It “fails to read card,” reads too many cards in wallet (despite setting it as the default transit express card), or says “done” on my end, but not on the reader’s end (which means a driver is still staring at you waiting for you to pay, and a lot of impatient riders glaring and shouting suggestions for holding your phone at different angles and positions on the reader). Since cash isn’t accepted on buses during pandemic precautions, you’re basically screwed unless you manage to pay down your hop balance to zero, ditch HopFastpass , and pay as you go with a credit or debit card on Apple Pay.
Read other reviews. This is a common problem. Customer service may tell you to go buy a physical card, for which they will charge you. $3 might not seem like a big deal, but when you already paid for an item, and then loaded funds into the service, it’s unethical to say the fix is to go pay for it again.
