Payments for Olympic tickets are slow coming in. Rong Jun, director of the Olympic Ticketing Center said that a “considerable” amount of people who have won tickets are yet to pay for them.

“In order to avoid cancellation of bookings, people must present their identity cards and ticket booking numbers to complete payment procedures at the 1,000 designated Bank of China branches as of Tuesday,” he said.

A deadline for payment is yet to be set and failure to pay for the tickets may result in people getting banned from purchasing tickets in the future.

A second round of tickets will go on sale in October, but people who are yet to pay for the first round will be illegible to buy further tickets. Payments can be made at the Bank of China or by Visa credit card.
