The two companies have bundled their solution expertise to help protect security for the data traffic passing from POS terminals to the central systems in retailing enterprises. TP.net, the store software from Wincor Nixdorf, encrypts transaction data at the store level.

One crucial factor in generating trust in the security of cashless payment systems is protecting credit card data from abuse. In many cases, reports of credit card theft and hacker abuse have seriously shaken the confidence of cardholders and retailing companies. The Payment Card Industry's data security standard (PCI) is a set of requirements that establishes standards for credit card transactions and is recognized by all leading credit card organizations. Retailing enterprises that transact business with credit cards must comply with these regulations. If they fail to obey the requirements, they may have fines imposed or restrictions passed on them.

Wincor Nixdorf and Cisco offer a solution package that helps retailers address some of the PCI standard requirements. TP.net encrypts transactions before they are dispatched to the data center, where the data is received by TP.net Enterprise on the central server. Cisco's portfolio offers protection of data in retailer networks, using a special client to help defend against the compromise of data from POS system to the store server and central systems.
