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.
Test card numbers are fake, publicly published card numbers that payment processors hand out so developers can test checkout flows without ever touching real card data. This guide explains what they are, how sandbox testing works, and how to use them correctly, plus why they should never leave a test environment.
A test card number is a placeholder primary account number (PAN) issued by a payment gateway for its sandbox. It passes the same format checks as a real card, including correct length and a valid Luhn checksum, but it is tied to a test merchant account and cannot move real money.
Test PANs follow the same ISO/IEC 7812 structure as issued cards, so they fit the length, prefix and checksum rules your form validation already enforces. What separates test from live is the credential, not the digits: a test API key or sandbox merchant account routes the request to the simulator, while a live key sends it to the real network. Expiry fields can be set years ahead and postal codes are usually accepted with any well-formed value. Never type genuine cardholder data into a sandbox, because PCI DSS obligations follow any environment that stores, processes or transmits a real PAN.
This is a digital product, so nothing ships and there is no waiting on a courier. Access unlocks immediately after checkout, and any updates to the reference material are included. If it is not what you expected, contact support within the stated return window for a refund; no physical item needs to be sent back.
Yes. They are issued specifically for development and QA, they are not linked to any real account, and they are rejected the moment they are sent to a live endpoint.
Usually because the request is hitting live mode with a live key, or because you deliberately picked a number that simulates a decline. Check your API key first, then the expected result for that number.
Only in your payment processor's own developer documentation. Any list that promises working numbers outside a documented sandbox is not something to rely on.
