ATLANTIC CITY - Mobile technology was the theme of the 17th annual Hospitality Trade Show on Tuesday at Boardwalk Hall.

More than 100 vendors set up booths at Boardwalk Hall to meet prospective clients and catch up with old ones. Several promoted their products designed to help customers improve efficiency or open new markets.

In keeping with the popular topic of mobile gambling at the East Coast Gaming Congress, vendors such as Gtech Corp., of West Greenwich, R.I., displayed the latest European casino offerings: slot machine play via tablet or desktop computer.

"It's available all over Europe," said Adam Olrog, marketing manager for Gtech, which runs lotteries and mobile gambling for European casinos.

"It's a huge opportunity. We provide the software for the casinos," he said. "It's operated exactly the same. People play in their car, at the swimming pool - literally anywhere you can think."

The company eMarker LLC, of Nashville, Tenn., provides electronic markers that replace paperwork at casinos to speed credit approvals for customers and improve the efficiency of bookkeeping.

The state Division of Gaming Enforcement has approved the system for use in New Jersey casinos. Revel was the first Atlantic City casino to employ it, eMarker spokesman Ed Sieffert said.

"We wanted to make it as convenient as possible. Patrons get chips in hand much faster," he said.

Vendors use the annual hospitality trade show to meet individually with casino purchasing agents.

Douglas Rothman, vice president of M. Rothman Group in Ramsey, Bergen County, sells flat-screen televisions, sound systems and other electronics to hotels across the country.

One new appliance that is attracting interest is called the Cell Blaster, a toaster-sized machine that uses ultraviolet light to sterilize cell phones.

Rothman put his smart phone in the shiny, reflective device, which takes about 30 seconds to kill germs.

"It's the same technology banks use to sanitize money," he said.

Some vendors offered more traditional services. Rich Fire Protection, of Pleasantville, installs fire-suppression systems in hotels and commercial buildings in New Jersey and Pennsylvania, including nearly all of Atlantic City's casinos.

"You don't want to turn your back on your own back yard," said James Ferrante, of Somers Point, a senior account executive.

The company has been installing more range-hood systems designed to cut down the risk of commercial-kitchen fires, he said.

Atlantic Cape Community College promoted its continuing education, particularly for businesses that want to train employees in computer skills or customer service, said Sherwood Taylor, the college's director of work force development.

"We offer companies leadership training, management training and corporate training. And we can customize training for businesses," he said. "We are a resource for them."
