Unless you know it, a wireless SD card sounds almost contradictory. After all, it is not as if you had to connect your SD card with a USB cable as you would with an external hard drive. We are used to simplifying devices such as headphones or routers by removing the cables, but is there any way to simplify a Wi-Fi SD card?
In this example, we are not really simplifying SD cards. We are making them more advanced. Wireless SD cards are a unique combination of two devices in one. They are a SD card of a part, a wireless card of a part. When Eye-Fi first came onto the market years ago, consumers were impressed by the concept. But very little apart from the high-end DSLR cameras it backed them up.
Nowadays, wireless SD cards are compatible with almost all consumer devices on the market. And even if your device does not support wireless SD cards, many of them are designed to connect directly to your computer. When configured correctly, you can skip the cloud and back up all your important images automatically.

What is a Wi-Fi sd card and how does it work?
An SD card is a device that allows you to transfer photos and other types of files between different devices. It requires that you uninstall the card from one device and mount it by the other. Alternatively, you can connect the two devices through a cable connection.
The SD Wi-Fi card, on the other hand, eliminates all these problems and makes communication between two devices possible through a wireless connection. This is possible even if the device containing the SD card does not contain Wi-Fi capabilities. In other words, it can be compared to a standard SD that comes with a wireless adapter as an auxiliary.
More on the Wi-Fi SD card
The Wi-Fi SD card is a simple device that contains two sections and works in a very simple way. There is a section that works as SD and another that works as a wireless adapter. The section that works like SD is the part that you insert into your camera, tablet, computer or phone. It is the section where you store files and other media.
The part of the wireless adapter is the one that allows you to connect your SD card to a different device to transfer data between the two. For the adapter to work properly, you must download and install a compatibility application on the device where you want to transfer the files.
- Capacity of the SD card: SD Wi-Fi cards come in many varieties and vary in size. The sizes range from 8 to 32 GB, which allows enough space to store as much data as necessary. To further increase storage space, it is also possible to purchase an SD adapter that has a MicroSD card slot where you can repair another SD card, giving you storage space of up to 128 GB. However, we advise you to check all the features you need before opting for this option, as some SD cards may not be compatible in that arrangement.
- Card size: One important thing to consider is the size of the wireless SD card, as they come in different sizes and capacities. The MicroSDs are the smallest in size and are perfect for use with smartphones. The MiniSD is the second largest and was initially introduced to the market for use also with smartphones, but then they were replaced by the MicroSD cards. The standard size SD cards are the largest and are best for use with digital cameras and some selected tablets.
- SD card class: SD cards come in different classes; UHS, 10, 8, 4 and 2, the class being a representation of the operating speed of the SD card, with class 2 having the slowest speed.

How to choose a Wi-Fi SD card?
You may not know what to look for when choosing a Wi-Fi SD card, but some of the most important things to consider is what has already been mentioned in terms of size and capacity. The other consideration is what use the card needs, as well as your budget.
If you want to use the card while on vacation, it is best to buy a large SD card in terms of size so you can store all the photos you may need while you are traveling. This is especially true if you want to make videos during your trip. If you already have existing SD cards, we recommend that you only buy a Wi-Fi adapter.
The best Micro SD WiFi memory cards of 2018
Let’s take a look at the three best Wi-Fi enabled SD cards in the market by 2018. We’ll see what has improved in the last generation and give you examples of how they can be used.
Toshiba Flash Air II
Toshiba has been a player in the global storage market for many years. But this is not their only area of expertise, they also produce everything from laptops to televisions and even medical equipment. Their products tend to achieve a balance between affordability and reliability, which makes them an excellent option for most consumers.
We are used to seeing SD cards in black, so the Toshiba Flash Air II looks very nice. The plastic is a bit stiffer than we are used to, a strong indicator of durability. While the framework is unique, the logo is quite simple. But its purpose still serves well. It has all the information you need about the card on the front, so if you have a stack of SD cards killing, you will always know what devices it supports.
The Flash Air line of wireless SD cards is available in two varieties. Most users will want to choose the 32 GB version, although a 16 GB model is also available if you have a tight budget. This is an SDHC card, so it is compatible with almost all modern devices on the market. However, that means that the storage space will be restricted to 32 GB until Flash Air III reaches the market in a short time. Technically, this is actually a microSD card in a standard SD box. Its advanced wireless transmitter takes up most of the space in the case. Fortunately, your devices can not tell the difference.
Although many more devices support wireless SD cards, there are still some that do not. Toshiba addressed this problem by creating a card that was unique in functionality. Instead of acting as a client and connecting to your existing network, it does the opposite. The Flash Air card really works like a server. You connect directly to the card and download your files in that way. All this is done through the mobile application. This application works very similar to the gallery on your Android phone. You are provided with a list of all the thumbnails of the images or videos on the card. Once you touch one, the phone will connect briefly to the card and download the full-size file. This only takes a few moments and the design guarantees that you can use this card with any SD compatible device.
Use of energy
Storage only SD cards use a negligible amount of energy. But when there is a wireless connection involved, the battery life of whatever the card uses may be affected. First generation products really reduce battery life by up to 50% when in use! Fortunately, those days have been left behind. When in use, the card uses between 2.7 and 3.6V. The variation is due to the fact that the card can dynamically adjust the signal level depending on how far it is from the card. If it is right next to you, the wireless network will work at lower power. But if you are far away, you can expect a higher energy consumption.
But this energy consumption only takes place when the card is actively used. When files are not transferred, it shuts down the wireless network and enters a kind of low-power state where it draws current until it is needed. This means that there is a bit of delay from the moment you request the files until you receive them, but you can enjoy a longer battery life.
This is the company that started everything. But today’s Eye-Fi is nothing like the first model that hit the market many years ago. The product has gone through several improvements, which has led to the high quality card you see today. This is not the only product they have on the market, it is the entry level version. If you are not completely sure of what you need, start with this card. If that is not enough for you, you can scroll down to read about your updated model.
From the moment you look at Eye-Fi Mobi, you will know that it is not a common SD card. Eye-Fi made this card in its characteristic orange color, and highlighted it with a bright and cheerful label and a small white writing lock. “Mobi” is in front and center, with the printed size below that. This brand is considered the Cadillac of the world of wireless SD cards, and it shows.
Since the card is aimed at photographers and videographers, it is rated for the same class 10 performance you need. This model is specifically designed to handle image and video files, and includes support for .mpg, .mov, .flv, .wmv, .avi, .mp4, .mts, .m4v and .3gp in the video department. If you want to transfer image files, you will want to stick to Jpegs. It also supports the latest network technologies, including WPA2-PSK and 128-bit PSK.

