I am certain that there is likely to be nobody reading this blog who has never been to a trade fair or industry event. Huge gatherings of like-minded individuals, peers or even just the curious jostle past one another, between extravagant stands paid for vendors promoting their wares.
The cost of such events is justified by the lead data which is acquired en masse via business card exchange and the scanning of visitor name badges, something sales teams hope to capitalise on later down the line. All that personal data and a well known European data protection regulation are sure to cross paths in dramatic style, post May 2018.
