My wallet... in Singapore or in Melbourne? 
When I work the Evening shift back in Melbourne, I won't carry a
bag nor a wallet when I go to work. I'll just chuck A$10-20 in my
pocket with my housekeys, then pop in a stick of lip gloss and
lipstick in the other, and off I go. This is for safety - I don't
want to be seen as a target for mugging when I'm off work late at
night and the streets are dark and quiet. No bag for
them to snatch and run off.
But ok, typically, my wallet would have my favourite photo of the
day of my favourite person / pet of the day, my R.N. registration
licence, discount / membership cards, ATM cards, Credit Card, Debit
Card, ... that's it!
