Need
- Customers are required to share their personal data with store receptionists in order to perform basic telecom operations (recharging, topping up, etc.)
- To get a new line or change PIN, customers should verbally provide sensitive information
- Customers could not verify their accounts or personal details directly; verification had to be done by the employee, as required by T-Mobile
- Customers asked to log in and sign trade-in disclaimers through email while waiting at the store
- Balance inquiries were handled manually by employees
Solution
A mobile application deployed on in-store tablets that integrates seamlessly with the POS. The POS can securely request customer input or display relevant messages through the app (credentials authenticated by the POS system without exposing any PII).
Value delivered
- Customer privacy and data security significantly improved. Sensitive information was no longer shared verbally or handled by store staff.
- The in-store experience became faster and seamless, reducing waiting times and minimizing manual entry errors.
- Compliance with T-Mobile’s IDV and authentication standards was achieved without adding friction to the customer journey.
- Customers gained greater control and confidence by interacting directly with the system through the tablet interface.
- Store employees were able to focus on service quality and sales rather than administrative data entry.
