My wallet had become quite fat and heavy, so I decided to see how others were tackling this problem. Quite a few people were switching to minimal wallets, card cases and money clips. So, about a month ago, I decided to go minimal on my wallet problem.
First, I took out all the stuff from my wallet and decided which of those items I really needed. I pared it down to 3 essential cards and a few currency notes:
NETS card for monetary transactions.
EZ-Link card for commuting on buses and trains.
University card for access to university facilities.
After that, I picked up a tiny card case with 4 slots that could hold these items. Among the 4 items, the EZ-Link and university card never need to be removed out since they use RFID. And I was done!
This minimal wallet was so thin and small that I could not even feel its presence in my back pocket! It has been more than a month and the experiment has been a success. I am even thinking of skipping the lunch money, since I can keep that at my desk at work.
