EVERYTHING AUTOMATED

One click on START — the engine handles every step of the IVAC flow.

🔐

Auto login + OTP

Signs in with your number & password, and the OTP from your phone's SMS is filled in and submitted automatically by the OTP Reader app.

📄

Auto file upload

Uploads Primary + up to 3 co-applicant PDFs one by one, verifies each against the site, and never marks a file uploaded unless the server confirmed it.

🎯

Mission & centre

Picks your mission and IVAC centre from the config and verifies them on the real page.

📅

Smart date scan

Cycles dates with your chosen gap, forward or backward, and keeps retrying until a slot opens.

🔔

Slot alert

Instant sound + on-screen alert the moment a bookable slot or the payment page appears.

🧾

Document identity check

Reads each PDF and shows name, passport, visa type and application ID — so the wrong file never gets uploaded.

HOW IT WORKS

From payment to a working key — usually under a few minutes.

01

Order & pay

Choose your devices and place the order — your order page then shows the bKash/Nagad number and the exact amount.

02

Download & get your ID

Your order page unlocks the package (extension + APK) and the setup video. Install it, then copy your Machine ID from the extension.

03

Paste the ID → key

Paste the Machine ID on your order page. The signed key appears instantly — put it in CONFIG → License → ACTIVATE and press START.

SETUP VIDEO GUIDE

Watch once and you can set the whole thing up alone.

FREQUENTLY ASKED

Where do I find my Machine ID? +
Install the extension → open the panel → CONFIG tab → License section → press the 📋 copy button. That ID belongs to that one computer.
Can I use one key on two computers? +
No — for two computers you need 2 devices in your order (৳5,000 + ৳3,000). A single-device key shows WRONG MACHINE on any other computer. This is exactly why a key cannot be shared or resold.
Where do I send the money? +
Place your order first — the page then shows the bKash/Nagad number and the exact amount for your device count. Always check the amount on that page before sending.
How does the OTP work? +
Install the OTP Reader APK on the phone that receives IVAC SMS. It reads the OTP and sends it to your extension automatically — you don't type anything.
How long does approval take? +
Usually a few minutes. Keep the order page open — the key appears by itself as soon as the payment is verified.
What happens when the month ends? +
The key stops working and the engine stops too. Buy a new month and paste the fresh key — nothing else to reinstall.
Does the site update break it? +
We follow IVAC changes and ship updated builds to active customers. New builds are announced in the Telegram group.
