xLED are cylyndrical tags like the xNT or xEM, except they have an LED in them instead of an nfc/rfid chip, they show where on a reader, and in which orientation a tag must be in, to be read. They show this by glowing different strengths. A weak glow is a weak signal. A strong glow is a good signal. You might want to get some to verify where and how to hold your hand/implant, as it makes a big difference.
Well, from my personal experience, The Samsung SHS-3321 works great, but it is a standalone lock and controller.
The items listed here are known to work as well.
If you’re looking for just access control readers, I don’t have much personal experience with the HF – just what I’ve said before. However, if you have an xEM LF implant, there are a few inexpensive (not the cheapested, but mid-range) that I’ve personally used, that work great. Like just wave my hand in front, without touching, and for less than 1 second, great.
This one works fantastically for 125khz – although, don’t let the description trick you, it’s not nearly waterproof. For indoor use only. There are waterproof versions on aliexpress.com though. Many of these readers come in an option HF version, and option levels of actual water proofing, so be sure to read the fine print and look carefully at the pictures on aliexpress.com … if you want waterproof, make sure they show pictures of the circuit board being fully covered in epoxy (some do show this)…
