The new $20 bill, which has circulated for little more than a week, is causing some problems with vending machines used in the Penn State community.
The new bill, which features shades of peach and blue and a slightly altered design, has prompted some State College area businesses to make changes. However the federal government has not reported any widespread problems related to the bill, said James Brent, chief of the Office of Currency Production.
The federal government decided to change the look of the bill and add colors for one reason.
"In a word -- counterfeiting," Brent said.
Although counterfeiting has not been on the rise in the country, the use of digital techniques has risen by 40 percent in recent years, he said. The $50 bill is scheduled for change in 2004 and the $100 bill will be changed in 2005, he said.
The Lion Cash machines on campus do not accept the new bills yet, as the ID+ office is waiting for the arrival of a part to be installed, said Cynthia Kellerman, manager of the ID+ office.
Also, the meal point machines will not read the new bills, and signs have been placed at the machines warning students not to use the new bills yet, Kellerman said.
Kellerman could not give a time frame for when the machines would be ready to read the new bills.
"At this point we're just waiting," she said.
Other universities using similar vending systems are experiencing the same problems, she said.
At the State College Post Office, 237 S. Fraser St., all stamp vending machines were modified to accept the new bills, said Terry Fagley, a vending machine technician.
The vending machines, both on and off campus, were all changed prior to the bill's release, Fagley added.
Some downtown businesses have taken measures to educate employees about the new bill.
Jim French, general manager of McLanahan's Downtown Market, 116 S. Allen St., said his cashiers did not undergo any specialized training because of the new bill, but they did receive some general information about its release.
