Electronic Shelf Label Technology
Improves Retail Efciency
FG22 Wireless 2.4 GHz SoC
The Challenge
To increase the efciency of retailers by eliminating
time-intensive manual store-wide pricing updates
and correcting price discrepancies between the shelf
label and point-of-sale.
The Solution
Using the FG22 Series 2 Wireless 2.4 GHz SoC to
develop a wireless electronic shelf label capable of
managing store-wide price automation and reducing
operating costs.
The Result
Developing the InforTab e-paper display, a secure
and capable electronic shelf label capable of delivering force this to one line to avoid wrapping fast data
transmission across store networks for automated
price and information updates.
Current Inefciencies in
the Retail Experience
We all know the universal shopping experience where
you’re in line at the grocery store and the cashier makes
a request over the intercom asking for a price check on a
particular item. If this hasn’t happened to you, you’re at
least familiar with this situation as it has been depicted
countless times over the years in media. It’s generally an
attempt at humor – someone is making an embarrassing
purchase and they’re mortied when the store is let in
on their secret. Other times it’s a way to show someone
in a frustratingly slow checkout line that is stopped in
its tracks while the price of bubblegum is tracked down
by who knows how many supermarket insiders. Either
way, this scenario has been playing out in our real lives
for so long that we instantly identify with the plight of the
shopper. This is a problem virtually every retail store has
to deal with, and with the wide availability of network
connectivity and low-cost sensors and computing
technology, it’s on the verge of being solved once
and for all.

Wireless Solutions Ideal for
Improves Retail Efciency
South Korean-based RAINUS set out to provide retailers
with a way to update prices throughout the store in real-
time, maximizing their operating efciency and improving
the in-store experience for shoppers. Founded in 2014,
RAINUS is now one of the fastest-growing companies
in the world and their products, InforTab, InforTab+,
and +Touch are bringing electronic shelf label (ESL)
technology to store owners in virtually every sector,
including drug stores, health and beauty supplies, and
consumer electronics. The problem retailers in all of these
areas have in common is they are all looking for ways
to improve efciency. Managing price changes for every
product store-wide is time consuming and can take days
doing it manually depending on how large the store is and
how many different products it carries. Another challenge
is reconciling pricing discrepancies between the point-
of-sale (POS) system and the paper label on the product.
With InforTab, RAINUS makes it possible to update prices
automatically and change them in real-time, eliminating
hours of tedious manpower through a concentric network
system that requires minimum infrastructure cost and
the capacity to manage a high number of ESLs.
From a shopper’s perspective, they can see the
right price and information at the right time. Using
near-eld communications (NFC) embedded
inside InforTab provides a personalized digital
experience for shoppers by allowing them to use
their mobile phones to access product details.
Electronic Shelf Labels
Performance was a key factor in selecting Silicon Labs
as a partner for InforTab, as was nding a solution that
could scale with the quantities needed for large retail
stores. Silicon Labs’ FG22 Wireless 2.4 GHz SoC,
which features a 38.4 MHz Arm® Cortex®-M33 core
with TrustZone and a high-performance radio, was an
ideal t due to its size, ultra-low-power, and cost.
Leading Smart Retail
Technology Innovation
The high-performance architecture of InforTab is
one of the things that sets InforTab apart from its
competition. Recent benchmark testing has placed
it in a leadership position among electronic shelf
label technology and these tests are leading to rapid
adoption by leading retailers that have recently deployed
hundreds of thousands of individual InforTab ESLs with
the lowest server specication. At this time RAINUS
is the only provider that can support this many ESLs
with a single server system all while providing the
highest level of accuracy and robustness within the
industry. While RAINUS is focused on electronic shelf
label technology, as demands grow in other sectors
along with retail, the company expects to see more
opportunities to integrate smart retail technologies and
bring their expertise to bear on other IoT applications.
