Bank notes, particularly US dollars, are accepted in most countries around the world.
When visiting a foreign country for the first time, you might not be able to access banks, credit card machines or ATMs for a while (e.g. in rural or secluded areas).
In some countries, the locals only accept cash as payment.
Overseas banking-related fees might be high, and it helps to purchase small things with notes and coins instead.
You can buy foreign notes at your nearest FNB branch.
You should order your foreign notes at least 24 hours in advance.
Due to the cost involved in handling cash, foreign notes are not sold or repurchased at the same rate as other foreign transactions.
