Why Cash Persists In Card Economies

Cash use varies enormously between countries with similar levels of development. Assuming a card will work everywhere is one of the more expensive assumptions a traveller can make.

Card acceptance costs the merchant money

Every card transaction carries fees that fall on the business, and for low-value sales the fixed component can be a significant share of the margin.

Small operators with thin margins therefore set minimum spends, add surcharges where permitted, or decline cards entirely.

Where interchange fees are capped by regulation, acceptance is broader, which is why the same business model behaves differently across a border.

Trust and privacy shape household behaviour

In countries with a history of banking instability, holding cash is a rational precaution that persists long after the instability has passed.

Privacy preferences matter as well, and in some societies the traceability of electronic payment is a reason to avoid it that has nothing to do with convenience.

These attitudes are generational and slow to change, so cash use declines gradually rather than switching over.

Infrastructure gaps decide the practical answer

Card terminals need connectivity, and in areas with unreliable networks a business that cannot process a payment cannot make a sale.

Power reliability matters too, and cash continues to function through outages that stop every electronic system simultaneously.

Rural areas, markets, transport and small operators are where these constraints bite, which is why they are the last places to accept cards anywhere.

Some economies skipped cards entirely

In several regions payment moved directly from cash to mobile transfer systems built on phone numbers or codes rather than on card networks.

These systems are often domestic and closed, which means a visitor's card works nowhere useful and the local alternative is unavailable to them.

The result is a country that looks cashless from the inside and requires cash from a visitor's perspective, which is a common and confusing mismatch.

What this means for carrying money

The practical position is to establish before arrival whether cards are widely accepted, and to carry enough local currency for transport, small purchases and tips regardless.

Small denominations matter more than the total, since traders in cash economies often cannot change a large note early in the day.

Where cash is essential, the availability and reliability of machines becomes a planning question, particularly in rural areas where the nearest working one may be some distance away.
