Megastore Seongsu: Invisible Technology, Sharper Experience

Megastore Seongsu is a roughly 2,000 pyeong complex store spanning from basement level 1 to the 4th floor, housing Musinsa Store, Musinsa Standard, Musinsa Beauty, and Musinsa Kicks together. To customers it looks like a single Musinsa, but the system had to simultaneously handle pricing, discount, and reward rules for different shopTypes.

Four technologies were woven into a single flow to solve that complexity.

• ESL (Electronic Shelf Label) replaces paper price tags, syncing prices and promotions instantly from the system.
• Offline PDP opens in the app when a tag's QR code is scanned, showing real-time prices by membership tier, stock by option, stock at other stores, reviews and snaps, similar product recommendations, and even a wishlist feature. Because Musinsa Standard finds it difficult to attach store-specific QR codes at the production stage, it automatically recognizes the current store based on location.
• Self-POS is a self-checkout solution with custom-designed hardware, software, and spatial design, supporting multiple languages and Tax-Free, and even connecting non-members' simple SNS sign-up to first-purchase benefits.
• RFID automates payment, exchange, refund, and security tag release by identifying products through a combination of brand (Musinsa Standard) + 32-digit barcode rather than by recognition method, even during the transitional period when it coexists with barcodes.

For Musinsa Standard RFID products, payment, exchange, and refund are all processed through RFID logic, and the security tag is automatically released upon completion of payment. Some products are still operated using the existing hard tag method, but stoppages disappear from the customer's journey.

Ultimately, the design goal of Megastore Seongsu is not to put technology front and center, but to hide complex operations behind the scenes so customers can focus solely on products and brands. Once stabilized, the RFID logic will expand to standalone Musinsa Standard stores, and ESL and Offline PDP are also planned to expand to more stores.
