It is interesting to learn that we need to have large wallets to house all our cards - membership cards, credit cards, ID cards, mrt cards etc... Side compartments for coins and receipts too.
I realised today, having a large wallet is no longer a necessity. There are so many cards that can be installed into our phone apps including our debit and credit cards for payment purposes.
So, really I only have a small wallet with me to carry some cash, My ID card, one debit card and one credit card for personal self assurance purposes. In case where my phone is out of battery, I still have backup plan :)
How cool is that?
