Walking by talented street artists when you have no spare change on you can be tough. You may feel bad, but fewer and fewer people carry cash now. This is why you should download Upward.
Upward, a non-profit initiative, and its volunteers proactively talk to street artists, make them Upward Signs that tell their story, and by scanning the QR code on it, you can easily tip them a small amount with you credit card, debit card, or Apple Pay.
