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 credit card test number is a fake card number that works only inside a payment gateway's sandbox environment. Gateways publish these numbers so developers can run charges without touching a real card. The best known example is 4242 4242 4242 4242, a Visa test number that returns an approval in Stripe, PayPal, and most other sandboxes.
A test card number looks like a real card number and passes the same Luhn checksum check. The gateway reserves it, so no bank issues it and no cardholder can be charged. Test numbers exist so you can build checkout pages, refunds, and subscription billing without moving money.
Each gateway maps its test numbers to a result. One number returns an approval, another returns a decline, a third forces a 3D Secure challenge. That mapping lets you exercise every branch of your payment code.
Numbers differ between processors, so pull the list from the docs of the gateway you use.
Stripe's sandbox uses 4242 4242 4242 4242 for a successful Visa charge. 4000 0000 0000 0002 returns a generic decline. Stripe lists further numbers for insufficient funds, expired cards, and 3D Secure flows.
PayPal's developer sandbox issues its own test cards inside the test account dashboard. Braintree, which PayPal owns, publishes a separate list in its developer docs.
These gateways document their own ranges. Use the number from your provider instead of a number copied from a forum post, because the response codes differ from platform to platform.
A test number lives in a sandbox database. A real card number lives at an issuing bank and links to a credit line. The two never overlap, because card networks reserve the ranges that gateways hand out for testing.
Storing real card data brings PCI DSS obligations. Test data does not, which is one reason to build the whole flow with sandbox numbers first.
Test numbers cover the full lifecycle, not just the first charge. You can create a subscription, let it renew, refund it, and simulate a dispute. Some gateways ship numbers that force a renewal failure so you can check your dunning emails.
Yes, when you point it at a sandbox you control or at your own test account. No, when you aim it at a live payment endpoint or use it to probe a system you do not own.
Running real card data through a payment page to see which accounts are still open is card testing, and in the United States that falls under 18 U.S.C. 1029, the access device fraud statute. Buying or selling card data is a crime on its own. A sandbox number holds no value and cannot work on a live gateway.
Card testing is the practice of running small charges on stolen card numbers to learn which ones still work. The people behind it then sell or reuse the live cards. Merchants absorb the damage through chargeback fees, processor penalties, and account termination.
Test numbers give developers a safe way to build. They give a fraudster nothing, since the numbers are published in public docs and rejected by live systems.
The charge fails with a card declined or invalid card number error. No money moves. Check the API keys in your config, then rerun the flow against the sandbox.
No. Live gateways reject them because no issuer recognizes the number.
In the developer documentation for that gateway. Look for a page titled test cards or test payment methods.
You can build one that passes Luhn, but it returns a generic decline unless it matches a number your sandbox knows about.
No. They stay valid for as long as the gateway keeps them in its sandbox, and the expiry date you type does not matter.
