Set up your All-in-One Wallet
To use the All-in-One Wallet on iOS, your iPhone must support NFC. NFC is available on iPhone 7 and newer models, and your device must be running iOS 13 or higher.
Enable NFC on your phone
On iPhone, NFC is enabled by default. On Android, turn NFC on and set it to "Read/write NFC tags".

Mobile App basic setting
Select Wallet mode
When you launch the mobile app for the first time, follow the initial setup and choose a wallet mode.
This guide is based on D’CENT mobile app version 8.0.0.
On the wallet selection screen, choose "Card Wallet" as shown below.
App Password Registration
To protect the D'CENT mobile app, set a 6-digit app password. You will need to enter this password every time you open the app, so make sure to remember it.
If you forget the 6-digit password, you will have to reinstall the D'CENT app.
You can change the app password later from the app Settings menu. For extra security, you can also enable biometric (fingerprint) login.
Mobile App Permission Settings
When you launch the D'CENT mobile app, a permission request popup appears. Review the requested permissions, then tap "Confirm" to continue.
Set up the All-in-One Wallet
Scan your All-in-One Wallet
1) Hold the All-in-One Wallet against the back of your phone to scan it.
2) Tap "Allow" to grant notification permission. You can turn notifications On or Off at any time from the Settings menu.
For details about the notification feature, see this guide.
The NFC antenna is located in a different spot on every phone model. If the card is not detected, slowly move it across the back of your phone to find the antenna.
A thick phone case may interfere with the scan. If recognition fails, remove the case and try again.
3) Once the All-in-One Wallet is recognized, wallet synchronization begins automatically.
4) When the sync finishes, the My Wallet tab shows three default accounts: Ethereum, Kaia, and Polygon. To add more coin or token accounts, tap "+ Add Account".
Change the factory PIN to your own PIN
The first time you scan the All-in-One Wallet, a banner appears asking you to change the factory PIN.
Before you can use the wallet, you must replace the factory PIN with your own PIN.
1) Tap the banner at the top of the screen to start the PIN change.
2) Tap "Change now".
3) Check "I have checked the information", then tap "Start".
4) Reveal the factory PIN by gently scratching off the ribbon masking on your All-in-One Wallet.
Use your fingernail or a blunt tool to remove the ribbon masking. Do not use sharp objects—they may damage the card.
5) Enter the 6-digit factory PIN (for example: 530226).
6) Hold the All-in-One Wallet against the back of your phone to scan it.
7) Enter a new 6-digit PIN for your All-in-One Wallet (for example: 123456).
8) Re-enter the same new PIN to confirm it.
9) Hold the All-in-One Wallet against the back of your phone to scan it again.
10) Tap "Confirm" to finish changing the PIN.
The card PIN of the All-in-One Wallet is different from the 6-digit app password used in the D'CENT mobile app. Mixing them up can lock you out of your wallet, so be sure to remember each one separately.
