tk4 A Few Steps to Your tk4 Account
LOCAL DEPOSIT METHODS

Paying In via bKash, Nagad or Rocket

After your account is created, adding a deposit method takes under a minute. Open your bKash, Nagad or Rocket app, send to the account number shown on the deposit screen, and confirm with your PIN. The transaction reference appears in your wallet once the transfer is picked up. Rocket works through Dutch-Bangla Mobile Banking the same way — send from the app, confirm the reference. All three methods are listed in the deposit tab on the account dashboard.

bKash Send from the bKash app to the number shown on the deposit screen. Confirm your PIN and the reference appears in your tk4 wallet once received.
Nagad Open Nagad, enter the account number from the deposit tab, confirm with your PIN. Your wallet balance updates once the Nagad transfer is picked up.
Rocket Use Dutch-Bangla Mobile Banking through the Rocket app. The deposit flow matches bKash — send, confirm PIN, check the reference in your account wallet.
ACCOUNT HELP PATHS

Getting Help With Your Registration

Registration issues are usually mobile number conflicts, OTP delays or form validation errors. Each of these has a clear fix, and our support team can walk you through it from inside the Help section. Availability varies, so check the Help tab for current response windows before you wait.

Live Chat Open the chat widget from the Help section while you're on the registration page. The agent can check your account status and unblock verification steps in real time.
Email Support Send your registered mobile number and a description of the issue to the support email listed in the Help section. Responses include account status and next steps.
In-App Help Centre The Help Centre inside your account covers OTP issues, payment linking and identity check steps with written answers you can follow at your own pace.

How the Sign-Up Flow Works

When you open the registration form, you'll enter your mobile number, set a password and confirm with a one-time PIN sent to that number. After the OTP clears, your account is active and your wallet is visible on the account dashboard. From there you can add a deposit method — bKash, Nagad or Rocket —

directly from the payment tab. Identity checks may be required before your first withdrawal; having a clear copy of your ID ready speeds that step up. If anything stalls during registration, our account support channel is reachable through the Help section inside the site. The whole path is designed to work on a phone browser

without needing an app install first.

  • OTP Verification Your mobile number is confirmed with a one-time PIN before the account activates. This keeps your account tied to a number only you control.
  • Wallet Ready on Login Once registered, your account wallet is visible immediately. Link bKash, Nagad or Rocket from the payment tab to move funds in or out.
  • Identity Check for Withdrawals A document check is required before your first withdrawal is processed. Preparing a valid ID in advance keeps that step straightforward and quick.
  • Account Help Inside the Site If your registration hits an error, head to the Help section. Our support team can verify your account status and unblock any step that stalls.

ACCOUNT SAFETY SIGNALS

How We Protect Your Account

Your account details and payment data are handled under SSL encryption, meaning the connection between your phone and our servers is private end-to-end. OTP login means no one can access your account without the PIN sent to your registered number. We do not store bKash, Nagad or Rocket PINs on our side — those stay inside your wallet app. Data handling follows the terms published on this site, and you can request account data or closure through the Help section.

SSL Encryption Every page on tk4 runs over SSL. Your registration details, login sessions and payment references are encrypted in transit from your device to our servers.
OTP Login Control Your mobile number acts as the second factor for account access. Login attempts from unrecognised sessions trigger a fresh OTP to your registered number.
Identity Verification Document checks before withdrawal protect your wallet from unauthorised access. The verification step is a security layer, not just a compliance formality.
Data and Account Control You can request your account data or ask for account closure through the Help section. We do not sell personal data to third parties outside of what our terms describe.

Common Questions About Creating an Account

These are the questions we see most often from people going through the registration flow on tk4. If something is not covered here, the Help section inside the site has more detail.

You need a working mobile number in Bangladesh and a password you set during registration. An OTP is sent to that number to confirm the account before it goes active.

Yes. The registration form works in a mobile browser. You do not need to install anything first — open tk4, tap register and fill in the form directly.

bKash, Nagad and Rocket are the main deposit options available. After your account is active, open the payment tab on your dashboard to link whichever method you use.

Wait a moment, then use the resend option on the OTP screen. If the number still does not receive the PIN, contact support via live chat with your mobile number ready.

Not immediately. Identity verification is required before your first withdrawal is processed. You can deposit and explore the lobby before the document check is triggered.

Access to tk4 depends on local law and the eligible regions we currently support. Registration is open where the platform is accessible; check availability in your area before proceeding.
