Just a few years ago, retailers considered smartphones the enemy of the in-store experience they were trying to create. Customers often whipped out their device to compare prices online and then walked out of the store to buy the same product elsewhere.

Today, stores are taking their cues from shoppers and now consider the smartphone their friend. They’re giving shoppers more control over the experience with smartphone app features that let customers do things like scan and pay, as well as download digital maps — and replicate the online experience.

Nike created a buzz last month when it unveiled two new features on its mobile app during the opening of its latest high tech store in New York City. One feature lets shoppers see details of every item displayed on a mannequin by scanning the QR code next to it. Then with just a click, they can have the looks delivered to a fitting room or a designated pickup spot without ever talking to a store clerk.

Another feature, instant checkout, lets customers who’ve stored their credit card information on their phone scan the barcode of an item, click the purchase button, then walk right out of the store.

Shoppers are increasingly using their mobile devices to make purchases. That was evidenced at the start of the holiday shopping season, when 33 per cent of online Black Friday sales were made on smartphones compared with 29.1 per cent on Black Friday last year, says Adobe Analytics, which tracks online spending.

“They’re browsing, they’re looking at content, they’re getting reviews and they’re transacting,” said Jeff Gennette, CEO of Macy’s, who expects the department store chain to hit $1 billion in mobile sales for the first time by year-end.

But there’s still room for improvement. Stores need to do a better job of promoting their mobile checkout while working out some kinks. They also need to make their in-store Wi-Fi service more reliable, analysts say.

Here are three problem areas:

KINKS IN MOBILE CHECK OUT: Walmart, Target and other large retailers have been sending workers throughout the busiest sections of their stores to check out customers with mobile devices. At Macy’s, shoppers can scan and pay for items using a new app feature on their own smartphones. From there, they must then go to a mobile checkout express line or a regular cash register and show the app to a worker, who will remove security tags from clothing.

But there are limitations to the services. For stores like Walmart and Target, shoppers can only use mobile checkout for a limited number of items; if they have a cart full of products, they’ll need to still go the cash register. And unlike Nike, many stores aren’t heavily promoting the service.

SPOTTY WI-FI SERVICE: Stores’ Wi-Fi service had been good enough for shoppers to tap into general information on their phones. But now it needs to be more reliable to handle all the digital content and services, according to Neil Saunders, managing director of GlobalData Retail, a retail research firm. Analysts say the connections are still spotty and are not consistent within the store, and the service gets worse when the store is crowded.

“They haven’t built the Wi-Fi to deal with all these functions,” Saunders said.

UNRELIABLE PICK UP SERVICE: Plenty of major retailers are offering easier ways for customers to pick up items ordered online beyond the service desk. And they’re using their smartphones to get alerts on when to pick up their purchases. But analysts say there are still problems of shoppers walking in and not getting the item they said would be ready.

Anthony Karabus, CEO of HRC Retail Advisory, a consultancy, surveyed 30 top retailers heading into the holidays and found the online pickup service wasn’t dependable because of a disconnect between the items the system tells shoppers are in a specific store versus what the retail actually has on hand.
