Nfc qr code label for preventing forgery and falsification and method for producing nfc qr code label

An NFC QR code label manufacturing method for printing a rectenna, a ring oscillator, and a light-emitting QR code through an R2R or S2S gravure printing method, the manufacturing method comprising the steps of:

• printing an antenna pattern included in the rectenna on a flexible substrate;
• printing a lower electrode pattern including a rectenna lower electrode, a ring oscillator lower electrode, and a QR code lower electrode on the flexible substrate;
• printing a QR code pattern on the QR code lower electrode using a non-conductive ink;
• printing a transparent electrode continuously covering the entire QR code pattern;
• and
• printing an upper electrode pattern including a rectenna upper electrode and a ring oscillator upper electrode.

• laminating an electrophoretic sheet continuously covering the entire area of the QR code pattern while facing the lower electrode pattern on which the QR code pattern is formed;
• and
• printing an upper electrode pattern including a rectenna upper electrode and a ring oscillator upper electrode.
