dear SirI have a problem with a reader application, because usually the client enters inside and put the RFID tag inside a box in proximity of the antenna, but if the tag is always in the same position respect the antenna, the reader reads it only the first time. So becouse I have to check continously the presence of the tag to solve the issue I have to disconnect the power supply and periodically reapply to the reader.Question by: admin on 2018-12-18 02:21:29
<p>Dear Sir, I solved the issue powering down and powering up the module, every each power on it reads the tag correctly. Best regards </p><p><br></p>Answer by: admin on 2018-12-18 02:21:29
