Rules for bKash, Nagad, and Rocket

All BDT accounts separate

During transactions, if name and number match, processing is faster; using bKash, Nagad, and Rocket is most convenient for Bangladeshi users.

If any information is incomplete, verification stops; therefore keep the phone number, account name, and Dhaka location information consistent.

bKash Verification

If the number and name are correct, the process is faster; if incorrect, support may request verification.

Nagad Verification

Entries made with Nagad are usually processed quickly, but if the information doesn't match, you may have to resend.

Rocket Verification

Using the same name for Rocket account makes it easier; it reduces confirmation steps.

a4 Login Security and Source Verification

During a4 Login, check password, device, and network; if logging in from an unknown device, the system may require extra verification.

If using a shared phone, end the session; especially when using cafe or office WiFi, stay vigilant.

If multiple accounts, fake information, or suspicious activity are detected, it may be temporarily suspended; a warning comes first, then restrictions may be applied if needed.

This section is strict, but following clear rules reduces the need to explain later.
