Protecting EpoS systems: The real cost of a 10-minute retail blackout<\/h1>\r\n

Protecting EpoS systems: The real cost of a 10-minute retail blackout starts with recognising that checkout can fail in several different ways. A till may still work while card authorisation does not, or a power cut may take the whole checkout offline. \"A<\/p>\r\n

What to know<\/th>\r\nWhat to do<\/th>\r\n<\/tr>\r\n<\/thead>\r\n
A short EPoS interruption can cause lost sales, delayed sales and extra work.<\/td>\r\nEstimate lost sales and recovery costs separately, and record sales that are delayed until service returns.<\/td>\r\n<\/tr>\r\n
Power, internet, local network and payment-provider failures have different causes.<\/td>\r\nGive staff a simple decision path and a named person to contact for each type of problem.<\/td>\r\n<\/tr>\r\n
Offline mode does not automatically mean card payments will be authorised.<\/td>\r\nTest local sales storage, payment fallbacks and transaction synchronisation before an outage.<\/td>\r\n<\/tr>\r\n
Shared logins and uncontrolled refunds can make an incident harder to audit.<\/td>\r\nKeep individual accounts, suitable permissions and transaction records in place.<\/td>\r\n<\/tr>\r\n
A UPS covers a power interruption, not an internet or payment-service failure.<\/td>\r\nPlan for checkout equipment and connectivity as separate parts of business continuity. See our UPS guidance for EPoS systems<\/a>.<\/td>\r\n<\/tr>\r\n
Recovery is not complete when the till turns back on.<\/td>\r\nReconcile sales, stock changes and processor-confirmed payments before closing the incident.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n

What a 10-minute EPoS blackout puts at risk<\/h2>\r\n

EPoS means electronic point of sale. In a retail shop, the till software, checkout hardware, local network and payment terminal work together, so a failure in one part can interrupt checkout without taking every other part down. A short blackout can affect your business in several ways. Some customers abandon their baskets, some wait and complete purchases later, and staff may spend time managing queues, explaining the problem and recording transactions manually.<\/p>\r\n
