RFID Reader 125KHz - Reads Proximity Cards & EM4100 ID Card - USB Reader Emulates Keyboard for Linux, Android, Win, iOS

The reader works perfectly. I have a prototype project I used this for and I could see so many applications for it. The reader will write the Id number to the connected device, in my instance to a field on a webpage. It automatically presses enter after entering the card id number. Perfect identity or access tool.

Works great, company uses Hirsch products and needs a seamless and cheaper integration solution for enrolling credentials. This worked like a charm. Using the second option of Facility Code + Card ID numbers with a space between and enter being applied. This works flawlessly. I did note and why I dropped it down a star, silicone wrist band type credentials sometimes wouldn’t read, but this was when device was plugged into a hub or docking station. When directly plugged in it had no issues reading these items. I have ran approx 500 reads against it and had only slight delays. I’ve also tested on 3 different machines and only item of problem was noted wrist bands being problematic when hooked up to a hub or dock. I plan to order more and get them in the field for further testing. Great product.

Worked just as described. Read all my RFID cards perfectly

I wanted to use the product for a Meals on Wheels food distribution site. Besides getting different numbers on different readers AFTER POWERING OFF FOR THE NIGHT. It no longer sends a return after the read. Without the return I can not do an auto look up. We were preparing to make it a center part of our operation. With its flaky operation we can't. Yesterday I asked for help. I will report back. UPDATE After powering off system It seems to sometimes lose its configuration. You will need to reconfigure at times to get all readers to sync on same setting.

Needed something not to expensive for a project where we already used HID badge cards. units worked perfect out of box no need to install software or drivers and also worked in my android phone. for someone like me with no experience in RF ID cards it was very easy. If you need to change the number format then it requires more knowledge on how is choose and configure the right format for you.

Once plugged in, I could never get it powered on long enough to configure it. If I push the USB cable into the reader and hold it, I can get it to the configuration menu. Once I let go of the cable the reader powers off.

The biggest thing to determine before purchasing one of these RFID readers are the specifications of the card(s) you plan on reading. They all physically look similar, but the technology for reading the information is different. Our cards use format 51 (advanced config) without prefix/suffix. As another reviewer stated, the instructions are a little confusing, but after reading it over a bit and playing around with a little guess-and-check, as long as it spits out some data the first time you use it, the card is most likely compatible with the RFID reader...you just have to figure out the configuration. I give it 4 out of 5 stars due to the instructions. If the instructions were easily understood I'm fairly confident I would have had it properly configured in about 5 minutes. Unfortunately due to the confusion it took me about an hour. Still not bad considering it works, and it works well. The software-on-board configuration was a uniquely interesting way to program it too, which -even if clunky- I actually like; no possibility to lose the software or user manual!

It reads 125khz cards i had also the two other cards came with as bonus
