Barcode
The barcode on RFID cards is considered one of the universal ways of printed personalization. It can encode information of different volume. And to read it, you need to use special readers.
RFID cards with a barcode can be made of different plastics: pearl, gold or transparent. However, a white backing must always be applied below the barcode, as the high contrast of the image makes it easier to read.
The barcode on plastic RFID cards can be used to perform additional functions, such as a loyalty system.
