Onyx Gift Cards is a Grenadian company designed to introduce, market and manage gift cards systems in Grenada for retailers and corporations. We are enthusiastic about the effect and influence we will have on the local market. We intend to expand our systems regionally with a range of product offerings and services.
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.
A dummy card number is a fake sequence of digits that passes format checks but links to no real bank account. Developers use numbers such as 4111 1111 1111 1111 or 4242 4242 4242 4242 to test checkout pages, refund logic, and error messages in sandbox mode. Every one of them declines on a live payment gateway because no issuer will authorize the charge.
Test numbers exist inside developer tools. They move no money and cannot buy goods from a real store.
A payment form checks a card number against rules before the request ever reaches a bank. Matching those rules is what makes a test number useful for front-end and validation testing.
Card numbering follows ISO/IEC 7812, which sets the structure of the issuer identification number and the account number. The same standard describes the Luhn checksum used as a first filter. Payment processors reserve unused numbers inside those ranges for sandbox testing.
Because the ranges are public, any string of digits can pass a Luhn check. A form that accepts a number proves nothing about whether the card behind it is real.
Payment processors publish their own sets. Stripe, PayPal, Braintree, and Authorize.Net all keep lists in their developer documentation. The numbers below appear in those public lists and work in sandbox mode for the processors that publish them.
Processors also publish numbers that force specific declines, such as a generic decline, an insufficient funds response, or a lost card response. Those let you build error handling without waiting on a real bank.
A live gateway sends the number to the card network for authorization. The network looks up the issuing bank, and the bank checks the account, the balance, and the card status. A test number has no account behind it, so the request returns as declined or invalid. Format alone never completes a purchase.
A dummy card number cannot buy anything. It carries no funds, no account, and no issuer approval. Any attempt to use one on a live store ends in a decline.
Buying, selling, or using another person's card data is a federal crime in the United States under 18 U.S.C. § 1029, which covers counterfeit access devices and card fraud. Stolen CVV data sits in that category. Legitimate testing never touches real cardholder data, and PCI DSS rules limit how real card numbers may be stored or processed at all.
No. Using published test numbers inside a sandbox is standard practice. Using card numbers that belong to other people, or buying stolen card data, is fraud and carries criminal penalties.
No. Real stores route every payment through a live gateway and an issuing bank. Test numbers decline.
A dummy number is fake and works in sandbox mode only. A virtual card is real, issued by a bank or a fintech, tied to a funding account, and usable for live purchases.
Yes. Processors publish them at no cost in their developer documentation. No purchase or signup is needed to read the list.
The numbers do not expire. The expiry date you type into a sandbox form still has to be a future date, and many processors publish a fixed test date such as 12/34.
