Most retail and hospitality businesses stopped keeping much cash on hand years ago, which means when the internet drops, so does the ability to take payment at all. A busy Saturday afternoon outage, queue building, EFTPOS down, is exactly the kind of downtime failover connectivity exists to prevent.
Why This Matters More for POS Than a Normal Office
An office losing internet for twenty minutes is an inconvenience, staff switch to phone hotspots and carry on. A retail till or hospitality POS losing internet for the same twenty minutes, during a busy trading period, means turned-away customers and lost revenue in real time, not just delayed emails. Cloud-based POS systems in particular depend entirely on connectivity to function at all.
How Failover Actually Works
A dedicated 4G or 5G failover device sits alongside the primary internet connection and automatically takes over the moment the main line drops, without staff needing to notice or intervene. This is different from a manual backup like a personal phone hotspot, which depends on someone remembering to act and isn't built for continuous transaction traffic. Businesses already running SD-WAN often have this capability built in as one of multiple connection paths.
Where This Matters Most
- Retail - see our guide to IT support for retail businesses for the broader picture.
- Hospitality - covered alongside POS security and PCI compliance.
- Gyms and studios - membership check-ins and payments both depend on the same connection, see our gym and fitness studio IT guide.
- Any business without a manual, offline payment fallback - which today is most of them.
Setting It Up Properly
Failover connectivity is only as good as its coverage, worth testing 4G/5G signal strength at the actual site before relying on it, particularly in areas with patchy mobile reception. Where mobile coverage itself is unreliable, Starlink is worth considering as an alternative or additional failover path.
Frequently Asked Questions
How often does internet actually go down for most Perth businesses?
Rarely for extended periods, but even a short outage during a busy trading window is enough to turn away customers who don't carry cash. The cost isn't the frequency, it's that even a brief drop lands at the worst possible moment for a business that can't take payment any other way.
Does failover happen automatically, or does staff need to do something?
A properly configured failover setup switches over automatically when the primary connection drops, without staff needing to notice or intervene. If switching requires someone to manually plug something in, it's not really solving the problem it's meant to solve.
Is a mobile phone hotspot a reasonable backup?
It works in a genuine emergency, but it's not a real solution, personal hotspots aren't designed for continuous EFTPOS traffic, don't have business-grade reliability, and depend on someone's personal phone and data plan being available and charged.
Does this apply to businesses using cloud-based POS systems specifically?
Yes, arguably more so. A cloud-based POS system depends entirely on internet connectivity to function at all, unlike some older systems that could process transactions locally, which makes failover connectivity more important, not less.
We can set up automatic failover so an internet outage never means a closed till.
