Heuristic
Keep a bounded payment fallback for short outages
Payment systems can fail independently of your bank balance.
When it fits
- Every ordinary purchase depends on one card, phone wallet or online banking path.
When to avoid it
- Cash security, inflation, local payment infrastructure and emergency risks differ; choose a modest context-appropriate fallback.
Why it matters
Maintain a small, locally appropriate fallback for short electronic-payment outages—such as some cash or a second payment method—sized for essential near-term needs rather than hoarding. Keep it secure and review whether the method is still usable.
An example
Enough local cash for basic transport or food during a short outage can be more useful than discovering every nearby terminal is offline.
Check your result
One temporary payment-system failure does not immediately block basic household needs.
Keep this limit in mind
- Cash security, inflation, local payment infrastructure and emergency risks differ; choose a modest context-appropriate fallback.
Evidence and sources
Supports
Ready.gov preparedness materials recommend including some cash because ATMs or card systems can be unavailable during extended outages.
