Ticket touts have been warned tough new measures will stop them profiteering from the Ryder Cup rush.
A 10-point security system has been introduced as part of extensive efforts to prevent fraud and inflated ticket prices.
The warning came as The Courier discovered one supplier claiming to have four-day season passes available.
Despite being advertised on the official competition website for £430, they were being offered on an American website from $2,025 or £1,342.48 plus a $370 (£245.29) booking fee.
Meanwhile, resale marketplace ticketsnow.com claims to have the same package available and “guaranteed” at $2,340 (£1,554.96).
Demand for the briefs is expected to far outstrip supply, so several methods have been adopted to ensure golf fans aren’t left out of pocket.
Those hoping to watch the Ryder Cup, which takes place at Gleneagles next year, must complete a two-part registration process before they are even entered into the ballot.
This includes providing a photograph as proof of identity, something which organisers say is “vital” in preventing fraud.
A Ryder Cup spokesman said: “There will be 10 distinct measures in place to prevent ticket fraud and transfer.
“The most significant of these is the inclusion of on all general admission tickets of the purchaser’s photograph.
“This will be checked at the course and is the single most effective measure available in the prevention of fraud and black market sales.
“Other measures include unique watermarks and barcodes.”
Similar measures were used for the 2010 Ryder Cup and helped to cut the number of tickets being sold on for “extortionate” prices.
“It is therefore a proven method and is becoming increasingly common at major events,” the spokesman added.
“While we appreciate some extra effort is required, by including photographic registration we know that only eligible applicants will be included in the ticket allocation process.”
