Octopus card

Everyone car­ries an Octopus card in Hong Kong, because it’s used every­where. When you take the bus, you pay the fare by tap­ping your wal­let (with Octopus card in it) on the scan­ner; the fare may change depend­ing on whether you take it before or after cross­ing the har­bour. Subway fares aren’t flat-rate either, so shorter routes are cheaper. The dis­tance you travel is tracked by scan­ning your card when you get on and again when you get off, and the appro­pri­ate amount is deducted.

Even vend­ing machines, park­ing meters, con­ve­nience stores, and restau­rants have Octopus scan­ners used to pay for their ser­vices. It’s also used as an iden­tity sys­tem, where stu­dents sign-in to class by tap­ping their cards on door scan­ners, or res­i­dents enter their apart­ment build­ings with­out need­ing a key.

The Chinese name for the card is “eight arrived pass”, because eight has spe­cial mean­ing in Chinese, espe­cially when it comes to direc­tions. The English name comes from an octo­pus hav­ing eight ten­ta­cles, and the logo is an infin­ity sym­bol that’s also in the shape of an eight. So clever.
