<h3>About</h3>
My journey with LoyCart POS began in 2011, shortly after the initial release of WooCommerce. As a brick-and-mortar store owner, I immediately recognized the immense potential of building a simplified, seamless retail solution directly on top of such a powerful platform.
This project was a labor of love shared with my co-developer and dear friend, Kia Loy. This plugin is dedicated to his memory, as he sadly passed away in 2015. Kia’s passion and expertise are woven into the very fabric of LoyCart, and I am committed to maintaining his legacy through this work.
If you find value in this plugin, please consider making a donation. All proceeds will go directly to supporting Kia’s family.

<h3>Tips & FAQ</h3>
Here are some helpful tips and answers to common questions for LoyCart POS users:
How do I enable dark mode? 
– LoyCart POS automatically detects your system or browser dark or light mode preference based on the pos appearance Settings. You can also toggle dark mode using the toggle switch in the wordpress top bar menu.
How do I add or update products? 
– Add or edit products in WooCommerce as usual. Changes sync instantly to the POS grid. Use the barcode scan feature for fast product lookup.
Why is my product image missing? 
– If a product has no image, the POS displays a WooCommerce placeholder. To add an image, edit the product in WooCommerce and set a featured image.
How do I process a refund? 
– Click the Refund button in the cart, enter the original order ID from the customers receipt, and follow the guided steps. Refunds are validated for accuracy and security.
Can I use store credit/loyalty? 
– Yes! Enable Store Credit in POS Settings. Customers earn and redeem credit via WooCommerce coupons, visible in their My Account area.
What if my barcode scanner isn’t working? 
– Ensure your scanner is in keyboard mode. You can also use the built-in camera scan button in the POS search bar for mobile/tablet devices.
How do I print receipts or labels? 
– Use the Print buttons in the POS. On iOS, use the Share icon if the print dialog does not appear automatically.

Ifthenpay

ifthenpay does not offer built-in recurring billing. This plugin makes recurring memberships work by creating simple, easy-to-understand payment periods. When a period is paid, the membership continues; if not paid, MemberPress marks that period as “Lapsed” and the system waits for the end-customer to “Update” their subscription by making a manual payment for the next computed period. Periods are computed sequentially so customers never lose paid time — the next period is only created after the previous one is completed. An admin may also change the subscription status if needed.
In plain terms you get: 
* One-time payments and recurring memberships (period engine) 
* Partial refunds you control 
* Merchant backoffice (basic sales & refunds) on web + mobile 
* Secure automatic payment confirmations (no card numbers stored)
All settings are made in MemberPress and in your ifthenpay Backoffice. The plugin is built so store owners can manage payments without needing deep technical knowledge.
<h3>Key Features</h3>
<ol>
<li>Period-based recurring (sequential, preserves paid time)</li>
<li>One-time payments (standard purchase flow)</li>
<li>Automatic payment confirmation (fast access)</li>
<li>Lapsed period handling with manual Update action</li>
<li>Admin partial refunds (future/unconsumed periods)</li>
<li>Multiple local payment types (cards, wallets, transfers)</li>
<li>Merchant backoffice (basic sales & refund reports)</li>
<li>Security first (signed callbacks, no card data stored)</li>
</ol>
<h3>How Period-Based Recurrence Works</h3>
<ol>
<li>User purchases a membership with a cycle (e.g. monthly).</li>
<li>The plugin creates the first payment period and a payment reference for that period.</li>
<li>When payment is received, the period is marked paid and the next period is prepared. Periods are computed sequentially to avoid overlap and preserve any paid time for the customer.</li>
<li>Admins can generate or edit periods from the transactions screen.</li>
</ol>
<h3>Requirements</h3>
<ul>
<li>An active ifthenpay merchant account.</li>
<li>A Gateway Key for MemberPress (request this from ifthenpay support/helpdesk).</li>
<li>The payment methods you want enabled on that Gateway Key (your ifthenpay backoffice lets you choose).</li>
<li>WordPress 5.0+, PHP 7.4+, and MemberPress installed.</li>
<li>HTTPS (SSL) enabled on your site.</li>
</ul>
<h3>Refund Policy Management</h3>
Scope: refunds apply only to future or unconsumed paid periods (no retroactive time reimbursement). 
Process: 
* Admin inputs desired refund amount per transaction/period. 
* Optional min/max limits can guide consistency. 
* Approval required before issuing ifthenpay refund or internal credit note.
<h3>External Services</h3>
This plugin integrates with the ifthenpay payment platform to process payments for MemberPress memberships. ifthenpay is a third-party service that provides secure payment processing for various methods including cards, wallets, and local bank transfers.
<ul>
<li>
ifthenpay Backoffice & Integrations
<ul>
<li>What it is and what it is used for: The ifthenpay Backoffice is the merchant dashboard for managing payment integrations. The plugin uses the ifthenpay API to retrieve account configuration, generate payment links, activate webhooks, and process refunds.</li>
<li>What data is sent and when:</li>
<li>During setup: Backoffice Key and API Token (stored securely in site settings) to authenticate and retrieve available payment methods.</li>
<li>During payment processing: Minimal transaction details including transaction ID, user identifier, amount, and subscription details to generate payment references.</li>
<li>During refunds: Backoffice Key, request ID, and refund amount to process partial refunds.</li>
<li>End-User License Agreement (EULA): <a href="https://ifthenpay.com/eula/" rel="nofollow ugc">EULA</a></li>
<li>Privacy Policy: <a href="https://ifthenpay.com/politica-de-privacidade/" rel="nofollow ugc">Privacy Policy</a></li>
</ul>
</li>
<li>
Callbacks / Webhooks
<ul>
<li>What it is and what it is used for: Webhooks (callbacks) are used for automatic payment confirmations. When a payment is completed, ifthenpay sends a signed notification to the plugin to update the transaction status in MemberPress.</li>
<li>What data is sent and when: Only upon payment completion: reference IDs, payment status, amount, payment method, and request ID. No sensitive card or bank details are transmitted.</li>
</ul>
</li>
</ul>
All network requests are performed server-side over HTTPS. Sensitive credentials are stored in site options and are not publicly exposed. The plugin does not store raw card numbers or full bank account details.
