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 testing monitoring software detects scripted attempts to validate stolen card data. It watches authorization traffic for patterns: many small charges, rapid card-number changes, high decline rates, and repeated device or IP data. The software alerts fraud teams or blocks traffic at the payment page. It is a fraud-prevention control for merchants, not a tool for card validation.
Track the count of blocked attempts, false positives, chargeback rate on blocked traffic, and time from first suspicious event to block. A pilot on one checkout path gives a baseline. Measure approval rate change before and after deployment. Card testing attacks can produce thousands of authorization attempts in minutes. A rule set that blocks 100 attempts per hour may still miss a distributed attack across 500 IP addresses.
Monitoring software cannot prove that a card is stolen. It flags behavior. Attackers change IP addresses, device fingerprints, and amount ranges to avoid fixed rules. Merchants need payment processor data, server logs, and chargeback records to confirm a pattern. PCI DSS requires logging and monitoring of payment system components. Access to logs and card data must follow PCI DSS scope rules.
