Title: Dear mobile payment pitchers of HN,<p>Why would I want to pay for anything with my phone, rather than a card or cash? Please enlighten me.<p>Specifically,<p>(1) How is this more convenient than using my card or cash? I don&#x27;t buy the argument that carrying a wallet is an inconvenience. A card takes virtually no space.<p>(2) Why would I want to trust my smartphone, which has a battery life of about a day, with the ability to pay for something in a critical situation. My card and cash does not run out of battery. Furthermore, I have had three different smart phones die on me permanently in the last two years. I don&#x27;t want to be stuck somewhere and not be able to afford a taxi because my phone is dead.<p>(3) Why would I trust information about my purchases with a company like Google. They already know most things about me, but how does it benefit me to also give my purchase data over to them? So they can ad retarget me more easily? Fuck that. What&#x27;s next, my vital signs uploaded to Facebook in real time?<p>Thanks.
