Another case is when you are on a business trip and the need to send the documents you have just received in paper emerges.
These different cases and tasks have something in common. Guess what? That’s right - a portable scanner is the right thing to solve both!

Well, technically the device in question is called an image scanner, but very often the ‘image’ part is dropped, so we get the usual commonly used name of ‘scanner’. Scanners’ origins are found in telegraph-based devices, such as pantelegraph. The pendulums on different devices were synchronized with the help of electromagnets, which helped reproduce images and send them as if it was a facsimile machine.
The next stage of development was represented by Belinograph, which appeared in 1913. It was capable of transmitting photos over phone lines. It was in use up to the mid-1990s. Modern scanners of various types appeared in the 1950s, when drum scanners were invented. Later types of scanners, such as CCD and CIS scanners, were constantly enhancing in terms of resolution and other parameters that affect the quality of the scanned image.
Portable scanners are hand-held or compact devices that are designed to scan documents for further use of these digital images. Such scanners are distinguished by high portability and thus can be taken even to the North Pole.
Portable scanners may come in handy in a variety of cases and are preferred by many people due to their indispensable quality, that is portability.
- Office workers and businessmen. There are plenty of reasons why those dealing with lots of documents can fancy such a device. Imagine how convenient it may be to have a portable scanner while on a business trip! Cafes, hotels and other places you may face the need to scan documents are no longer a challenge, as you always have a portable scanner in your case;
- Owners of small apartments. Why should you buy a desktop scanner if you scan once a year (to make sure the verses your aunt has written to congratulate you on your birthday will never perish)? Portable scanners take way less space than desktop versions. No dust gathering is a bonus;
- Families on vacation. You are enjoying a picnic in the mountains where you have gone on vacation, and your child has drawn the sunset you are looking at. The drawing will likely tear or get wet. Don’t fret! Just scan it with a portable scanner and here you go! If you have a notebook or a laptop with you, you can also share such moments with other people;
- Salespeople, insurance adjusters, etc. Some professions require a lot of skills in managing documents, and doing it fast. It is when portable scanners can save your day - and no bill will ever get lost! Students and researchers definitely need portable scanners too.
Desktop scanners dominate the market, but portable versions are doing their best to gain ascendancy. And it’s no wonder, since easy-to-carry scanners have a lot to offer:
- High portability. Use it anywhere you like and need it. No matter where you are, you will always have a way to scan and send the documents you handle;
- Good quality.Though portable scanners are small in size (as they are intended to be so), they provide good quality of scanning. Such an advantage makes a portable scanner a decent substitute for a desktop device. A good portable scanner can be compared to its big brother in many respects. Here in an important note: good quality is achieved only if you operate the device accurately while scanning.
- Lower price. In most cases portable versions cost less than full-sized ones, and in the scanner world the rules are the same. Crucial features and good quality are combined with affordability;
- Various designs. Portable scanners look stylish. Their elegance can be manifested in many different designs. There are even long cases that glow and remind of a laser sword, or a lightsaber. Buy a portable scanner and feel like a Star Wars warrior!
- Convenience. Due to their small size, portable scanners are easy to store and handle. They can be carried in a backpack, case or almost any bag, which means you will never be caught unawares when the need for scanning arises;
- Cloud technology. All images you get as a result are stored in the cloud or on a build-in drive, which means you can download them later to your computer or send straightaway.
The drawbacks of portable scanners are somewhat related to their advantages and stem from them.
- No feeding feature. The biggest concern of portable scanner owners is that it cannot feed the paper, which means you will be involved in the process every second. It is quite all right if you need to scan a couple of documents occasionally, but if you encounter piles of papers that need to be scanned on an hourly basis, it may be a crucial inconvenience;
- Size limitations. Due to their small sizes, portable scanners are capable of working with relatively small paper sizes. It is by no means a problem if all you scan is bills, but when it comes to scanning some plans… well, it’s going to be a challenge!
- Power supply. Most portable scanners can drain power either from your laptop or using special batteries. In each case you are to be prepared for a sudden turn-off. To avoid such disappointment, carry power banks with you or charge your laptop beforehand;
