Use the M24LR as an ''active tag''

Hello,

I have a question about your M24LR products. I know the product has been designed as a passive tag, For RFID communication the power come from the reader and when we want to communicate via I2C we have to power the tag via 2 power pins (VCC and VSS). My question is :  if I power the tag myself (via VCC and VSS) and then  try to communicate via RFID. Is it going to change the read range or not ? What energy source's the tag is going to use ? I didn't see anything about that in the data-sheet. Do you have any idea if the range will be improved ? Thank you #read-range #m24lr-range-improve-power-tag #range-antenna-m24lr

Posted on July 17, 2013 at 10:43 Hello, Thanks for your interest in our product If you power the tag, the read range might be a little improved (with high power reader, big antenna...) And depending of the reader, you might not see a big difference. And like  you power the tag, the digital part will be powered earlier. I hope this might help you, Best Regards, Have a nice day, Dynamic NFC/RFID tags support
