Remembering my wallet on hitting a payment wall

I want to go back to carrying my wallet again. As of now, I only need it because that is where I keep my subway card, though I know some people use their smartphone for the subway, too.

Since I have not downloaded the subway app yet, it pays to keep the subway card somewhere secure, so I know where to find it when I need it — in my wallet. Yet, so many times I have arrived at a subway station and reached for the lone subway card in my right jacket pocket, and then my left jacket pocket, and then, frantically, my trouser pockets, only to conclude that I must have left it in the different jacket I was wearing the day before.

This dependence on the phone for everything is a bit too much. The other day, I rushed out of office to go to an event and gave my consent to a smartphone upgrade, not realizing it would take ages. As a result, I could not book a cab or ride an e-bike. I had to run to the subway station as it was getting late. Thankfully, I didn't need my phone there. My phone was still upgrading when I reached my destination. Unable to check the phone map to figure out the quickest route to my event, I left by the exit situated farthest away, delaying me further.
