Low carbon, environmental friendly and intelligent - Elfinbook can repeatedly write notebook trial report

Thank Lei Feng Love to play computer games Trial play and Hangzhou Qihui Technology Co., Ltd. enabled me to obtain the trial qualification of Elfinbook rewritable notebook.

1、 Appearance

Elfinbook is a notebook that can be written repeatedly. The paper is made of stone paper, which is not only waterproof, but also durable. If it is used with the APP, the written notes can also be saved through the APP client, and images can also be processed. Let's have a look.

The outer package of Elfinbook is a white box. The front is pasted with the activity label of playing computer games.

The back is very simple. There is only one QR code in the center. Scan the code to download the matching APP. The following is the design manufacturer and company address.

There are three mobile phone pictures printed on the front of the box, which are the three main functions of the APP: automatic content scanning, image distortion correction, and effect enhancement.

The following are the main features of Elfinbook:

  It is made of stone, smooth writing, waterproof and durable, reusable, automatic scanning, handwriting enhancement, cloud backup, and document management.

There is a matching ink pen, a manual and a VIP card in the package.

The manual details that there are two erasing methods for the matched Baile erasable pen, 1 is Support water-soluble color pen Wipe with wet cloth, and 2 is heat wipe. There are also some precautions and functional features.

There is a vip exchange code on the front of the Vip card, which can be upgraded to advanced users by scraping it open and entering it into the APP, and all the functions of the APP can be used for free.

On the back is a letter of thanks for your trust and support.

Baile pen is similar to an ordinary carbon pen. It has a plastic shell. The difference is that there is a flexible rubber at the end of the pen.

The rubber can be rubbed to erase the handwriting written by the pen. Because ink can be erased, the pen clearly reminds that it is prohibited to use it on important documents such as signatures and securities.

The back of the notebook is as simple as the back of the box, with only the QR code of APP printed on it.

The notebook paper is cut neatly, the opening of the skin is accurate without burrs, and the paper is sealed by inserting iron wires.

Write test on notebook.

Please ignore my font. The font is very ugly.

The paper is smooth and thin, the pen feels good and the ink is smooth. Just because the paper is too thin, the back of the paper will leave an impression of handwriting after writing.

2、 APP use

After scanning the code, you can download the APP.

Before the APP is used, there are tutorials with pictures and texts.

The document area and search bar are directly above the main interface. In the document area, you can click the+sign to create a new folder.

In the middle is the saved picture. The three horizontal lines in the upper left corner pop up the menu on the left. The management in the upper right corner can access the interface of all saved pictures for detailed management.

Click the three horizontal tabs to open the menu for login and registration. You can also upgrade to advanced users to unlock all functions.

Click the photo button below to take photos.

When taking photos, the software will use machine vision and image processing algorithms, and will automatically find the frame of the notebook for trimming and straightening.  

Of course, the edge position can also be adjusted manually. If you are not satisfied with the automatic positioning of the software, you can also drag the circle with your finger to fine tune it.

After clicking the check mark, you can save the photo in the APP, and it will automatically stretch and correct it to become a square picture. You can also select a variety of image enhancement effects, including black and white, color, and enhancement modes. This is similar to the filter of an image, which can be adjusted according to your own preferences.

After saving, the picture will appear in the document.

Click PDF Preview to generate PDF.

Because the trial version has watermark, if you want to remove it, you need to upgrade to the VIP version. The monthly use fee of Vip version is 6 yuan, including 49 yuan per year. It's more economical to buy a year. All functions can also be unlocked.

PDF files can also be shared in many ways.

Test a document with a larger tilt angle.

The software can still locate the edges and corners automatically.

After automatic correction of stretching, the effect is very good.

The icon in the lower right corner of the main interface can add photos saved in the phone to the APP for modification and editing.

3、 Erase test.

The reason why the pen can be erased is that the ink is water-soluble, so it can be dissolved in water. When you scrub it with a wet cloth, the ink will dissolve, fade and disappear. In addition, ink supports thermal erasure. When the rubber at the end of the pen rubs against the paper, it will generate heat. Heat will render the ink color ineffective. Therefore, it can also be erased with rubber.

Let's test the rubber wipe first.

It's easy to erase the words after a few strokes.

The book is made of stone paper and can be reused for as many as 10 times with erasable pen. After erasing, there is basically no trace left on the paper.

In order to verify the effect of the ink disappearing after being heated, let's take a test.

Boiled a cup of boiling water, and when the cup with boiling water is placed above the handwriting, the handwriting disappears instantly.

  It's like magic.

It's amazing that the handwriting disappeared without trace.

4、 Summary

Elfinbook's paper is made of stone, which is strong and durable. It can be repeatedly written and erased for more than 10 times with a special Baile pen, saving trees, low carbon and environmental protection.

Elfinbook's supporting APP has a powerful document management function, which can perform classification management and search at the same time. The saved image materials can be easily made into pdf and uploaded to the cloud, such as impression notes, Baidu Cloud, etc., which eliminates the damage and loss of paper documents.

The APP will automatically scan the edge when taking photos, and automatically identify the frame of the target object. After scanning, the distortion becomes positive. With the application of image processing technology, a variety of filter effects can be selected. The background of the picture is whitened, and the content is color enhanced, so that the display effect is close to the naked eye.

In the era of promoting low-carbon and environmental protection, Elfinbook rewritable notebooks are very suitable for daily office work and diary of our office workers, and truly achieve low-carbon zero emissions, environmental protection and intelligence. Therefore, I encourage everyone to buy and use Elfinbook rewritable notebooks, do a little for our environment and make a little contribution to the cause of environmental protection.
