General Information


The official language of the symposium is English.

Currency and Foreign Exchange

The basic currency of Korea is won (KW). Notes include KW 1,000, KW 5,000, KW 10,000 and KW 50,000 denominations, while coins include KW 10, KW 50, KW 100, and KW 500 denominations. Foreign bank notes and traveler’s checks can be exchanged into Korean won at foreign exchange banks, airports, hotels and other authorized money exchange outlets. Hotels usually exchange currencies such as the US Dollar, the Euro, UK Sterling and Japanese Yen. In the case of other currencies, visit commercial banks. The exchange rate is subject to market fluctuations.


The standard voltage in Korea is 220 volts, 60hz. The outlet has two round holes and is the same type used in France, Germany, Austria, Greece, Turkey, and many other countries. If you do not have a multi-voltage travel adapter, you can borrow one from your hotel’s front desk. If you want to buy one in Korea, you can do so at a duty-free shop, convenience shop at Incheon International Airport.

Credit cards

Credit cards including VISA, Master Card, American Express, Diners Club and JCB are accepted at major hotels, department stores, restaurants, and retail outlets. However, VISA, Master Card and JCB are only acceptable for the payment of ISRS2020 registration fees at registration desk.

Business Hour

Government office hours are from 09:00 to 18:00 during the week. The five-day workweek has been introduced in Korea and government offices are closed on weekends. Business hours for banks are generally from 09:00 to 16:00 on weekdays. All banks close on Saturdays, Sundays and public holidays. Automated teller machines are widely accessible.

Tip & Tax

Tipping is not a regular practice in Korea. Service charges are often included in the bill for rooms, meals, and other services at hotels and upscale restaurants. Koreans occasionally do tip when they are especially pleased with the service. Upon request, visitors can receive nearly 10 percent VAT refunds for purchases at the “Duty Free Shopping” outlets. Goods must be taken out of Korea within three months of purchase to be eligible for a tax refund. Only foreign tourists in Korea can apply for this tax refund. Visitors can receive a refund on a receipt for a minimum purchase of KW 50,000 (around US$ 40). To receive this refund, present refund receipts with the purchased goods at the customs desk at the Incheon International Airport when departing. These receipts can be cashed in at the Cash Refund Office in front of the Airport Duty Free Shop.
