I moved to India 2 years back, and surprisingly, in daily life it looks so much advanced here! Here we order groceries, food, medicines, everything online, and you think of a way of payment, and it's there. "Paytm" changed the way of digital payments forever in stores (even roadside sellers and stalls). In US I used Google Wallet to pay in stores through my phone, but with paytm it's even easier. You scan vendor's barcode, type the amount, and click 'Send'. That's all. Then came UPI, which removed another layer of uploading money beforehand. Going cashless has become a breeze.
