The official Olympic credit card company, Visa, has processed more than $9.7 million in transactions from Homebush Olympic Park alone since the beginning of September.
Nearly $3.1 million has been withdrawn from automatic teller machines (ATMs) at Olympic Park during this period.
Bruce Mansfield, Visa's country manager Australia, said the company had installed 22 branded ATMs within the Olympic Park precinct to cope with the expected demand. These ATMs are currently being refilled at the expected rate of once a day.
"We have been promoting the Olympics for years and have a system in place that deals exclusively with transactions from the Olympic period. It is a complete stand-alone system with the latest Windows NT platform on all ATMs."
To assist Olympic visitors, Visa, in conjunction with Telstra, last week launched a wireless application protocol (WAP) ATM locator service for use during the Games and beyond.
Users throughout Australia with WAP-enabled mobile phones connected to Telstra MobileNet WebMode will be able to locate their closest ATM. To utilise the service, users enter either a postcode or city and street information. They are then provided with the location and details of the nearest ATMs.
"I don't know if we will begin talks with other networks to carry this service; we only have a relationship with Telstra at the moment," Mansfield said.
Concerning the taxi industry's dispute with Visa and the subsequent banning of Visa cards, Mansfield said he didn't think overseas visitors would be confused by the inability to use one of their cards to pay for a taxi trip.
"Most consumers don't use a credit card to pay for a taxi, they use cash anyway," he said.
"We have been having an ongoing dialogue with the taxi industry about the situation, but it is our policy that we don't allow merchants to implement a surcharge on transactions."
