MHz 8cm RF Module External Round Antenna Coil Diameter 12.3cm 6256299357033 | eBay is needed?
