A success story where an AI avatar promoter dramatically boosted card sign-up conversion rates

About

Emart, one of Korea’s leading hypermarket, serves millions of customers across hundreds of stores nationwide. However, in an increasingly competitive offline retail environment, the company faced a key challenge: how to operate Hyundai Card sign-up campaigns more efficiently and consistently.

Historically, relying on human promoters led to inconsistent service quality due to shift changes, fatigue, and the high cost of repetitive training. While the credit card issuer demanded 100% accuracy in message delivery, human-led operations struggled to meet this standard.

To address this, Emart introduced Perso Interactive AI to create an Interactive AI Human–based promotional environment, where customers can engage in real-time conversations with an AI avatar inside the store. As a result, Emart achieved 24/7 stable campaign operations beyond human limitations and successfully improved credit card conversion rates.

Background

Previously, campaign operations relied heavily on human promoters, leading to persistent challenges such as service inconsistency due to fatigue and shift-based scheduling. During peak hours, gaps in customer response became more noticeable, while repetitive training costs continued to impact operational efficiency.

From Hyundai Card’s perspective, delivering campaign messaging—including legally required information—with complete accuracy was critical. However, maintaining this level of consistency through human staff alone presented structural limitations.

Consequently, E-mart adopted this solution to establish a stable operating environment capable of delivering consistent, high-quality messaging regardless of the hour and inducing card sign-ups through natural, real-time conversations.

Solution

Using Perso Interactive technology, Emart developed an AI Avatar optimized for its brand tone and in-store experience, deploying it across key locations within its stores.

The AI Avatar delivers consistent, fatigue-free interactions from store opening to closing—maintaining the same level of enthusiasm, accuracy, and engagement for every customer. It clearly communicates key promotional messages such as “instant discount coupons” and “cashback benefits of up to KRW 100,000”, while also responding instantly to customer inquiries. With real-time campaign integration, any updates to promotions are immediately reflected, ensuring that customers always receive accurate and up-to-date information.

Most notably, by integrating barcode scanning, the system allows customers to instantly check product information and seamlessly transitions interested users into the card sign-up process, creating an intelligent campaign environment that drives actual conversions beyond simple guidance.

Results

After implementation, under the same campaign conditions and timeframe, Emart achieved a significant increase in credit card conversion rates compared to human promoters. This was driven by the AI’s ability to engage every customer consistently, without fatigue, and at the optimal timing.

In terms of operations, the AI Station setup covered the entire extended store operating hours without interruption, completely eliminating response gaps during peak times. The campaign also secured high levels of trust by delivering legal disclosures and benefit conditions with 100% accuracy, strictly following the scripts without deviation.

Ultimately, this created a virtuous cycle where total operational costs, including labor and management, decreased while service quality was standardized at a high level, proving that Interactive AI events are an effective means of strengthening brand marketing.

It is a highly useful example for those who wish to move beyond simple advertisement displays and drive changes in customer behavior through real-time interaction with an AI Avatar.
