Smart labels have a UPC barcode in the front with a programmed RFID tag in between the paper layers. RFID label printers can print labels as well as encode RFID chips.

These printers use very high frequency ranging from 13.56 MHz RFID - 900MHz RFID. RFID printers may be connected to a PC using a serial, parallel, USB or Ethernet connection. RFID printers have the advantage of encoding RFID tags and printing them as well as printing barcodes
