Convenient Memo with IT

Jeong Yak-yong, also known as ‘Dasan’ and one of the greatest thinkers, once said, “A dull writing brush can defeat the intelligence”. It means, if you study hard you will be able the achieve success. Memos can overwhelm memories and it helps to organize the thoughts. Especially, these days, where massive information is dealt, it is important to write down memos effectively.

Most people have written down memos on a piece of paper. Unfortunately, it had some difficulties of recording when you don’t have a piece of paper and disadvantages of losing the memos. However, these inconvenient features are improving by IT.

Recorded memos on papers can be digitalized and it makes possible to take down memos effectively. Let’s take a look at some technologies and helpful services related to memos.


① Memo with Cloud

Cloud lets the software and data to be stored in the central computer which is connected with the Internet. This means, users are possible to work with various electrical devices, anytime, in any places, by connecting to the Internet. For example, it is possible to start the work at home with your laptop and finish outside with your smartphone.


Nowadays, most memo services use Cloud which lets to take down memos in any kinds of electrical devices and lessens the possibilities of losing the saved data. Evernote is one of the leading services that uses Cloud.

The best feature of Evernote is the high compatibility. Not only in web browser but in mobile OS (Android, iOS, Windows Phone), Evernote is possible to use. Moreover, with the auto sync process, it allows to take down and view memos in anytime with various devices such as laptop and smartphones, etc.

Apparently, people can now easily take down memos without any restrictions of places and devices. Thanks to Cloud.

② Memo with nCode technology

When the tiny dots of nCode writes down on various kinds of surfaces, the sensor installed in the pen recognizes the writing information and digitalizes it. This technology was first created by a venture business called ‘NeoLAB Convergence’.

Let’s compare the Bar Code, QR Code, and nCode. The large sized Bar Code and QR Code is easy to be seen, but the tiny dots of nCode is almost invisible. Therefore, even when the image is filled with nCode, it is hard to see the code and creates a sound quality of the image.

nCode has its own code value, which means the content has a coordinate information. When a pen touches the surface of a content, filled with nCode, a special sensor inside the pen recognizes the coordinate value and brings the information that is matched.

nCode technology is used in a memo device, the smart pen. Neo Smart Pen N2, from ‘NeoLAB Convergence’, is a memo device using the nCode technology. It is also known as a pen with balanced analogue and digital features.

When you write with the Neo Smart Pen N2 on a piece of printed paper, with nCode inserted, memo data is digitalized. Even when the memo is created in analogue style, it is recorded in electrical devices. Pen leads are possible to be replaced by the D1 type leads (standard type) which can be easily purchased.

Also, the Neo Smart Pen has a language setting function that allows to recognize the chosen language, and 15 different languages, including Korean and English, are mounted. However, two different languages are not able to be recognized simultaneously.

By using this function, written memos in selected language are converted into texts that can be modified. In other words, written memos can be modified through electrical devices and this would be very useful in a situation when changes have to be made quickly.

nCode technology is also used in contents for children. When the pen touches a book where nCode is inserted, the pen recognizes the code information. For example, when the pen touches an image of a puppy in book, a barking sound will appear from the pen.

③ Memo with NFC 

NFC (Near Field Communication) is a technology that enables data exchange between two devices within 10cm by using frequency. Not like the electronic tag, it has two-way sending function and does not have a complicated connecting process.

NFC is used in various ways, for example, in online payment and searching for concert information, etc. Then, how is it used in memos? When memo data needs a backup, it is done by just facing the smartphones back to back while the NFC function is on.

With LG G5 Qmemo, backing up data is available through NFC backup function and it allows to take down memos without turning on the smartphone. While on a screen of time and alarm, by pressing the volume up button twice, Qmemo appears and lets you write down memos in a second.

Without connecting two smartphones, LG backup system stores the Qmemo data by using the NFC backup function. Also, photos, apps, and app data are possible to backup by the NFC tagging.

By using this function, it is easy to backup data between two smartphones without having model restrictions, and also it allows to store various data (memos and pictures, etc.) more effectively.

④ Document scanning with smartphone camera 

As memo combines with technology, papers and pens are not necessarily needed to record data. Moreover, CamScanner makes possible to scan and save paper documents without using additional devices.

CamScanner is an app for Android and iOS. By taking a picture and selecting the area of the document, a scanned version of the document is created in PDF or JPG file. Also, it can be modified afterwards and share through the app. An upgrade version of the app has a fax function as well.

Scanning devices are not necessarily needed these days, and with CamScanner service, various sizes and forms of paper documents are able to be stored.


Memo technologies and services will be able to help people in numerous ways. People would be able to work effectively, save time, and increase the productivity.


Seoktae Kang of LG CNS, one of the core members of inventing the Talk ordering service, has a habit of taking down memos when new ideas pop up. This habit eventually led to saving more than 450 unique ideas.

Taking down memos is not a hard thing, but making this into a habit is something you need to put an effort. Fortunately, many services that help to take down memos are being invented nowadays, and hope people could upgrade their lives with these services.
