RFID is used for [[item-level tagging]] in retail stores. This can enable more accurate and lower-labor-cost supply chain and store inventory tracking, as is done at [[Lululemon]], though physically locating items in stores requires more expensive technology.<ref name="McKinsey">{{cite web |url=https://www.mckinsey.com/industries/retail/our-insights/rfids-renaissance-in-retail |title=RFID's renaissance in retail |date=May 7, 2021 |publisher=McKinsey |author1=Praveen Adhi |author2=Tyler Harris |author3=Gerry Hough}}</ref> RFID tags can be used at checkout; for example, at some stores of the French retailer [[Decathlon (retailer)|Decathlon]], customers perform [[self-checkout]] by either using a smartphone or putting items into a bin near the register that scans the tags without having to orient each one toward the scanner.<ref name="McKinsey" /> Some stores use RFID-tagged items to trigger systems that provide customers with more information or suggestions, such as fitting rooms at [[Chanel]] and the "Color Bar" at [[Kendra Scott]] stores.<ref name="McKinsey" />

Item tagging can also provide protection against theft by customers and employees by using [[electronic article surveillance]] (EAS). Tags of different types can be physically removed with a special tool or deactivated electronically when payment is made.<ref>{{cite web|url=http://www.controltekusa.com/controltek-news/benefits-of-rfid-in-theft-protection/|title=Benefits of RFID in Theft Protection – CONTROLTEK|website=Controltek|date=14 February 2014|access-date= 11 October 2017}}</ref> On leaving the shop, customers have to pass near an RFID detector; if they have items with active RFID tags, an alarm sounds, both indicating an unpaid-for item, and identifying what it is.

Casinos can use RFID to authenticate [[casino chip|poker chip]]s, and can selectively invalidate any chips known to be stolen.<ref>{{cite news|url=http://www.minyanville.com/businessmarkets/articles/bellagio-wynn-casino-rfid-gambling-las/12/15/2010/id/31714|title=RFID-Tagged Gaming Chips Render Hotel Bellagio Robbery Haul Worthless|last=Rohrlich|first=Justin|date=15 December 2010|publisher=[[Minyanville|Minyanville Financial Media]]|access-date=16 December 2010}}</ref>
