Walmart Canada has debuted a new checkout system called "fast lane" that lets customers avoid cashiers and registers.

"Skip the checkout and skip on home," reads an ad for the fast lane, which is designed for users of the company's mobile app, called My Walmart.

Here's how it works: My Walmart users scan items with their phones as they shop. Once they are finished shopping, they click "checkout" to receive a barcode.

Next, they scan the order barcode at one of four scanning stations in the "fast lane."

This action will charge their credit card on file.

Finally, just before exiting the store, customers will present a mobile receipt to a worker tending the fast lane.

The "fast lane" could be built into future stores. The system has debuted in a newly opened store in Toronto that Walmart says will serve as a prototype for future store renovations.

"With our new urban supercenter concept, we're continuing to position ourselves as a leader in store design and retail innovation," Lee Tappenden, president and CEO of Walmart Canada, said in a statement on the new Toronto store.

"We're introducing new partners, testing new and innovative technologies, integrating e-commerce with bricks-and-mortar and updating our assortment to improve the customer shopping experience and to appeal more to young families in urban markets."

The "fast lane" is similar to Scan & Go, a now discontinued Walmart US program that let customers scan and pay for items on their mobile phones. With Scan & Go, however, Walmart customers didn't have a designated checkout area, or "fast lane."

Walmart killed Scan & Go last year and replaced it with Check Out With Me, which enables roaming Walmart employees to process customers' payments using handheld devices.

Walmart isn't the only company experimenting with cashierless checkout.

Amazon's brick-and-mortar Amazon Go stores allow customers to pick up and pay for items without scanning any product barcodes. And Kroger has launched its own version of Scan & Go, called Scan, Bag, Go.
