Get instant virtual cards in about a minute for online shopping, subscriptions, and everyday digital payments. Viewunce is a digital payment platform that provides easy access to virtual cards for online use. It is designed for people who need a simple and convenient way to pay for products and services online without relying on a physical card. With Viewunce, users can create virtual cards that work like regular payment cards on supported websites and mobile applications. These cards can be used for online shopping, software subscriptions, entertainment services, travel bookings, advertising platforms, and other digital purchases where virtual cards are accepted. Viewunce offers two types of virtual cards: One-time virtual cards Create a card for a specific purchase or short-term use. One-time cards receive a single load and cannot be topped up after creation. Reloadable virtual cards Create a reusable card that can be topped up when additional funds are needed. Reloadable cards can also be frozen and unfrozen from the app, giving users more control over how their cards are used. Users can pay for a card with supported USDC or USDT stablecoins. Viewunce currently supports selected blockchain networks, including Base, Solana, and Tron. The app displays the required asset, network, amount, payment address, and applicable fee before payment is made. Viewunce does not provide cryptocurrency trading, swapping, brokerage, or investment services. Users cannot buy, sell, exchange, or store cryptocurrency in the app. Supported stablecoins are accepted only as a payment method for funding a virtual card. Where available, users may also pay by Nigerian naira bank transfer. Payment availability may depend on the user’s location and the services supported by our payment providers. After a payment is confirmed, the virtual card is made available in the app. Users can securely view their card details, check the available balance, review card activity, and manage supported card controls from one place. Sensitive card details can be protected using Face ID, Touch ID, or the device’s authentication method. Viewunce also makes it easier to organize online spending. Users can create separate cards for different purposes, such as subscriptions, personal purchases, business tools, or one-time transactions. Card activity and payment status are displayed in the app, helping users keep track of how each card is being used. The amount, payment network, and applicable fees are shown before confirmation. Users should always send the exact amount using the network displayed in the app. Blockchain and card processing times may vary depending on the selected network and service provider. Viewunce is built to make virtual card access simple. Choose a card, select an amount, complete payment, and receive a card that can be used online—typically in about a minute. Whether you are paying for a subscription, purchasing software, booking a service, or shopping online, Viewunce provides a practical way to manage digital payments without carrying a physical card.
