QR Code Scanning App (PWA)
Operation Manual

1. What is the QR Code Scanning App (PWA)?

This feature is available only to exhibitors who have applied for the QR Code Scanning App (PWA).

We provide an app for scanning the QR code displayed on admission passes. Instead of exchanging business cards with visitors, you can scan their registration information with a smartphone or tablet, enabling smoother collection of visitor data.

* Hereafter, this feature is referred to as the "PWA". PWA stands for "Progressive Web Apps," a mechanism/technology that allows websites to be used like apps.

2. System Requirements & Usage Flow

Minimum supported OS

• iOS 17.6.1 or later
• Android 14 or later

Devices confirmed to work

Basic usage flow

* QR codes are scanned one at a time. After each scan the app moves to the confirmation screen, where you can check the details before sending.

3. Installing the PWA (iPhone)

STEP 1. Display the installation QR code on the Exhibitor Only Site

Install the app on your device. Access the following URL on a PC and log in to the Exhibitor Only Site.

https://exb.jesa.or.jp/ceatec/admin/ex-mg-signon-pwa

Open STEP 1 of "PWA Installation to Login" and the "PWA Installation QR Code" is shown. Scan it with your smartphone's standard camera app.

STEP 2. Add to Home Screen

* This section shows the installation procedure on an iPhone as an example. For Android, see "4. Installation (Android)".
* Be careful not to open Safari in private (incognito) mode.

5. Logging In

After installing the PWA, log in so you can start scanning the QR codes on admission passes.

STEP 1. Launch the app and select a language

→

* Select your language at login. The language cannot be changed while logged in.

STEP 2. Register an identification name (device name)

Set an identification name for the device you are using. The identification name is output to the CSV log, so choose a name that is easy to identify. (It is also displayed in "PWA Login Device Information" on the Exhibitor Only Site, and can be changed after login.)

STEP 3. Scan the login QR code

The "Login QR Code" is shown in STEP 6 of the page open on your PC. Scan it with the camera in the app. (The camera launches automatically once you register the device name.)

* Do not confuse it with the "PWA Installation QR Code" in STEP 1.

If a dialog asking for camera permission appears, please allow it. When the scan succeeds, the TOP screen is displayed.

Using multiple licences (multiple devices)

The number of licences is the number of devices that can be logged in at the same time. With 3 licences, up to 3 devices can be used simultaneously.
There is only one login QR code per exhibitor. QR codes are not issued per device. Scan this same QR code on every device you use to log in.

The example below shows the same visitor being scanned on two devices.

FirstScan on the device at Reception A

Visitor QR code

▶

Device AName: Reception A

① Answer Q1 and Q2 (Q3 left blank) → send

▼　The same visitor then moves to Reception B

ThenScan the same visitor on the device at Reception B

Same visitor QR code

▶

Device BName: Reception B

② Q1 and Q2 shown with Reception A's answers already filled in

③ Fill in Q3 only and send → Q1 and Q2 stay as they are

Exhibitor
Only Site
(server)

Scan data and survey answers all arrive here when sent

Result:

• "Per visitor" CSV: one row (the identification name column contains the devices separated by commas — "Reception A,Reception B").
• "Cumulative" CSV: two rows, one for Reception A and one for Reception B.

In both formats the survey answer is the one sent last, from Reception B (Q1 and Q2 as entered at Reception A, Q3 at Reception B). (For the difference between the two formats and the output items, see "11. Downloading Logs (CSV)".)

How the system behaves with more than one device

The identification name is how you tell the devices apart later

The identification name you enter at login appears as-is on the Exhibitor Only Site and in the CSV. It is the only way to tell which device performed a scan.

→

※ Data is not delivered to the Exhibitor Only Site just by scanning. You must send it. Until then it exists only on that device.

※ The current number of logged-in devices is also shown on the "QR code system QR code for login" page of the Exhibitor Only Site.

※ When installing on several devices at the venue, the login QR code can be enlarged (see "12. Precautions").

※ On the TOP screen, "Total" is the figure for the whole exhibitor and "This device" counts only the device you are logged in on.

6. Scanning QR Codes

Once you have logged in, you can scan admission pass QR codes.

NEW Top of the screen: total scans (all / this device) and unique visitors.

Function 1: QR Code Reader

When you frame the QR code on the admission pass on screen, its content is read and the app automatically moves to the next screen. You can access each function from the navigation bar at the bottom of the screen.

Camera controls

Displaying and sending scan results

When a QR code is scanned successfully, the scan result screen is displayed. This screen displays personal information, so please handle it with great care.

→

Function 2: Scan History / Function 3: Send History

* Entries beyond the latest 500 are not displayed in the app, but all records are stored in the CSV file downloadable from the Exhibitor Only Site.

Answering or editing a survey afterwardsNEW

If you could not answer the survey at the moment of scanning, you can open the history later and answer or edit it. This lets you add your impressions of the visitor, or how promising the lead is, once you have finished serving them.

Only scans that satisfy both conditions — scanned with the PWA and successfully sent after scanning — are shown in the send history.
For use where reception is poor, see "8. Using the App When the Connection Is Unstable".

7. Answering the Visitor Survey

If you set up a visitor survey on the Exhibitor Only Site, it can be answered from the app. The responses are stored in the CSV file. Tap "Answer Survey" on the scan result screen to go to the survey screen.

→

Scanning the same visitor again

There is one set of survey responses per visitor. When you scan the visitor again, every question opens pre-filled with the previous answers. Questions you do not touch stay as they are; only the ones you change take a new value.