- Slow operation and quality limitations. As everything is carried out manually, the operation is quite slow. It will take more time to scan all the documents you need, so get ready for routine. Also, most portable scanners are good for scanning documents, but when it comes to photos, they certainly fall behind the desktop versions;
- OCR function may not be present. OCR has become an important part of scanning documents, since it allows further work with the text written on these papers. Some portable scanners do not feature such a function, so keep an eye on what you choose.
There is a great variety of portable scanners presented in the market. All of them differ in the number of features, power supply type, size of paper whey can process, etc. Let’s try to figure out what is special about each type. Note that we are not going to consider, say, flatbed scanners, as they are not portable (or at least easily portable).
- By resolution. Resolution is a parameter indicating how detailed the image will be. It is measured in DPI (dots per inch). Normally 300 dpi are enough for text documents, but if you need to scan photos or other papers that require high resolution, at least 600 dpi are a must. Of course, highest resolution portable scanners cost more than those providing low resolution;
By power supply. As to power supply, mobile scanners fall into two groups:
- USB portable scanners. They are connected directly to a laptop or computer and drain power from them;
- Battery-powered portable scanners. Such scanners do not necessarily need a power source as the ones above do. This type is sometimes called self-powered portable scanners;
- By size. Size matters when you are always on the road. Models may differ in size dramatically (even within the range of portable scanners). There are compact versions that are quite lightweight but still remind of desktop scanners and ultra portable scanners that can be carried in a pocket. Each type is designed for specific needs;
- By design. Minimalistic, futuristic, glamourous, jet-black… There are plenty of designs that attract attention, but keep in mind that sophisticated design always affects the price;
- By features. While most scanners lack feeders, there are models which combine portability and this useful feature (for instance, Canon P-215II is equipped with a 20-sheet automatic feeder). Another feature worth mentioning is whether a scanner is capable of optical character recognition (OCR). If it is not, though, there are still third-party apps and software that can do the job for it. Some scanners are so clever they know how to scan both sides of a document at once! There are also scanners that can connect to the Wi-Fi network and send the data without any cords.
- By speed. Most modern portable scanners have a speed of 5-8 pages per minute. It is a very good result, but mind that in case of wand-type scanners it is you who is responsible for the image quality and accuracy. In case of duplex scanning speed is also slowed;
- By operation. There are two ways of operating portable scanners: either they are handheld (and in such a case you are to move it a lot) or they are just compact but still remain placed on some surface and do not require much involvement. This parameter is closely connected to the size. Small pocket scanners need your constant assistance.
When choosing a portable scanner, stick to the following rules.
- Consider the price. Once you set the budget for such a purchase, you can take a look at what you can afford within the determined range;
- Think of what you are going to scan. If the only kind of papers you need to have digital copies of is text documents, models with low resolution (300 dpi) would fit best. If colour photos are your priority, consider buying a 600 or 1200 dpi color scanner. Photo scanners are commonly more expensive;
- Estimate how often you are going to scan. Scared of document piles looking like the Leaning Tower of Pisa? Imagine how tedious would it be to scan all of them! Before buying a portable scanner, try to estimate how often you may need to use it. It is one of the crucial points of choosing a scanner.
- Mind the frequency of moving. Your choice should depend on whether you need a portable scanner just to save space at home or your office, or you are working in the field of sales, insurance, etc., which means you are always on the go. The first ones may aim at compact models; the others are likely to enjoy handheld portable scanners;
- Keep an eye on the features. Such features as OCR are also dependable on your daily needs. If you plan to find certain words in the documents later, do not forget to check whether the model you like features OCR. File format in which digital copies are made can also matter, as JPEG files cannot contain text like PDF does;
- Check whether it is compatible with your OS. Some scanner drivers work only with Windows OS, so if you are a Mac owner, make sure to check whether it is compatible with all your devices. Some scanner drivers require monthly subscription, so be careful when choosing!
Since there are plenty of scanners to choose from, it is rather difficult to make a list of the best. Nevertheless, we have made an attempt to compile a list of portable scanners you may enjoy using most.

