The Bitunix Card allows you to spend your USDT just like a regular Visa card. Behind the scenes, your crypto is securely converted and settled through the Visa payment network in real time.
Here's how a typical transaction works:
Step 1: Deposit USDT into Your Bitunix Card Account
Deposit USDT into your Bitunix account then transfer USDT from your Spot/Futures account into your Bitunix Card Account
This balance will be used as the funding source for your Bitunix Card.
Step 2: Make a Purchase
Use your Bitunix Card anywhere Visa is accepted, whether online, in-store, or through supported digital wallets.
When you tap, swipe, or enter your card details, the merchant sends an authorization request through the Visa network.
Step 3: Authorization Check
Before approving the payment, Bitunix verifies that:
- Your card is active and not blocked.
- Your available balance is sufficient to cover the purchase.
- The transaction passes security and risk checks.
- The merchant category is supported.
If all checks pass, the transaction is authorized within seconds.
Step 4: USDT is Used to Fund the Purchase
Once the transaction is approved, the required amount of your USDT is used to fund the payment.
If the purchase is made in a different currency (such as EUR, JPY, or GBP), the payment is converted using the Visa exchange rate, together with Bitunix's applicable FX markup, before calculating the required USDT amount.
The corresponding USDT is deducted from your available balance.
Step 5: Visa Pays the Merchant
Although your spending is funded with USDT, the merchant receives payment in their local fiat currency through the Visa payment network.
From the merchant's perspective, it works exactly like any other Visa card payment.
Step 6: Transaction Settlement
Most card payments are first authorized and then settled by the merchant.
Settlement usually occurs within 1–3 business days. Once settlement is completed:
- Your transaction status is updated.
- Any applicable cashback is calculated according to your current VIP tier and cashback rules.
- The transaction appears as completed in your Card transaction history.
What Happens if a Transaction is Refunded?
If a merchant issues a refund:
- The refund is processed as a separate card transaction.
- The refunded amount is credited back to your Card balance after the merchant completes the refund process.
- Refunds typically take 2–3 business days, although some merchants may take longer.
- Any cashback earned from the original purchase may be adjusted or reversed according to the Bitunix Card Cashback Terms.
Why Does the Final Amount Sometimes Differ Slightly?
For purchases in foreign currencies, the final amount may differ slightly from the authorization amount because:
- Visa exchange rates may change between authorization and settlement.
- The merchant may submit the final settlement amount later.
- Some merchants (such as hotels, gas stations, or car rentals) may place a temporary authorization hold before charging the final amount.
- This is normal behavior for Visa card transactions.
