Credit Card Scanners
Many retail businesses and restaurants use credit card scanners to get instant
approval of credit card purchases. The system allows your credit card
scanners to share the lines in your system (as shown in Figure 4-4). You can
install a credit card scanner on an extension by itself, or combine it with a
system phone or a standard phone on the same extension. (See “Combination
Extensions” in Appendix C for information on connecting two devices on one
extension.)
