12 kinds of shopping tech that didn't exist 10 years ago but have changed retail as we know it

In 2015, Ralph Lauren debuted interactive mirrors in its New York City flagship that allowed shoppers to change the lighting of the room, request a new size or style, and browse other items. It was the first of its kind, and before long other retailers joined in trying the technology.

One of the biggest developments of the past decade was RFID technology — an acronym that stands for radio-frequency identification — which essentially functions as a smart label affixed to products. These "intelligent barcodes" allow retailers to better track inventory and better understand product life cycles.

QR codes have transformed retail in the past decade in a variety of ways, but most notably in the development of virtual stores like Amazon Go. Using Amazon's "just walk out" technology, shoppers enter the store while scanning a QR code and leave after they've collected what they need. Payments are then deducted through the app.

Instagram launched shopping in November 2016, which elevated the app from aspirational social platform to full-on e-commerce channel. The update allowed verified brands to develop shoppable posts that would direct users to their respective online shopping pages.

In March 2019, Instagram took this one step further by adding shoppable tools to Instagram Stories.

Just like facial-recognition technology can scan a face and use it to determine an identity, visual search made it possible for shoppers to upload a product and identify its origin or else find similar models.

In 2015, platforms like Pinterest began integrating visual-search technology into their platform. In 2017, Pinterest launched shoppable pins to help drive e-commerce conversions.

Though 3D-printed apparel once sounded like a futuristic novelty, it's now being used to make everything from Adidas sneakers to suit jackets.

The past decade brought major advancements in automation, including self-checkout that now goes beyond the 10-items-or-less Target line and features cashierless Amazon Go stores that you can just walk in and out of.

Chatbots became an integral part of the growth of automation this decade, with retailers experimenting with several types of bots, ranging from Facebook integrations and SMS messaging to concierge services on their websites.

Thanks to mobile providers rolling out services like Apple Pay and Samsung Pay, payments conducted via smartphones have exploded in the past decade. Today various retailers like Gap offer mobile pay, making it easier than ever for shoppers to make payments.

In the last few years, augmented-reality apps and screens have transformed how shoppers test beauty products everywhere from Sephora to traditional department stores like Nordstrom. Assisted by technology services like Modiface, these programs allow shoppers to virtually test out lipstick shades and eyeshadow palettes without needing to leave their home or grab a wet wipe.

Turns out body scanning isn't relegated just to airport security lines. Companies like Naked Labs developed 3D body-scanning tools that provide information on factors including weight, body mass index, and body measurements. By integrating this information into a smart-mirror format, users can virtually try on outfits and shop from the comfort of home.
