USB A CAC Smart Card Reader, (Horizontal Version)

Works for on a HP laptop running Windows 10 perfectly. I travel for work and it gets bounced around quite a bit. After a trip it quit working about 2 weeks after I bouhght it. I requested a return and it was replaced for free. Good seller, product works. Best part - this was the cheapest CaC reader on Amazon in January 2026.

I picked up this Saicoo CAC reader to access military sites from home, and it’s mostly been a win. Plug-and-play on Windows 10? Check. No driver headaches? Check. Sleek black design that makes my desk look more official? Double check. The reader works well for most secure logins—think AKO, OWA, DKO, and the like. It’s compact, easy to use, and gets the job done without any drama. However, there are a couple of caveats. Some users have reported issues with Mac compatibility, especially when using newer USB-C ports or certain browsers. Additionally, there have been concerns about the drivers containing malware, so I’d advise downloading them from trusted sources only and scanning them before installation. In summary, if you're looking for a budget-friendly CAC reader that does the job on Windows, this one fits the bill. Just be cautious with driver downloads and check compatibility if you're on a Mac.

[UPDATED REVIEW] Wow!! After writing the below one star review Saicoo contacted me to make it right. They credited me the amount of the damage SD card so I could get a replacement and sent me another unit to try out. I don't have to tell you how rare it is to find a company that will do that. They deserve your business. IMPORTANT TECHNICAL UPDATE: The card reader works fine, the problem is there are no instructions and the stencils on it are difficult to understand. That is why my micro SD card got stuck, it was oriented incorrectly. DO NOT insert a micro SD right side up (pins down) in the end port or it will get very stuck. I suggest that Saicoo change the stencil on the side to show pins on the SD card icon and change the stencil on the back to show pins on the Micro SD card icon. This would correct the confusion. Here is the correct way to insert the cards: SD Cards: Must be inserted in the side port upside down (gold pins up). Must be inserted in the end port right side up (gold pins down). Micro SD cards: Must be inserted in the side port right side up (gold pins down). Note: about half of the Micro SD sticks out. Must be inserted in the end port upside down (gold pins up) Note: it goes in very deep and only 1/8" of the Micro SD sticks out. <<<>>> Original Review: This product is flawed, poor design or bad QC. I didn't even get a chance to see if it worked. I opened the package gently inserted my new 64 GB micro SD in the end and that was it. It was stuck, as if it had been glued in and could not be removed. I was so concerned about removing it that I forgot to even plug it in and see if it worked. To make a long story short the $20 micro SD card was destroyed (along with my personal files stored on it) while trying to get it out; it broke into pieces. Afterwards, I did try the other ports. The side Micro SD port accepted the broken Micro SD without jamming, both standard SD ports (end & side) took the SD adapter without jamming, but the end port is not properly aligned with the hole and is deeper than the side one causing the card to get jammed. I will contact Amazon returns for a refund for this reader, but what can I do about the $20 Micro SD that was destroyed because of it? Saicoo should cover the damage that their product caused. <<<>>>

I ordered this "Saicoo USB 3.0 11-in-1 SD Card Reader" after browsing through several other similar items on Amazon.com. I chose this card reader because of its low price and the large number of very positive reviews it has received. I primarily use it with my Windows 10-based laptop in order to transfer large JPG and video files from my digital camera and smart phone's memory cards to my computer. In every case so far, the card reader has performed flawlessly. The Saicoo 11-in-1 SD card reader has four slots: two for full-size SD cards and two for micro SD cards. I tested each card reader slot in each of my laptop’s three USB ports. They all work perfectly. They respond almost immediately when I insert the card reader into a USB port, and they transfer data as quickly as the SD cards will allow. I especially like the rugged construction of this card reader. It’s sturdily built, and is just the right size for the somewhat cramped space where I use it. It’s very convenient to use. The USB cable on the reader is of very high quality, although I think it might have benefited from being a couple of inches longer than it is. I am very pleased with my new “Saicoo USB 3.0 11-in-1 SD Card Reader.” It gets my highest recommendation.

Works great!

Très bon rapport qualité prix, les SD de 128Mo sont lus sans difficultés. Je recommande l'achat de ce lecteur sans hésitation

Purchased this in March and it worked fine, but unfortunately after 7 months the device stopped working. I tried changing to different USB ports, but the blue power light no longer lights up and the device is not recognised by the computer. The device was used mostly for SD cards and micro SDs, and was never transported from one place to another. I am a bit disappointed that it broke so soon, as it appeared to be built pretty solid. ------- Updated: The seller contacted me to offer me a replacement shortly after posting my review. I am very pleased with the customer service, as I did not expect to receive a replacement. Because of thi,s I have updated my rating to five stars as this encompasses my overall experience with purchasing this product.

FÜr die SD Karten bestens geeignet. Top GEschwindigkeit durch 3.0 Anschluss. Auch nach 8 Jahren immer noch im Einsatz

Voila un petit lecteur de carte bien pratique et en USB 3. Chez moi ça marche parfaitement mais je n'ai pas d'USB 3 sur mon ordi. Je testerai ça chez un ami et vous dirai si le débit est bien à la hauteur de ce qu'on attend. L'intérêt pour moi était sa connectique très fine avec son petit câble. Sur ces chers ordis à la marque pommée, les ports USB sont très rapprochés les uns des autres et les lecteurs de cartes avec le port USB moulé dans les bloc plastic obstrueraient l'ensemble des ports USB. Ici tout reste accessible! Donc très bien!

Works great after I manually installed the included driver. Running the driver installer did NOT fix anything in my case, since even after a reboot it was still using the (broken) default Windows driver. Once you get it installed correctly, the device appears in device manager as "Realtek USB Smart Card reader" and works well.
