FAQ
What are the benefits of uCards supporting BSC top-ups?
BSC (BNB Chain) is the third-largest chain for USDT circulation after TRON and ETH. Supporting BSC top-ups means you can withdraw USDT from decentralized exchanges (like PancakeSwap, Biswap) without needing a cross-chain bridge, saving on bridge fees (typically $1-5) and waiting time (10-30 minutes). This is especially convenient for users who frequently use BSC DeFi.
Is Dupay’s fiat top-up channel good?
Dupay supports fiat top-ups via bank transfer and other methods, which is convenient for users who don’t hold cryptocurrency. However, fiat top-ups typically have higher fees (2-5%) and longer processing times (1-3 business days). If you already hold USDT, topping up directly with uCards is faster and more economical.
Can both platforms be used simultaneously?
Yes. Many users hold virtual cards on multiple platforms. We recommend using uCards for daily online spending and subscription payments (enjoying zero KYC and low fees), and using other platforms’ physical cards for in-store spending scenarios. They don’t conflict — choose based on your needs.
How long is uCards’ card validity period?
uCards virtual card validity periods depend on the card type, typically 1-3 years. Before expiration, the platform will remind you to renew or replace your card. The advantage of virtual cards is that they can be replaced at any time, without the hassle of physical damage or loss.
What should I do if a payment is declined?
Payment declines are usually related to the merchant’s risk control policies, not the card itself. We recommend: 1) Try using a card from a different card network (e.g., switch from Visa to Mastercard or Discover); 2) Ensure the card has sufficient balance; 3) Check that the billing address is correct. uCards provides three card networks, giving you more options to try.
Which platform has faster customer support response?
Both platforms offer online customer support. uCards’ advantage is that since no KYC is required, you won’t encounter verification-related support issues. Top-up issues only require providing the transaction hash for quick resolution. In practice, uCards has high problem-resolution efficiency.
