Gift cards are the preferred way of giving and receiving gifts. They carry a monetary value that can be redeemed for gifts at your favorite store.
Onyx GiftCards are “Open Gift Cards” which means that they can be redeemed at multiple merchant locations. They are standard credit card size, can fit into the average wallet and made of PVC plastic. Onyx GiftCards are Barcoded for security and safety for the consumer and bear a disclaimer at the back.
Onyx Giftcards can be bought with a branded Card backer which is black in colour and is designed to fit the card. There is an area to write a brief message to the recipient as well.
The PayPal Sandbox accepts only PayPal's own published test card numbers. Real credit and debit cards are declined in the sandbox by design, so testing online requires a sandbox buyer account plus one of PayPal's fake card values. You can run a full checkout, capture, refund, and decline flow without ever touching a live card.
PayPal documents a set of fake card numbers for sandbox testing. Each one uses any future expiration date, any three or four digit security code, and any valid-format billing ZIP code.
Payment method card values change occasionally, so confirm the current list in PayPal's official sandbox testing documentation before you build a test suite around specific digits.
The sandbox is a separate environment that never contacts card networks or issuers. A live card number has no matching record in that environment, so the transaction is refused at validation. The same rule applies to expired, cancelled, or random numbers you generate yourself.
Repeat the flow in a fresh browser profile each time, because sandbox cookies can trap a logged-in buyer and hide the card form.
PayPal provides dedicated test values that trigger specific outcomes such as insufficient funds, expired card, or processor decline. Use those values in negative-path tests instead of inventing numbers. For authentication flows, sandbox scenarios let you simulate a challenge that succeeds, fails, or is abandoned.
Sandbox test cards have no purchasing power anywhere outside the sandbox. Real card data must never be entered into a test environment, and buying, selling, or using card numbers you do not own is a federal crime in the United States.
Build your tests with sandbox accounts, sandbox credentials, and documented test values. That combination covers approvals, declines, refunds, and authentication without exposing anyone's real account.
