Cardholder

CIT payment

CIT (Cardholder Initiated Transaction) is a stored-credential payment where a cardholder is actively participating in the payment. In this scenario, the cardhoder initiates a payment but does not need to enter their card details as the merchant uses the card details previously stored by the cardholder to perform the payment.

Stored payment method

A stored payment method is used when a cardholder authorizes a merchant to store the payment credentials for further payments. For example, a customer may opt to save their card at checkout. In this case a unique token - the credential - is generated by the Payment Gateway that links the customer's card number (PAN) to their ID in the store system (for example, to customer's login).

Customer

Installment payments

Installment payments are processed on a regular fixed interval according to a payment plan. For example, when a customer monthly pays a bill in small portions. Unlike recurrent payments, installment payments are done throughout a fixed period of time.

Merchant

A party selling goods or providing services through the eCommerce website (online store).

Merchant Portal

Merchant Portal or Personal Area enables a merchant to easily perform a wide variety of tasks using web interface. In Merchant Portal, the merchant can manage and monitor payments, configure payment options, or send an invoice with a payment link directly to a customer's email.

PCI DSS

The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard used to handle credit cards from major card brands. All companies that process credit card data must be compliant with PCI DSS. This requirement is also applicable to eCommerce merchants who outsource all payment processing to PCI DSS validated third parties, and who have a website that doesn’t directly receive cardholder data but can impact the security of the payment.

P2P payment

Two-step payment

A payment for goods/services made via the Internet with the use of bank cards that requires additional confirmation, i.e., payment is made in two steps. At the first step, the check of availability and holding of funds of the customer (pre-authorization) takes place; then, at the second step, the company either confirms to debit funds, or cancels holding of funds.

Session

Each session is associated with a specific amount and is initiated in the Redirect Integration scenario when the customer opens the payment page. The session ends upon successful payment or automatically expires with a configurable timeout.
