You know... I was thinking about doing this somehow, except I&#x27;d either need to pay someone to use their ticket machine, or become my own official lottery licensed thingy.<p>Now the interesting part: I&#x27;d accept credit cards without a second guess. Why?<p>First thought is &quot;fraudulent transactions to redeem... duh.&quot; Yeah, that&#x27;s totally true, but here&#x27;s what you do:<p>When someone purchases the ticket online, you give them their numbers (obviously); you don&#x27;t give them their barcode to redeem. Let&#x27;s say they win: To receive the ticket&#x27;s barcode, they must present the card they used to purchase. If they don&#x27;t, well, you&#x27;ve got yourself a winner.
