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.

How it Works?

  • Buy an Onyx Gift Card at these local stores
  • Give your gift card to friends, family, co-workers, etc.
  • The recipient can shop at our select merchants nationwide
  • Your friends, family, co-workers, etc. will present their gift card at checkout to pay for your item(s)
  • They will walk away happy with the best gift ever...the gift of Choice

Why ONYX GiftCards?

  • Save TIME. No need to run around looking for the perfect gift
  • Redeem from a variety of business island-wide. We will continue adding businesses as fast as ONYX grows.
  • ONYX Gift Cards do not expire
  • Cards are valued at convinient amounts to meet every need and occasion

This guide compares CVV verification tools from the merchant's point of view—what the online selling experience is like when accepting cards. CVV checks confirm the three-digit code matches the card issuer's records, which helps stop fraud before it costs you inventory.

Top Pick: Stripe for Online Sellers

After comparing each provider, Stripe is the strongest CVV verification service for online merchants. It runs a CVV match on every transaction, responds instantly, and lets you automatically decline mismatches. You can also set custom rules to accept low-risk mismatches or route them for review. Stripe works well for both startups and large catalogs.

How We Compared

We used one test checkout flow across three providers and graded five factors:

Stripe

Stripe validates the CVV automatically inside each transaction request. The API returns a cvc_check status of pass, fail, or unavailable. You can build custom alerts or use the default Risk Radar to decline failed checks. No extra charge for CVV checking—you only pay the standard card rate.

PayPal Payments

PayPal's Advanced Credit and Debit Card service is a convenient second option, especially if you already run your store through PayPal. It requests CVV during checkout, shows the result in the transaction details, and adds seller protection when eligibility criteria are met. The integration is straightforward, but you have less fine-grained control over how to manage borderline mismatches than with Stripe.

Square Online

Square is the easiest to set up if you also sell in person. Online payments include automatic CVV verification, and you can turn on a stricter filter for card-not-present transactions. Square is best for sole proprietors who want a no-code dashboard and are okay with minimal customization.

Which One Should You Pick?

Choose Stripe first if you want full control, fast responses, and detailed decline reasons. Choose PayPal if you need a trusted, all-in-one account and seller protection. Choose Square if you run a small store and prioritize simple onboarding above advanced rules.
