## 개요

Type a campaign code and get a reward. Enter `WELCOME2026` in the field under **Redeem a campaign code** and press **Redeem**; 100 coins land in the wallet under **Where the coins land**. Each visitor can redeem once, and a second try or a wrong code is refused with the reason.

## 체험 방법

1. Read the rule under **Redeem a campaign code** and the redemption status ("You have not redeemed a code yet.").
1. Type `WELCOME2026` into the field (**Type a code**) and press **Redeem**; **Free balance** under **Where the coins land** goes up by 100.
1. Press **Redeem** again; it is refused with "You have already redeemed a code; each visitor can redeem once." and no coins are added.
1. Press **Start over** to clear your redemption so you can redeem again.
1. Type a wrong code such as `welcome2026` and press **Redeem**; it is refused because GS2 does not know the code (codes are case sensitive).

## 사용하는 GS2 서비스

- [GS2-SerialKey](/ko/microservices/serial_key/): The GS2-SerialKey campaign `WELCOME2026` is registered as a campaign code, and the redemption transaction checks the typed code against it.
- [GS2-Exchange](/ko/microservices/exchange/): A GS2-Exchange rate bundles the code use, the redemption count and the coin deposit into one transaction that commits only if all succeed; **Start over** is another exchange rate.
- [GS2-Limit](/ko/microservices/limit/): A GS2-Limit counter (maximum 1, never resets) counts the redemption and refuses a second one; **Start over** deletes that counter.
- [GS2-Money2](/ko/microservices/money2/): The 100-coin reward is deposited into the GS2-Money2 wallet as free currency.
