Many people in Thailand encounter the term NDID when applying for financial services online but remain unclear on what it means, how it works, and how to register. This article provides a complete practical explanation covering every major bank including NDID Krungthai, NDID KBank (Kasikorn), and NDID GSB (ออมสิน).
What Is NDID — Clear Simple Explanation
NDID stands for National Digital ID — Thailand’s national digital identity verification platform, developed by NDID Co., Ltd. with the support and oversight of the Bank of Thailand. NDID allows Thai citizens to prove their identity through a digital channel using the biometric data their bank has already verified and stored — eliminating the need to visit a physical branch or resubmit identity documents every time they apply for a new service.
NDID vs National ID Card — Key Differences
| Feature | National ID Card | NDID |
| Format | Physical document | Digital, through a mobile app |
| How used | In-person at branch or office | From anywhere via mobile phone |
| Speed | Travel time plus queue waiting | Completed in 3 to 5 minutes |
| Technology | None | Blockchain plus Facial Recognition |
| Registration | Not required | One-time registration with your bank |
What NDID Can Be Used For
- Opening a bank account online with a different bank without visiting a branch
- Applying for credit cards, loans, and financial products through digital channels
- Opening securities and mutual fund accounts online
- Filing annual taxes through the Revenue Department website
- Completing transactions with participating government agencies
- Applying for life and health insurance online
How NDID Works — Phase by Phase
NDID operates in two phases. Phase one is registration, done only once. Phase two is identity verification, done each time you use NDID with a new service.
Phase 1 — Registration (One Time Only)
- Open the banking app for your account and log in
- Select the NDID service menu and tap Register
- Photograph your national ID card front and back
- Take a facial photograph facing the camera in good lighting
- Wait for system verification — typically 1 to 5 minutes
- Receive the confirmation notification when registration is complete
Phase 2 — Identity Verification (Each Use)
- Navigate to the website or app of the service you want to apply for
- Select the NDID verification option
- Choose the bank where you registered NDID
- Receive a push notification in your bank’s mobile app
- Open the app and approve by facial scan or confirmation tap
- Process completes — typically 2 to 5 minutes total

NDID Registration at All Major Thai Banks
| Bank | App | Main Requirement | Alternative Channel |
| Krungthai (KTB) | Krungthai NEXT | KTB account with KYC complete | Any Krungthai branch nationwide |
| Kasikorn (KBank) | K PLUS | KBank account activated | Any KBank branch nationwide |

Registration must be done with a bank where you already hold an account — you cannot register NDID with a bank you have no account with. If you hold accounts at multiple banks, you can register NDID with each separately and choose any of them when verifying identity.
NDID Security — How Your Data Is Protected
- Biometric data (facial) is stored by your bank — it is not sent to external service providers
- When a service provider requests verification, your bank answers only yes or no — no actual biometric data is transmitted
- Blockchain technology prevents data tampering during transmission
- Every verification requires your explicit approval through your bank’s mobile app
- If you receive an NDID notification you did not initiate, reject it immediately and contact your bank
