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.

Hello, it's not an issue of the board, it can't be read continusly if the tag is always near to the antenna.

Thanks.
