In Korea, there are self-service stores known as "unmanned stores" that operate 24/7. These stores offer a wide variety of snacks, drinks, and stationery at reasonable prices—often cheaper than supermarkets or convenience stores. What makes them even more appealing is that there's no staff rushing you to make a purchase.

Here’s a simple guide to using an unmanned store:
- After entering the store, browse and pick out the items you’d like to buy.
- On the packaging of each item, you’ll find a barcode. Scan the barcode using the round scanner or the handheld barcode reader attached to the self-checkout machine.
- The price will then appear on the screen.
- You can then choose to pay by cash or card. However, please note that some machines do not accept 50,000 KRW bills or small coins such as 10 or 50 KRW. Be sure to check the machine’s accepted payment types before proceeding.
- Once the payment is complete, you’re free to leave the store.

If you’re traveling or staying in Korea, trying out these unmanned stores can be a convenient and cost-effective experience.
They're a great example of Korea’s innovative and efficient retail culture. 💯