For the whole picture with two devices, see the diagram in "5. Logging In / Using multiple licences (multiple devices)". What is recorded is always the last set you sent, regardless of the CSV variant (per visitor / per scan).

8. Using the App When the Connection Is UnstableNEW

The PWA is designed to be used online. However, reception at the venue can be unstable, so the app lets you keep scanning even while there is no connection. Scanned data is held on the device and sent once the connection returns.

How you can tell the connection is down

When there is no connection, "● Offline" appears in the upper right of the screen. It disappears automatically once the connection returns. It is shown on every screen, not only on specific ones.

What you can and cannot do offline

* Logging in requires a connection. Be sure to log in somewhere with good reception before entering the venue.

Sending once the connection returns

You can send from either of the following.

* Once sent, the data appears in "Send History" (a connection is required to display it).

How much the device can hold

There is a limit to how much scanned data the device can hold. Once the limit is reached you cannot scan any more, so please send regularly.

* The limit depends on the app settings. You can check the totals (total / sent / unsent) under data management in "Other".

QR codes that cannot be read

If you scan a code that is not an admission pass, it is treated as an error on the spot, even with no connection. Codes scanned by mistake can be removed later with "Delete invalid barcode IDs only".

Managing the data held on the device

"Other" in the bottom menu contains "Data management", where you can check the totals and perform the following.

If you stay offline for a long time

If there is no connection for an extended period, you are logged out as a safety measure and will need to log in again. Move somewhere with good reception and log in once more.

* Unsent scanned data remains on the device after you log in again. Send it once you are back online.

9. Setting Up the Visitor Survey for the PWA

If you set up a survey on the Exhibitor Only Site, it can be answered from the app. Up to 10 questions can be added.

Setting items

10. Creating a Free-Text Field (also usable for notes after serving visitors)

The survey function can also be used by booth staff to record notes and supplementary information about visitors after scanning their admission passes with the PWA. You can add a "notes field (free-text field)" to the survey items.

• The question text can be anything you like. (e.g. "Staff notes", "Free-text field")
• For the answer format, we recommend selecting "multi-line text".

By adding a "staff entry field (notes about the visitor, etc.)", you can create a space to record the visitor's impressions, requests, conversation details, and so on.

11. Downloading Logs (CSV)

Booth Visitor Logs CSV data

When an admission pass QR code is scanned & sent at your booth, it is recorded as a CSV log. Generate it with the request button on the "Download Visit Logs" page.

Choosing the output format (per visitor / per scan)NEW

"Booth Visitor Logs" comes in two variants, "per visitor" and "per scan", and you can download both. They differ only in how repeat scans are split into rows.

<Booth Visitor Logs CSV data contents>
* Columns are identical for both.

• Barcode ID (unique number)
• Name (last / first / kana / English)
• Company/organization name / (kana) / (English)
• Department / (English) / job title / country
• Postcode / prefecture / city / address / building name
• E-mail / telephone number / gender / language
• Business / occupation / job position / purpose of visit / age group
• PWA last scan date-time / exhibitor name / identification name
• PWA visitor survey contents A, B, C… (questions and answers)

* Item specifications are subject to change due to ongoing development.

The identification name tells you which device performed the scan

The "identification name" in the CSV is the name registered on each device at login. When you use multiple licences (multiple devices), this column is the only way to tell which device scanned the visitor.

→

※ If you give the same identification name to several devices, they cannot be told apart in the CSV. Use a different name for each device (e.g. Reception A, Reception B).

12. Other Precautions

→

While it is within the validity period, the enlarged view can be displayed on another device by sharing the URL in the address bar. However, leaving a tablet or similar device displaying this QR code unattended at the venue greatly increases security risks — never do this under any circumstances.

13. Frequently Asked Questions (FAQ)

QDoes the QR Code Scanning App (PWA) usage fee include the cost of the device used?

The PWA is a rental of the app only; smartphones (tablets) must be provided by each company. Smartphone rentals are available for a fee.

QDo the smartphones (tablets) we provide need to be connected to the internet?

This feature uses an internet-capable smartphone to scan the QR code on the admission pass and save the scan results to a CSV file. It cannot be used on devices without an internet connection.
* We recommend using a mobile data connection (Wi-Fi is not recommended).

QCan one license be used on multiple devices?

Each license purchased allows use on one device. If you wish to use the app on multiple devices, please apply for the number of licenses you need.

QIf we purchase multiple licenses, can the delivered CSV data be separated per license?

Even if multiple licenses are purchased, the delivered CSV data will be one file per company.

QCan the survey be customized?

Yes. If you set up the visitor survey on the Exhibitor Only Site, it can be answered from the app. Enter and configure the necessary questions on the survey setting screen. Up to 10 questions can be added (see "9. Setting Up the Visitor Survey").
* When using the PWA in English, be sure to also set up English questions and choices.

QWhat happens to the log if the same admission pass QR code is scanned multiple times?

In the "per visitor" CSV the visitor occupies one row; in the "cumulative" CSV there is one row per scan (both can be downloaded). There is one set of survey responses per visitor, and scanning the visitor again opens the survey pre-filled (questions you do not touch stay as they are — see the diagram in "5. Logging In"). See "11. Downloading Logs (CSV)" for details.

QIs it possible to leave notes about visitors?

Yes — add a free-text (notes) field to the survey. See "10. Creating a Free-Text (Notes) Field" for details.
