St Helena is a remote island in the South Atlantic (population just over 4,000) that has no credit card machines or ATM’s on the entire island. It’s cash only and they have their own currency that isn’t accepted anywhere else in the world. The bank was closed when we arrived so local establishments let us run tabs until we could get to the bank. When we went to the bank it had no security guards or bars on the windows or anything similar, and the teller used a small calculator to convert our currency. The island is beautiful with areas of desert and cacti as well as lush farming areas.