‘Since I use it all the time and even though it is only one page at a time, it has been a life saver! It travels well, is powered by just the USB (no plug in power). I have dropped it and it still works fine’ - Zen
‘I use a flat bed scanner at the office but, since I have started traveling much more, I wanted a portable solution to scanning receipts while on the road. This one got some good reviews and I liked the form factor. It will scan full 8.5x11 documents (common at hotels) as well as the small register tapes (restaurants, etc...). It's fairly quick, the images are perfect for submitting to my client, and it fits in my computer bag right next to my 17" laptop. The fact that it's powered directly through the USB cable is perfect - no extra AC adapter to carry. The applications that come with it are great, too’ - David J. Thompson
‘This product is tricky, but once you make some software adjustments it will work just fine for you’ - C. Houlroyd

‘It's easy to use; you just press the pointer to the page and a light comes on to let you know that the sensor is active... The recognition rate is higher than I thought it would be; it's better than 99% on book-sized text... The character recognition is sometimes thrown off by underlining and other marks on the page... Even though it recognizes just about every major language written in Latin, Cyrillic, or Greek letters, it can't handle older typefaces (like German Fraktur)’ - T. Bryan
‘Not only does it create legible conversion (over 90%) but once you lift the pen it creates a space for you..(no need to hit a button on pen) This is probably the only one that should be invested in…’ - M.T.S.
‘It works great! Only one thing wrong--the cord needs to be longer so you can reach whatever you are scanning!!’ - Patricia Bruton
3. Doxie One
This is a portable photo and document scanner, which is perfect for scanning documents since it is characterized by 300 dpi resolution.

‘Overall a neat little device. I am finding myself scanning everything now because it is so convenient. The only thing that would make this a five star product to me is the ability to scan directly from the device to my computer when connected via USB, but really the portability makes up for that limitation’ - Edward Wilson
‘This is one of the best purchases I've made in awhile! It has been difficult to find a picture scanner I could use with my Mac but not only did this work, it worked without having to download and fill space on my Mac!! And the pics are great!’ - Lisa Sitze
‘Pretty good scanner. I had an issue using batteries. Apparently I had tried the wrong kind of batteries and had some issues. I expressed that in a previous review. Doxie immediately contacted me and helped me to work through the issue. This is truly what customer service should be in this day and age and I am really impressed. I travel with the scanner and it is easy to use. It is great for archiving’ - Andrew VanDewater

‘While this little scanner is no substitute for a high-quality flatbed with all sorts of useful tweaks available, when your goal is to import as many photos as fast as possible, this works great’ - SirWired
‘Very easy setup. I like the fact that the right edge guide adjusts to any document letter size or less. Included PaperPort software from Nuance works real well. I especially like how you can create multipage PDF documents. I made the mistake of getting the BR-Receipts software which costs an additional $9.00. Bad mistake. The software is worthless’ - H. Pritchard
‘It's easy to use although when I first tried scanning my receipts for the business I didn't notice that apparently the default file path was to jpeg so I had to change that. Also, when scanning the first few receipts they came out unreadable until I changed the resolution from the main setup page. After doing those two things I haven't had any trouble. Another plus is I can rename some of the buttons to suit my purpose such as office expenses, supplies, car expenses, etc.’ - Judy K. Jensen
This is a compact portable document scanner that has an ADF, which is certainly a bonus for those who deal with lots of documents at a time.

‘The Canon software is intuitive and customizable and I really like it. However, the software for document management isn't very good’ - Ed
‘Paper feed is still hit or miss. I expected as with other document feed scanners that you push the paper until it hits the stop and you should be done with it. This machine requires that once you hit the stop you have to push it in a bit more or it won't pull it in. Feeding a stack of paper also doesn't work very well unless you add each piece individually on top of the first. I've tried as many ways as I can conjure up to feed multiple sheets but this seems to work the best’ - B. Langevin
‘The scanner is great. The software could be a little bit better’ - Kelly Speer
If you have no opportunity to buy a portable scanner, there is a good substitute for it, and it is closer than you think. Modern smartphones have decent cameras, and when combined with special apps that turn photos into scans, it works quite well. Of course, in such cases much depends on the quality of your camera, so it cannot be considered a full-scale substitute. You might be interested in apps like CamScanner, Tiny Scanner, Office Lens, etc.
All in all, portable scanners are great if you need to scans documents, bills, receipts or something else often. Such scanners require less space than desktop ones and still can provide good efficiency, though many of them lack ADF. Whether you are a salesman or a student (or someone else who needs to scan papers on the go), consider buying a portable scanner.
P.S. As a bonus, less paper documents means less damage to forests.
