On a more serious note, how do you use your iPhone as a TAP card in the subway?

I’ve got about $25 on my TAP card in my wallet. Despite having my phone unlocked and Face ID approved, I encounter an error almost every time I try to use it at the receiver. Frustrated after 10 failed attempts, I ended up buying a physical card at Noho station yesterday.

However, on my way back at Union Station, I decided to try again. Surprisingly, it worked on the third attempt (after two errors). I noticed that the time it worked, I inserted it at an angle and passed it over the sensor rather than approaching straight on. Could this method have made the difference? Hard to say.

Does anyone else regularly use their phone for TAP payments and have tips to make it more reliable? Have others experienced a high failure rate of over 90%?
