Instant Cash Withdrawals without leaving the machine: Consequences?

The Rolling Good Times Online report on new technology that would allow gamblers to withdraw money instantly from their bank accounts without leaving the gaming machine or table.
Technology and Gambling: Faster Cash, But At What Cost? discusses the technology which is basically a wireless EFTPOS terminal which is used by an attendant to verify the player's debit or credit card and ensure sufficient funds are available to process the transaction. If successful the attendant would give cash to the player for immediate play.

A limited field trial has been approved in order to assess the impact the technology has on problem gambling rates, but casinos are already lining up for the technology which is the only at machine/table cash withdrawal method that has been successful to this point after in machine credit and debit card readers were deemed to have too significant an impact on problem gambling.
