I get this cordinate translation... (Out in the middle of the woods. Wrong conversion.)
N42 39.235437 E23 23.265315

Or this... (Looks like a factory that makes things. Winner!)
N42 39' 23.5437" E23 23' 26.5315"

Front of building next door to the factory... "CEN"? CUCMEMA (System for electronic payments.)
Whole area is an industrial area, factories and offices... Neighbor, stated above, might be related.

Or this... (Out in the mountains. Wrong conversion)
N42.39235437 E23.23265315

You gave us this... (Out in the middle of a sand-pit. Wrong conversion. But close!)
N42.6586, E23.394714

So someone in Bulgaria is playing with an assembled board, at a factory office... What does that have to do with the price of tea in China? I doubt they would be making them in the USA, or they would cost thousands more.

Not sure about the CC thing, but I am sure that might have to do with reducing CC fraud/loss, for them. Or they just might not have CC setup yet. (It is expensive to accept CC's, and more expensive when you count the number of online CC frauds buying these things with stolen credit-cards.)

They give receipts for the transaction, which is enough for legal prosecution, if needed. These are not blind-transfers, to ghost-recipients, in a foreign country. Cool that you snooped the EXIF data though. You must be a frequent visitor to 4chan or reddit. (Part of investigation is actual investigation, not just looking at random data and making assumptions based off individual components. I could have looked at that ash-tray and told you the photo was from Bulgaria.)

NOTE: That same board, which WAS in Bulgaria, is now on the desk in the videos on google, in the Pennsylvania, USA offices. Same board, screws, power-supply... No Bulgarian ash-tray.

Just had to add that.
