Visitors to the Forsyth County Public Library won’t need a card to go wireless anymore.The library board voted 4-0 on Wednesday to remove the requirement to enter a card number to access wireless Internet.The change to the “Internet Acceptable Use and Safety Policy” will allow anyone with a laptop or other personal device to receive a free connection within any of the three branches without a library card.The move was prompted by some issues with visitors’ electronic readers, or e-readers, not being compatible with the library’s system, said director Jon McDaniel.“When people started bringing in their e-readers, they couldn’t download from our Overdrive site to their hand-held reader because we were requiring them to enter their bar code and pin,” McDaniel said.The more basic readers that don’t have “full interactive browsers” but are designed just to download e-books had the difficulties, said Holly Barfield, assistant director for information technology.
