OPT!M is an area-specific app designed for creating an "order list" of desired products for purchase. Users can select the items they wish to buy through the app to generate a QR code. By simply presenting this QR code at the sales counter, they can easily place their order.
The process leading up to a purchase is as follows:
1. Activate and check in with the app in the designated area.
2. Review the necessary information, add products to the list, and create the order list.
3. Display the QR code for purchase on the smartphone.
4. At the local sales counter, scan the QR code, exchange the products, and complete the purchase.
Please note that if the planned sales quantity is reached, products may be sold out even within the sales period. Kindly understand this limitation.
