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. 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. 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 FDXA, 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, it is very likely that you may have HIDH10301 or any other 125 kHz RFID chip that is incompatible with this reader. Description: Note: ID card reader can read the top 10 digital bit. Size: 110mm*80mm*26mm - USB cable connection to PC (Plug and Play, Driverless for Windows 2000, 2003, XP, Vista, Windows7, Linux) - Can read all 125Khz RFID EM4100 EM410X Card/Tag - Diagnostic Power LED - Built in operating buzzer - Output format: First 10 digit - Powered from USB, does not require any external power supply. - Easy usage - Compact design. Package Included: 1 * 125Khz EM4100 USB RFID ID Card Reader with USB Cable Review: The RFID reader works as keyboard device and only with EM4100 and TK4100 cars and fobs - 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. Review: Only compatible with older versions of Windows - This uses drivers that newer versions of Windows can’t read. Windows dropped the support a while back. I’m using Windows 10 and it won’t work. Not sure how far back you have to go for it to work. Probably works with XP, but I don’t have a machine to test that on. ## Features - Only read 125kHz ID Card, CANNOT read IC Card.
