If you swipe your Penn Card at the printer's Card Reader and you get the error "Unable to read card", your PennCard may need to be replaced. Normal wear and tear can damage the magnetic strip the printer's card reader uses to print your document. To replace your PennCard, go to the PennCard Office:
150 Franklin Building
3451 Walnut Street
Be sure to mention that you are having trouble using your card with the Penn Dental printers.
