Hmm I don't remember receiving many receipts in China. I spent 3 months there over two occasions a couple years ago. Taiwan's implementation appears more successful to me. Fapiao means receipt, so that makes sense. There is some required hardware or software but doesn't seem any more cumbersome than a credit card machine and printer. Nearly every shop has them in TW.

Edit: reading further I see China is rolling out their lottery in more areas the last few years
