Background of Implementation

Jack Company, a casual fashion brand, previously distributed coupons via direct mail several times a year. However, while printing and postage costs were high, the redemption rate remained around 20%, posing challenges for sustainable promotional strategies.

To address this, the company shifted toward leveraging LINE—a key customer touchpoint—to transform promotions into an experience where customers participate on-site upon visiting the store. The goal was to create a mechanism that integrates smoothly into in-store operations and drives in-store purchases.

Campaign Overview

The implemented campaign was a 'win-every-time' gacha lottery accessible via QR codes placed at checkout counters and fitting rooms.

The participation flow is as follows:

Scan the in-store QR code

Participate in the gacha

Receive a coupon after adding the official LINE account

Use the coupon immediately in-store

By instantly revealing whether a prize was won while displaying the discount rate only after coupon receipt, the design naturally channeled users' curiosity into LINE registration and coupon acquisition.

Quantitative Results

The campaign achieved the following results:

Coupon usage rate: ~70% — significantly surpassing previous direct mail campaigns

LINE friend count: ~20% increase — approximately 3,000 new friends added during the campaign period

Additionally, stores where staff actively promoted LINE registration and gacha participation showed higher customer traffic and sales growth.

Unexpected Outcomes

Notably, even among customers aged 40–60, there was almost no resistance to the QR code-based gacha campaign.

Moreover, the gacha functioned not only as a discount mechanism but also as a conversation starter between staff and customers. Staff reported that it was 'easier to engage customers compared to traditional coupons.'

Future Outlook

Going forward, the company plans to implement segmented messaging based on behavioral data such as 'gacha participants' and 'coupon users.'

Additionally, beyond in-store promotions, they aim to design cross-channel customer experiences by integrating e-commerce referrals and diagnostic content, evolving into a sustainable promotional strategy.

Summary

Jack Company's case demonstrates how shifting from 'distributing coupons' to 'designing an in-store experience of participation and immediate use' can significantly enhance promotional effectiveness.

'Croissant' enables such experiential designs through a no-code platform, making it suitable for various industries and business types engaged in in-store promotions.

Could your company also consider a QR-based campaign that encourages immediate in-store usage as part of the customer experience?
