The beauty salon group has about 8,000 corporate and franchise locations, most of which still use old point-of-sale dial-up machines. But Regis Salons is updating its network look with plans for a shared Web portal for business purposes and an Internet-based POS system that may include wireless LANs in the salons.

PCI rules for wireless indicate there needs to be a segmented network, Rominski points out, noting "The PCI Data Security Standard recognizes segmentation as a firewall." He adds that means each salon, if it uses wireless, will likely also install a firewall to be able to comply with PCI DSS.
