In open systems, a virtual terminal (VT) is an application service that:
Contents
- Allows host terminals on a multi-user network to interact with other hosts regardless of terminal type and characteristics,
- Allows remote log-on by local area network managers for the purpose of management,
- Allows users to access information from another host processor for transaction processing,
- Serves as a backup facility.
PuTTY is an example of a virtual terminal.
ITU-T defines a virtual terminal protocol based on the OSI application layer protocols. However, the virtual terminal protocol is not widely used on the Internet.
Virtual Terminals for payment card processing
This term is also used to refer to web interfaces for processing card not present transactions. Such terminals allow call centre agents to enter a customer's credit card details to take a payment. KNown as card-not-present payments, merchants or customers enter credit card payment information within a terminal to complete payments. This makes a Virtual Terminal the ideal solution for real estate agents, professional services, online payments and other industries.
