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.
Card test data is a set of card numbers, expiration dates, and security codes that payment processors publish for sandbox use. The numbers pass format checks such as the Luhn algorithm. They route to a simulated response instead of a bank. No funds move.
Gateway docs list separate numbers for each outcome: approval, decline, insufficient funds, and 3-D Secure challenge.
Both pass a Luhn check. Both use 16 digits for Visa and Mastercard. The differences sit behind the check digit.
A live PAN maps to an issuer and a funding account. A test PAN sits in a reserved block or a sandbox table. Issuers do not assign it.
Live data falls under PCI DSS. Test data does not, because nobody can use it to move funds.
Card testing is a different topic from test data. In a card testing attack, someone submits large volumes of stolen numbers to a merchant payment page. Small authorizations confirm which numbers work.
Signs include a spike in authorization attempts, a high decline rate, many cards from one IP address, and orders with mismatched billing data.
Controls that reduce it: rate limits per IP and per card, CAPTCHA on checkout, CVV and AVS requirements, 3-D Secure, and blocks on repeated declines.
Test number lists change without notice. Confirm against your processor's own documentation before you build a fixture.
