Gift Card Tracking App Development

I need an iOS app for tracking gift cards in my business. The app should allow me to auto populate numbers to gift cards, keep track of their balances, and auto subtract amounts by entering dollar amounts as they are used. It should also help me monitor employees who enter gift card information.

Key Features:
- Assign unique numbers to each gift card
- Track and update card balances
- Deduct amounts when used
- Monitor employees entering data

User Authentication:
- Required for employees
- Email/password and single sign-on (SSO) needed

Ideal Skills:
- iOS app development
- Experience with secure user authentication systems
- Background in developing tracking or management apps

Looking forward to your proposals!
