Hi Mike, I have looked back into our documents, and the application worked (or was supposed to work) as follows: you took a picture of the barcode, which you then sent to a specified e-mail address, which then replied you with an url per sms, which you had to follow to get the information on the painting that was already there on the wall in the first place, thanks to Alfredd Barr decades ago. But since you had to take a picture of the image, and not scan it, you were dependent on the amount of light in the museum, which, being at night, was not very illuminated.
But, as the press release stated, this was a pilot. Maybe we should add kamikaze.
