What is ONYX GiftCards?

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.

What is a Gift Card?

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.

What a card expiry test tool does

A card expiry test tool checks the expiration date field on a payment form. It verifies the format. It checks the month range. It checks if the date is in the future. It does not confirm that a card is active. It does not confirm that a card is authorized. It does not verify ownership.

How payment processors test expiry

Stripe, Adyen, and Braintree publish test card numbers. These numbers work only in sandbox mode. The expiry date on a test card is an input. The sandbox returns a success or decline code. A decline code can simulate an expired card. A test tool can use these codes to confirm form behavior.

Limits of an expiry test tool

An expiry date is a 4-digit field on a card. The field does not prove the card is valid. It does not prove funds are available. It does not prove the card is not stolen. A test tool cannot check a real card without a payment processor. Using a tool to test cards you do not own is fraud. US law, 18 U.S.C. § 1029, covers access device fraud.

When to use a card expiry test tool

Use it during checkout development. Use it during quality assurance. Use it to check error messages. Use it to check input masks. Do not use it to validate a card for a live purchase. The payment processor does that step.
