SAICOO smart Card Reader DOD Military USB Common Access CAC Card Reader, Compatible with Mac OS, Win (Horizontal Version)

Works great, very cheap, easy to use.

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.

Plug and play, no driver needed. It seems to work fine and is light and easy to carry around. It does NOT work with VA PIV cards, which was my reason for needing one. Otherwise, it seems to be great.

[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.

11/18/14 UPDATE to my original review (see below): Saicoo noticed my review and sent me a replacement reader. On the first use, it seemed to do great -- amazing speed and no problems. On the second use, I noticed that speeds had dropped, but wrote it off to copying HD movies rather than the reader itself. On my third use, the Saicoo destroyed a week-old 64GB micro SDXC card. While the reader plugged in fine and was recognized, different cards plugged into it were not being recognized, although they were readable by my other micro SDXC card readers and by my Surface Pro 3. Stupidly, I left one micro SDXC card in the reader while I was doing something else. When I went back a few minutes later (no more than 5 minutes), I burned my fingers trying to take the card out. Apparently the reader fried my card because now it is not being recognized by any of my other USB 3.0 readers or by my computer. Needless to say, I'm NOT happy! Given my experience with two of these readers now (the original and the replacement), I can not recommend this unit. The price is good, but I've not had any trouble with my Transcend Transcend USB 3.0 Super Speed Multi-Card Reader for SD/SDHC/SDXC/MS/CF Cards (TS-RDF8K) or Anker 3.0 Anker® USB 3.0 Multi-in-1 Card Reader 4-Slots for SDXC, SDHC, SD, CF, High-Speed CF (UDMA), MS, M2, Micro SDXC, Micro SDHC, Micro SD Cards [Support UHS-I Cards ] readers, both purchased here at Amazon. Lesson learned -- and an expensive one at that given the card it destroyed. My advice: Spend a few more dollars and get a higher quality reader. ORIGINAL REVIEW: This has promise, but I guess I am the unlucky one who got a dud. Only one of the micro SDXC slots allows cards to be inserted. The other slot in the front will not allow cards to be inserted properly, as they go off at an angle and won't fully seat. I am also not getting anywhere near USB3.0 transfer speeds. I was attempting to transfer 65GB of music to the card and it was telling me it would take 16 hours! And yes, I do have USB 3.0 slots that work on my computer (they work just fine with my external USB3.0 hard drive or flash drive, for example). Speeds seem to also be variable, ranging anywhere from 116kb/s to 1.2MB/s. I tried stopping the file transfer and reinserting the reader. It started off at 1.1MB/s and then went up to 11MB/s before dropping again. I expected more, considering that I have a fast micro SDXC card SanDisk 128GB Ultra Class 10 Micro SDXC up to 48MB/s with Adapter (SDSDQUAN-128G-G4A) [Newest Version ]. I am returning the reader to Amazon for a refund, but am wondering whether others have had a similar experience, as all I see are glowing reviews. Quality control can always miss one, so I'm trying to decide whether I should try another or look for a different reader. I really liked the idea of not having to use an adapter for the card and being able to transfer card-to-card. Thank goodness for Amazon's return policy!

this is a simple, durable, reliable product. it does exactly what it is supposed to do, error free (the first such of its kind to do so, in my experience), and does so without being needlessly gold plated--something that causes extra cost, solves some problems, but would cause problems that this product does not now suffer. but because a few cards cannot really use its state-of-the-art specifications, users should feel all the more willing to use the best storage media, and keep media and reader as clean as required. (i use zip-lock sandwich bags for such, and keep index cards with such for documentation, not writing on cards, thereby risking contamination. dirt and moisture are precluded. and i'm careful about potential temperature and sunlight damage (etc.), too.) the price, for the prompt, accurate, safe delivery and for the quality product itself, was/is outstanding. eventually, if able, i may re-order, after what i have on hand might eventually be about to wear out. and tho I expect improved future industry standards will be developed, that's OK, etc. i will have gotten my money's worth by then, etc. it's worth emphasizing again that, so far, unlike some other products, no read-wright errors have been experienced with this product (in my experience), whereas i cannot say the same for certain other items ostensibly crafted to do what this product actually accomplishes. i would feel OK about using this as a modest and truly reasonable/helpful gift item, etc. and based on this item and a good 40W 5-outlet USB 12-V DC power hub from the same company, with commensurate experiences, one might (at least for now) think of Saicoo as a retail brand worth abiding interest for many careful end users--and perhaps certain others, too.

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

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.

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!
