Managing a card

Precondition:

• An account must be created on the Wirex Pay Chain.
• A user entity must be created, with KYC completed and the phone number confirmed.
• A card in an active status is available.

Abstract:

Wirex Pay Cards function as non-custodial cards, meaning that the associated assets are held in a non-custodial wallet within the Wirex Pay Chain infrastructure.

The Wirex Pay API provides essential features to enhance user control and security. These include customizable spending limits, advanced security options such as card lock and unlock functionality, and the ability to view detailed records of all transactions made with the card. These features empower users to manage their cards effectively while maintaining visibility and control over their spending activities.

Step 1: Asset Balance Requirement

To use the Wirex Pay Card, an asset balance is required in the non-custodial wallet linked to the card. You can obtain this balance by transferring assets from a supported blockchain using the Bridge service. The Bridge allows for seamless asset transfers into the Wirex Pay Chain.

Step 2: Associate a Card with an Asset

Each Wirex Pay Card can only be associated with one specific asset at a time. To specify the asset linked to the card, and API callis required. This step ensures that the card operates using the designated asset for all transactions. Make sure to choose the asset that aligns with your intended use case or currency preference.

Step 3: Set Daily Spending Limit

By default, Wirex Pay Cards haven't a daily spending limit. You will setup the daily limit must via an API call. This step allows for greater flexibility and security, enabling users to define spending controls in alignment with their needs.

Step 4: Maintain Card Status

Wirex Pay Cards offer essential security features that allow users to manage their card status effectively. Users can lock, unlock, or close their cards via specific API calls:

Block Card

To temporarily disable a card, use the Block card API call. This feature is particularly useful if the cardholder suspects unauthorized activity or wants to suspend the card’s usage for any reason.

Unlock Card

To re-enable a card that was previously locked, use the Unblock card API call. Unlocking the card restores its functionality, allowing the user to resume normal usage.

Close Card

If a card needs to be permanently deactivated, this can be done using the Close card API call. This step should be taken if the card is lost, compromised, or no longer needed.

These options provide cardholders with control over their card’s availability and security, helping to prevent fraudulent activities.

Step 5: Control Transactions

To maintain visibility and track spending activities, Wirex Pay provides the ability to view all transactions related to a specific card. Users can access a list of transactions, including details such as dates, amounts, and merchants, via the Transactions API call.

This feature allows users to stay informed about their spending patterns, monitor transactions for discrepancies, and maintain an organized record of their financial activities.
