Managing 100 ucodes

ucoder (ucode Universal Information Service) associates ucode with information. This service is provided at the following URL: http://lab.ubin.jp/ucoder/ If you set up an account on this website, you can issue up to 100 ucodes. You can also set the association between those ucodes and the information on the Internet on the ucode resolution server. You can print the issued ucode in a tag in QR code format (ucodeQR) and attach it to an object and a place. If the attached ucodeQR is read by a mobile phone, the information set on the ucode resolution server can be retrieved on the mobile phone.

How to use ucoder

Step1: First, log in

By accessing the ucoder website,the screen as shown in Figure 1 will be displayed.

By clicking ”Create an account” at the bottom of the screen,License Agreement and e-mail address entry form will be displayed (Figure 2). Read the License Agreement carefully and agree to it, and then enter your e-mail address in the box and press CREATE ACCOUNT button. In a while, a password will be sent to your e-mail account from the ucoder server.

Step 2: Create a blog article

Next, create information to be associated with the issued ucode. Any information will do if it can be browsed on the website. However, in this example, as the information needs to be retrieved by reading the ucode by a mobile phone, the tool that supports mobile phones should be used. Accordingly, the goo blog is used. Create an article by using the goo blog and obtain the URL of the article. For the goo blog, the URL of the article is the link of the date and time of the posting (Figure 5). The URL of the created blog article is:

Step 3: Issue a ucode and associate it with information

Select ”Issue ucode” in the menu and the number of ucodes to be issued, then press Issue ucode button to issue ucodes. Now, let’s issue a ucode (Figure 6).

When a ucode is issued, the screen will be automatically switched to the “Register ucode” screen and the issued ucodes will be displayed on the list screen. On this screen, associate the ucode with information. Select “URL” on the right of the list, in the column of the resolution information and enter the URL of the blog in the text box below (Figure 7). Press UPDATE button to register the association between the ucode and information on the ucode resolution server.

Step 4: Create a ucode label

The ucode displayed on the ucode list screen is a link (blue letters in Figure 8).

By clicking this link, a new window (or a tab) will be opened and QR code screen will be displayed (Figure 9). Select the label size and press PRINT ucodeQR button to display a label on which ucodeQR is printed (Figure 10). Print and attach it to an object.


Here is an example of attaching a label to potted sansevieria (Figure 11).

Step 5: Retrieve information from a ucode

Let’s retrieve information from the ucodeQR of the created label. If the ucodeQR of the label is read by a mobile phone, the URL that includes the issued ucode will be displayed. By accessing this URL, the blog article registered at Step 2 will be displayed (Figure 12).

Now, let’s search on PC. Press ”Log-out” on the upper right of the ucoder screen to log out of ucoder. Enter ”01000047,” the eight digit figure written in the label in the search form of the top page (Figure 13) and press SEARCH button. A blog article in Figure 5 will be displayed.
