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 fake credit card number test uses a publicly published sandbox card number, such as 4242 4242 4242 4242, to confirm that a checkout form, payment gateway, or subscription flow behaves correctly without moving real money. These numbers work only inside a processor's test mode. Typing one into a live store is card fraud, not testing.
It is a quality check developers run against a payment integration before launch. The test number exercises validation rules, error messages, retries, refunds, and webhooks in a sandbox that never contacts a bank.
Because no real account exists behind the digits, an approval in test mode proves the code path works, not that a card is valid.
Payment processors publish them in their own developer documentation. Stripe, PayPal Braintree, Adyen, and similar providers each maintain sandbox card lists with fixed expiry dates and CVC values.
These numbers are intentionally shared so engineers can build and demo payment features. They are tied to the processor's test environment and are rejected anywhere else.
Each processor dictates its own accepted expiry and CVC values, so always copy them from the current docs rather than from a blog post.
The Luhn formula verifies that a string of digits has the internal structure of a card number. Many random sequences pass it, which is why format checks alone never authorize a payment.
A live transaction requires the issuing bank to match the number, expiry, CVC, and cardholder identity. Format validity means nothing at that stage.
Using a fabricated number against a live merchant is fraud, and U.S. law treats it as a federal offense under 18 U.S.C. § 1029. Attempts count even when the charge fails.
Buying, selling, or trading real card numbers and CVVs is a separate federal crime. Sandbox testing with your own merchant account is the only lawful use of a test number.
No legitimate source sells CVVs. Listings that claim to sell them are either outright scams that take your money, or criminal marketplaces that expose buyers to prosecution and to having their own data stolen.
No. Live gateways send an authorization request to the issuing bank, which has no record of a sandbox number. The charge is declined and the attempt may be flagged.
Yes. They are free for developers working in a processor's test mode, provided the merchant account belongs to you or your employer.
Yes, and that is exactly why Luhn is only a typo filter. Passing Luhn does not make a number usable for a real purchase.
