The downfall of US brick-and-mortar commerce is overblown—despite sharp gains in e-commerce, which will nearly double between now and 2021, the lion’s share of purchasing continues to take place in-store. And that’s unlikely to change anytime soon, since the online environment can’t yet compensate for the reasons customers like brick-and-mortar shopping.

That means the point-of-sale (POS) terminal, which merchants use to accept payments of all types and to complete transactions, isn’t going anywhere. But that doesn’t mean it’s not changing. As merchants look to cut costs amidst shifts in consumer shopping habits, POS terminals, which were once predominantly hardware offerings used exclusively for payment acceptance, are evolving into full-service, comprehensive solutions. These new POS terminals are providing an array of business management solutions and connected offerings to complement payment services.This is where the smart terminal, a new product that’s part-tablet, part-register, comes in. Merchants are increasingly seeking out these offerings, which afford them the connectivity, mobility, and interoperability to run their entire business. And that’s shaking up the space, since it’s not just legacy firms, but also mobile point-of-sale (mPOS) players and newer upstarts, that offer these products.

As merchants begin demanding a wide variety of payment solutions, terminal providers are scrambling to meet their needs in order to maintain existing customers and attract new ones. This is leading to rapid innovation and increased competition in both the POS terminal hardware and software spaces.
