This device captures Caller ID and displays on your POS the customer’s name and phone number. The POS then auto-populates their other information such as delivery address and past order history. Units are available in 2, 4, and 8 line models with either Serial/USB or Ethernet connection. This device is compatible with the LineSkip POS. If you are not using the LineSkip POS, please check with your POS provider prior purchasing.
