At the beach of the future, high tide will meet high tech.

Visitors will wear wristbands that automatically debit their bank accounts or credit cards to pay for beach access, food and parking. Garbage cans will e-mail cleanup crews when they’re ready to be emptied.

And people won’t even think about trying to sneak in: Beach checkers could scan the sands with handheld devices and instantly know who didn’t pay.

This southern New Jersey city plans to deliver a variety of public services and Internet access using radio-frequency identification chips and Wi-Fi wireless technology. The $3 million project is expected to be finished by next summer.

Beach badges, those plastic or cloth scourges of the Jersey shore could become a thing of the past. The beach access fees - $5 per day, $10 for a week, or $20 for the entire summer - will remain.

MySpace.com has found more than 29,000 registered sex offenders with profiles on the popular social networking Web site - more than four times the number cited by the company two months ago, officials in two states Tuesday.

North Carolina’s Roy Cooper is one of several attorneys general who recently demanded the News Corp.-owned Web site provide data on how many registered sex offenders were using the popular social networking site, along with information about where they live.

After initially withholding the information, citing federal privacy laws, MySpace began sharing the information in May after the states filed formal legal requests.

At the time, MySpace said it had already used a database it helped create to remove about 7,000 profiles of sex offenders, out of a total of about 180 million profiles on the site.

Cooper’s office said Tuesday, however, that now the figure has risen past 29,000.
