NFC Delivers Hemp Product Authentication, Information to Consumers

By Claire Swedberg

The Near Field Communication-enabled packaging that PearlCBD employs for its goods helps consumers confirm the authenticity of a lotion or capsule, as well as view its certification data, and learn about what cannabidiols are and how they are used.


A California hemp-based cannabidiol (CBD) startup is selling products with what it calls intelligent labels that leverage Near Field Communication (NFC) technology to deliver information to its customers. PearlCBD, owned and operated by Origin Labs, began manufacturing and selling its goods this year, each with a unique ID number encoded on a passive NFC tag built into a label. PearlCBD sells all of its products with NFC-enabled labels so that users can verify a product’s authenticity before buying it, as well as view lab test results regarding ingredients and other content.

CBD products are sold legally in stores throughout most of the United States, though they must meet restrictions dictated in the 2018 U.S. Farm Bill. They must contain less than 0.3 percent tetrahydrocannabinol (THC), the compound that provides the narcotic effect of cannabis. Anything with a higher THC level is classified as marijuana, which is federally illegal, though legal in many states. Because CBD-based goods are still relatively new, the general public often lacks an understanding of what they are and what they consist of, says Danny Davis, PearlCBD’s CEO. They may also not understand what kind of certification is available for them to view before making a purchase, or what that certification means.

PearlCBD’s line of lotions, tinctures, creams and capsules.

Origin Labs aims to provide clarity as it sells its new merchandise. PearlCBD’s products are manufactured at the company’s FDA-registered lab in Florida. The firm recently released a series of lotions, tinctures, creams and capsules, and it provides technology to help consumers get acquainted with CBD and understand what is in each product. From the onset, the company wanted to use technology to help its customers make sense of what they were buying. There are regulations related to the sale of cannabis-based goods, Davis explains, but there is no way for consumers to easily know if a manufacturer has met those requirements when making a purchase.

Davis says he chose NFC as a means of providing consumers with proof that his company’s products are authentic, and to offer transparency “so they know what they’re putting in or on their body, with lab test results.” To that end, the NFC system is designed to educate customers. The PearlCBD line is now being sold by several major retailers, Davis says, and he expects that number to expand this year. “We believe that if we took a pharmaceutical product and gave consumers technology to understand it better,” he states, “they would then trust that product, and we can build brand loyalty.”

Many cannabis-based goods provide QR codes on their labels. Scanning a QR code with a mobile phone provides some information, Davis says, though most shoppers tend not to scan QR codes. What’s more, a QR code can be copied, meaning it cannot prove an item’s authenticity even if a code is scanned.

PearlCBD sought to provide more information that could change as necessary, including the Certificate of Analysis (COA) that includes details about the raw oil used in its product. That information can be difficult to understand, Davis says. “Most consumers don’t really know what they are looking for,” he states. For instance, some lab results are more meaningful than others. Davis estimates that 95 percent of cannabis products do not display post-formulation ingredients and testing results after they are manufactured, instead providing only the pre-formulation rating for the raw CBD oil. Thus, PearlCBD wanted to provide both pre- and post-formulation data to its customers.

The company buys its CBD oils through two suppliers, and multiple batches of oil may be mixed. “We have an aggressive process to get us where we need to be with our distillate,” Davis says, which involves keeping the THC level below 0.3 percent. The company wanted to find technology that could track what went into each product, so each PearlCBD package now comes with a 13.56 MHz NFC tag, compliant with the ISO 14443 standard, built into its labels. The tag, made according to specification by a third-party supplier, is embedded into the label rather than being affixed to an existing package or label after the product is containerized. That, Davis says, helps to prevent errors that could occur if an NFC tag were placed on the wrong bottle after it was filled.

The system starts with the grower. Typically, one of PearlCBD’s growers identifies which oils it has generated and are on their way to PearlCBD’s lab to be mixed. That information is forwarded to the lab so that the containers can be prepared in advance. The NFC-enabled labels can be printed onsite, with each NFC ID number linked to that specific product and the oil batches contained in it. Thus, once the lab receives the oil, the product can be certified, mixed and containerized using the label ID already commissioned for that merchandise, and the collected data is then stored in PearlCBD’s management software.

The product can be shipped directly to online buyers or to stores, Davis says. In either scenario, consumers can learn about it using their NFC-enabled smartphone, simply by tapping the phone near the label. The phone will then open PearlCBD’s dedicated website, which will invite them to enter the “PearlCBD experience.” If a user responds to the prompt with “Yes,” the system will link the NFC tag ID with the mobile experience and display the notification, “You’re authenticated.”

Next, the system asks the individual, “Would you like to see your lab test results?” If he or she replies, “Yes,” the phone will then display lab certification results, as well as a choice of videos about the product to explain how it is used. No app is required to access the NFC-based data, Davis says, adding, “I look at packaging as either intelligent or dumb. We want to give customers enough information about our product to make other [competing] products inferior.” With NFC-enabled packaging, he says, “We can be first-movers in technology.”

In the future, Davis says, the company may opt to expand its technology use, though such future plans are still conceptual at this stage. The solution has a patent pending for the NFC labeling, he reports, after which the company could sell the intelligent labeling system to other companies in the cannabis market or in other sectors.

“My hope is to license our technology to other users,” Davis states. “The sky is the limit when it comes to intelligent packaging.” He cites wine, liquor and tobacco products, which currently provide limited information to consumers when it comes to their ingredients and lab certifications. NFC technology can provide a variety of options for companies to help customers understand their products, and to build brand loyalty. “I’m a futurist—I’m excited for the potential.”
