I&#x27;ve always wondered - why was it so easy to replicate Square&#x27;s scanning device? Seems like about 6 months after they really started gaining traction, PayPal came out with their copycat triangle one, and then a cascade of copycats.<p>It went from not being a thing to there being tons of them overnight. I would imagine there would be somewhat of a barrier to entry, but it seems it&#x27;s a fairly easy device to create?
