Learn why EFTPOS terminals fail and how proper EFTPOS maintenance prevents downtime. KWIK eCASH helps keep your business payments running smoothly.
EFTPOS systems are essential to the daily operations of Australian businesses, from retail stores and hospitality venues to pubs, clubs, and small merchants. When a terminal fails, even briefly, it can interrupt sales, inconvenience customers, and cause operational delays. Proper EFTPOS maintenance is therefore crucial to ensuring seamless payment processing and minimising downtime.
1. Network & Connectivity Issues
Network disruptions are among the most common reasons EFTPOS terminals fail. Since most devices rely on internet connectivity—whether through Wi-Fi, Ethernet, or mobile data—a weak or unstable connection can prevent transactions from processing. Interruptions may occur due to provider outages, restricted Wi-Fi networks, or hardware faults in routers and modems.
Common signs of network-related EFTPOS issues include:
• Slow transaction processing
• Error messages such as “Connection Error”
• Frequent disconnections or failed approvals
A reliable and dedicated internet connection is essential for maintaining efficient payment flow.
2. Hardware / Power / Charging Problems
Hardware issues often arise from power interruptions, battery faults, or general wear and tear. If a terminal loses power unexpectedly or cannot charge correctly, it may shut down mid-transaction or fail to start at all. This can be particularly disruptive in high-traffic environments such as restaurants, bars, and retail counters.
Typical hardware-related causes include:
• A degraded or faulty charging dock
• Loose or damaged charging cables
• Power surges are affecting the terminal’s components
Ensuring the terminal is consistently charged and protected from electrical issues greatly reduces the risk of downtime.
3. Software Issues & Device Maintenance
EFTPOS terminals regularly receive software and firmware updates designed to enhance performance, security, and compatibility. If updates fail, are interrupted, or are not installed, the terminal may freeze, lag, or generate errors.
Key software-related risk factors include:
• Missed overnight updates due to low battery or power disconnection
• Device memory issues
• Outdated firmware is affecting transaction flow
Routine maintenance, including cleaning, inspection, and confirming that updates have been applied, helps ensure optimal device functionality.
4. Integration or Software-to-POS Mismatches
For businesses using integrated POS and EFTPOS systems, communication issues between the two platforms can cause failures or delays. A sale may be approved on the terminal but not recorded in the POS system, leading to discrepancies and reconciliation challenges.
Common causes include:
• Network interruptions between POS and EFTPOS
• Software updates that break the integration link
• Incorrect configuration during setup
Testing and monitoring integration settings is essential for businesses relying on connected systems.
5. Card & Transaction-Related Failures
Not all failures stem from the EFTPOS terminal itself. Sometimes, the card or the issuing bank is the source of the problem. Cards may be expired, damaged, or blocked, and insufficient funds can also result in declined transactions.
Other frequent transaction-related issues include:
• Incorrect PIN entry
• Card chip or tap-and-go reader problems
• Processing timeouts during authorisation
Understanding these distinctions allows businesses to troubleshoot more efficiently and provide better customer service.
