WELCOME! Glad you are here.
Can you share a photo of the Honeywell readers? Do they look like this?
We have some of these at one of my facilities too, and it took me some time locating the sweetspots with the X Field Detector to get them to see my NExT. Sometimes I even have to feel the direction the NExT is sitting in my hand and present it EXACTLY where the field detector shows the brightest signal. Also, I recently found that a slow swipe up the middle from bottom to top gives me a good read almost every time. It took practice, but these are usable with the NExT!
HOW recently? You may need some healing time before weaker readers will see you. The read on these Honeywells got way better as I was several weeks into healing from the installation.