The basic Mobi reading and writing tests were quite comparable to the Toshiba card. In the best case, it observes an upper limit of 20 Mbps of reading and 13 Mbps of writing. But since this card uses its own wireless network, we can compare how fast files are transferred and not just saved. If you are shooting 6-megapixel images (which are approximately 3 megabytes in size), you notice a 6-second delay from when the photo is taken and until it appears on your laptop. With 12 megapixel images, you’ll arrive with only one hair under 11 seconds.
The Eye-Fi Mobi is designed to be a card that works silently in the background. Yes, you can browse the card with a phone application such as Toshiba. But if you place the application on your computer, you can configure it to automatically download the files as they are triggered.
Use of energy
When you transfer files in real time, you can save a ton of battery in your camera. This is because the camera is already on to take the picture. It is already supplying voltage to the card, so that as long as the file is transferred successfully, the use will be negligible. You can still connect to the card while the camera is off, but it will consume power as long as it is connected. While restricting these sessions, you should not have any problems.
Eye-Fi Mobi Pro
The Mobi Pro is considered by many as one of the best wireless SD cards in the market. It has several key features that can not be found elsewhere, making it a great option for anyone who wants the best.
Surprisingly, Eye-Fi took a much more discreet approach to designing the Mobi Pro. Instead of the bright orange design for which they are famous, this card looks nothing more than a simple black SD card. But beneath its simple exterior there is a powerful hardware package.
The Mobi pro is available in sizes of 16 and 32 GB. Although it is a Class 10 card, the performance goes beyond what is required for the specification. It also has an updated processor and a wireless chip, which improves performance. But beyond that, the card is the same as the standard Mobi.
This card increases read and write speeds to more than 30Mbps, although this is adjusted dynamically depending on the type of file. The card is fast enough to record 4K video and can transfer a 3Mb file in less than 4 seconds. There is a bit of delay for transfer times, and there are many other things happening in the background. For this reason, your actual transfer times will be more or less the same as with the Mobi. If you are buying this card, you are buying it for additional functionality.
Like the original Mobi, the professional can upload files automatically to your computer. But it can handle many more file types, including RAW. Although it handles almost all modern market formats, you can specify your own file types in the included software. This means that you do not have to use it with a camera, as it will also work with documents, music and other media.
The main benefit of the card is the fact that it has access to the Mobi cloud. Instead of uploading all your files directly to the computer, they will be saved to your cloud account for free. With a quick login, you can access everything from a browser, so it does not have to be within the card’s scope for it to work.
Use of energy
The use of energy in the pro is the same as with the standard Mobi. But because you have the cloud, there is no reason to connect directly to the card. If you are recording video, you will have to wait for it to load. But the actual impact of the power in the camera is the same as if you left it on for 3 or 4 additional seconds after each shot.
