I have recently purchased the 1024_0 reader/writer and have been very happy with it so far. I have also purchased some blank rewritable 125Khz T5577 tags. Here is the thing with them. They come blank and I can write to them using the C# API. After writing to them for the first time I can read them and rewrite them without any issues. My problem is that I cannot detect if they are within range while they are blank. For some reason the reader won't even fire a TagEvent (C#) when a blank tag comes within range. Is this expected behavior? Is there any way to solve this?
