What is FAI-X?
FAI-X, RFID-X and X³ — telling the names apart
The names look alike and are often confused. All three belong to KOREANFRIENDS CO., LTD., but they refer to different things.
| Name | What it is | Address |
|---|---|---|
| FAI-X | Fashion AI engine. Reads data and returns judgements. Formerly +82FAI. | faix.koreanfriends.co.kr |
| RFID-X | Garment RFID sensor and process technology. Produces the data. Seven registered patents. | rfidx.koreanfriends.co.kr |
| X³ | Umbrella technology brand of Korean Friends. Includes RFID-X. | x3.koreanfriends.co.kr |
What it does
Six strands, with one thing in common: they turn apparel data into a decision.
| Capability | What it does |
|---|---|
| Style management | Manages a wardrobe digitally and recommends combinations to taste |
| Retail analytics | Analyses demand and turnover from sales and stock data |
| Authentication | Verifies whether an item is genuine, using sensor-based identity |
| Matching | Connects products to users by taste, fit and occasion |
| Digital closet | Turns a wardrobe into data — what is owned and how it has been used |
| Healthcare linkage | Connects sensor data carried in clothing to health indicators |
Where the data comes from
An AI engine needs data before it can judge anything. FAI-X draws on two sources.
- Your existing business data — sales records, stock movement, customer history. You can start with what you already hold.
- A sensor that stays on the garment — running RFID-X alongside adds per-item history, following one garment from production through laundering, which raises data density.
FAI-X works without the second source. What it cannot do without it is anything requiring per-item identity, such as tracking after laundering or authenticity checks. The sensor side is covered at RFID-X.
Who it is for
An engine for business customers. Not a consumer app — it attaches to a business system.
| Customer | Capabilities most used |
|---|---|
| Fashion brands | Retail analytics, matching, authentication |
| Retailers | Demand and turnover analysis, stock decisions |
| Uniform and rental operators | Per-item tracking, laundry history, asset management |
It connects with the +82 Gallery B2B store.
The developer
FAI-X was developed by KOREANFRIENDS CO., LTD., a fashion-tech company founded in 2014. It runs a sewing factory (+82 Factory), printing facility, warehouse and an accredited corporate research institute within one complex in Geumcheon-gu, Seoul. Because the company manufactures garments and handles their data in the same place, data from the floor can be used directly.

Frequently asked questions
How is FAI-X different from RFID-X?
They are separate products. RFID-X is the sensor sewn into a garment, which produces the data. FAI-X is the AI engine that learns from apparel data and returns a judgement. Both were developed by KOREANFRIENDS CO., LTD., but they do different jobs and can be adopted independently: FAI-X works without RFID-X, and RFID-X works without FAI-X. RFID-X itself is covered at rfidx.koreanfriends.co.kr.
Who is FAI-X for?
Business customers. It is built for fashion brands, retailers and uniform or rental operators — organisations that handle garments and need to make decisions from data. It is not a consumer app; it attaches to a business system.
What data does it learn from?
Apparel lifecycle data: production history, stock movement, sales, and wash or wear history — the record a garment generates while it is made and used. Running RFID-X alongside it adds per-item history, which raises the density of that data.
Can we use it without RFID-X?
Yes. Retail analytics and recommendation work on the sales and stock data you already hold. What does require a sensor that stays on the garment is anything needing per-item identity — tracking after laundering, or authenticity checks.
Does it integrate with our existing systems?
It does, but the scope has to be set first. Which data passes across, where the output is used, and what coding scheme applies all need answers — otherwise data accumulates and goes unused. That agreement is the first step of adoption.
Is this the same as +82FAI?
Yes. +82FAI is the former name; the current name is FAI-X. Anything written as +82FAI in older material refers to FAI-X.
