Overview

At the core of Wirecard ePOS solution is payment processing.

Core Integration chapter provides basic information in order to successfully process Payment Transaction.

Note

Payment Transaction (also called payment) is a monetary transaction with specific amount, payment method and type.

In context of Wirecard ePOS, every Payment Transaction is part of Sale:

• Purchase record (also called Sale-Purchase) is created when consumer purchases goods and/or services.
• Return record (also called Sale-Return) is created when consumer returns purchased goods back to merchant.

Important

Sale is central ePOS object. It must contain amount to pay and at least one payment transaction.

Additionally, Sale may include sale items (aka shopping basket), reference to merchant shop, reference to cash register and other optional sale-related information.

Wirecard ePOS supports following payment methods:

• Cash
• Card (EMV/Magstripe)
• Alipay (barcode payment)
• WeChat (barcode payment)

On top of traditional payment processing, Wirecard ePOS provides option to divide Sale total amount to multiple payment transactions.
