HiLetgo 125Khz EM4100 USB RFID ID Card Reader Swipe Card Reader Plug and Play with Cable First 10 Digit (Only Read 125kHz ID Card, Cannot Read IC Card. See Product Pictures)

The device works as intended. It doesn’t need any drivers as it is recognized as a keyboard by any Windows, Linux or Android system, basically any computer system that can recognize the USB keyboard. In that regard, the device is very similar to barcode readers. The limitation of the device is that it only reads EM4100 or TK4100 125 kHz RFID chips and nothing else. When it does read the chip, it takes 10 digits from the chip and sends it as the text string + enter as if you would input it from the keyboard. For example, 1234567890 followed by the enter key. I have the feeling that many people do not have a full understanding that 125 kHz cards have multiple formats such as EM4100, HIDH10301 IDTECK Motorolla Indala26, Kantech IoProxXSF, AWID, FECAVA FDX-A, ISO FDX-B, Farpointe Pyramid, Viking, Joblotron, Paradox, Stanely, Keri, Gallagher and others. Those are all different cards. So if you bought it randomly just looking at 125 kHz frequency and $10 price tag, it is very likely that you may have HIDH10301 or any other 125 kHz RFID chip that is incompatible with this reader; thus, people give this product a bad review claiming missing drivers without full understanding what product is and how it intends to function. Thus you get a lot of 5 stars and 1-star reviews. The seller could indicate the product specifications more clearly and add a fair warning that the product ONLY works with EM4100 or TK4100 125 kHz RFID chips, but he does put it into the description. It is your fault that you don’t read it carefully enough. Next Dangerous things implant users as myself, can get this product to work with this reader if they have a 125 kHz Atmel T5577 RFID chip (xEM) or similar, it can emulate multiple types of cards, including EM4100, EM4200, HID and Indala. The problem may arise if you are using xEM at work with, let’s say HIDH10301 card for your door or parking access and want to use this reader at home with the computer. At the same time, xEM can easily emulate EM4100 if your workplace uses a different type of card if the idea was to use your work-cloned badge with this reader, it will only work if your work security system and thus your badge that you cloned to the implant also uses EM4100. Otherwise, you will need to rewrite the codes for EM4100 every time you want to use the implant at home and then write HIDH10301 codes from your badge before you go to work which is not very practical. In conclusion, to take benefit from this very cheap and easy-to-use RFID reader, you need to have a very clear understanding of what you are trying to accomplish, if it is some record-keeping or discount card database or any other situation where you input a unique number into any sort of database for your business, it will work flawlessly as long as your cards are EM4100 or TK4100 125 kHz RFID chips. For FOB-based access, it might be trickier to set up but possible. It will not work for Windows login access as it is recognized as the keyboard and not an RFID-reader security device; thus, the best you can do is to set your user password to the 10-digit number written to the EM4100 chip and then click on the password field and scan the chip not exactly a degree of automation your would like to have I suppose.

If you are looking for a device that works with Windows AND reads NFC RFID tags.... THIS AINT IT !!! My device was DOA and not recognized by my device manager If they would simply state: DOES Not read 13.56 Mhz range (High Frequency) NFC tags then I would not have purchased. Their support clearly has an issue understanding a simple question in English .... Does this read NFC TAGS at the 13.56 Mhz range (High Frequency) ? Note: TreverT's comments.... :The benefit of RFID instead of NFC is you can change number with a different 125Khz tag."

This inexpensive reader works really well. It is basically just plug and play. Get a set of matching RFID cards (make sure it is the exact type specified, as there are several incompatible standards) and you are ready to go. As mentioned in the instructions, the reader will transmit the card number, plus a carriage return to the USB port every time you swipe. You can leave Notepad (default Windows editor) open and capture the swipes that way. Or if you know how to program, you can send HTTP calls to a central server for further processing. Very handy little gadget!

Funciono perfectamente a la primera. Se integra facilmente como si de un lector de codigo de barras se tratara. Es mini usb, hubiera preferido un usb C. Ahora esperar ver que tan bueno sale.

Bought because I have a Dangerous Things Implant. This is a RFID reader not a NFC reader. If you have the RFID / NFC implant you need to write to the RFID side of the implant first. There is NO RFID information on your implant when you get it. The Dangerous Things reader sold on their site reads the NFC part of the implant, not the RFID part. Once I wrote a 125KHz to the RFID side on the implant this Reader works great. I used the 125kHz EM / HID / AWID Cloner from DT to write to my implant. The problem is finding a 125KHz card to read. The benefit to the RFID instead of the NFC is you can change number with a different 125KHz tag,... (if you can find one). As far a I know you cant change the NFC serial number of your tag. WORTH IT once you know.

I know I have a 125Khz card but it would not read it. It did not show any signs of attempting to read the card. Maybe you need a program to make it work, not sure so I gave it 3 stars for my ignorance. I ended up purchasing an HID OMNIKEY 5025 CL Reader for $55. You have to download drivers and a program but it will give you the hex codes it reads. You then have to convert it to see what the site code and card number really are but if you go through all that trouble, you can read an ID badge or fob.

I love how small and easy it is to use. No software is required, and the second I plugged it in it started reading my cards. I wanted something cheap and simple for reading RFID cards to log in me into my computer, and this does just that. All I did was set the ID number for the card as the pin, and now each time I tap my card on the reader on the pin sign in option, it logs me right in! This is also great for just identifying card numbers and other things like that. Totally recommend!

I’m not unfamiliar with rfid cards and fobs. I have an rfid reader writer that works great, wanted to store a list of my pre-programmed cards, this thing beeps when you plug it into usb port but that’s it , not another chirp and does not read a card or fob . Plug and play (pray) it says on the landing page. I opened up notepad to capture text but doesn’t send anything out , am I missing something here? It’s not rocket science.

Ne convient pas à mon système

Esta lectora se conecta por USB a la computadoras e inmediatamente funciona, puede usarse la aplicacion de Excel, Worpad, Notepad y cualquier otra aplicacion, ya que su funcion es que en vez de capturar manualmente el numero de serie de la tarjeta, lo hace automaticamente y muy rapido, hace un pequeño pitido cada vez que lee una tarjeta y se pone un led en color verde indicando que ya la leyo. Esta lectora es solamente para tarjetas o llaveros de frecuencia de 125 Khz y en este caso la adquiri para que leyera a 10 digitos., hay otro tipo de lectoras para diferentes digitos, dependiendo la cantidad de digitos en el numero de serie que tengan sus tarjetas. Lo recomiendo y su costo es economico

Lo compre mal pensé que era clonador no me funcionó
