 About Zeal
 
 
 
 Zeal is addressing the critical challenge of untapped transactional data. At the moment, whenever a transaction is processed on a POS terminal (payment card machine), physical retailers have no idea who the paying customer is, unless they use a loyalty program. Think of when you go to a supermarket and you pay by card , unless you go to a supermarket that has a loyalty program and you get your loyalty card out, the POS terminal doesn't tell the retailer if you're a new or returning customer, demographics, gender, etc. Unlike e-ecommerce, in physical retail customer identification always had to be a separate step because the payment terminal is not built to self-identify the paying customer. Hence, a plethora of valuable data is lost or underutilized. With Zeal&rsquo;s advanced Smart POS plugin, the company integrates with POS terminals globally to provide payment acquirers and ISVs with a unique differentiator for their POS terminals. The merchants of our partners benefit from world-class data, analytics &amp; tools to predict consumer behavior using Artificial Intelligence, enabling merchants to unlock the full potential of transactional data.
