seems to me people here carelessly swipe their wallet everywhere. like the from door to buildings.
in the usa, there are lots of skimming machine that can steal your card info. lots of fraud in general. i lost some money on my credit card when i was living in US.
i take my Octopus out of my wallet each time before i use the Octopus , anywhere.
it seems HKese dont worry.
am i too paranoid?
