Age verification is imperative for all online sales of age restricted products such as tobacco, e-cigarettes, wine and spirits. States such as Texas and Massachusetts have already passed regulations mandating that online retailers selling age restricted products verify consumer information against consumer databases to ensure that consumers are of legal age to purchase their products. Self-certification of age (e.g. having a consumer click a button or submit their age or date of birth) is not sufficient to maintain compliance with these regulations.

What is GDPR?
GDPR, General Data Protection Regulation, is a new privacy law that gives EU customers more control over their personal data. And, with fines of up to €20 million or 4% of annual revenue, GDPR is simply too important to ignore.
GDPR creates stricter rules on how EU customer data must be handled. Businesses handling personal data for EU customers must have a legally valid reason for doing so, and be able to justify this in simple terms. Meaning more transparency for EU customers, and greater protection of fundamental data protection rights.
