They sold miners through card read factory many moons ago. What do you think "smallest portable magnetic stripe card readers in the world" are used for? Many people on these forums have bought their miners and we've had photos from inside their factory, saw their FPGA to ASIC development hardware, if it's a scam, they went to a lot of trouble to hire a factory and fill it with mining hardware.

Of course they could fail. Building a board and putting someone else's chip on it it easier than building your own ASIC from scratch. We saw that happen to bASIC, they delivered FPGAs, but later failed to deliver on a subsequent ASIC project.
Many in the community thought Butterfly Labs would be a scam, but they delivered (eventually), on their promises.
If you don't want to risk money in a pre-order buy a 28nm miner from Technobit with PayPal, but even he gets scammer accusations!
It's just the nature of the Bitcoin market... More risk, more reward!
