QUICK RESPONSE CODE FUNCTION COMBINED WITH THE SHELF LIFE PROGRESS INDICATOR AND SHELF LIFE PROGRESS DISPLAY METHOD USING THE SAME

摘要

The present invention relates to a quick response code function-combined expiry date indicator and an expiry date display method using the same. The indicator includes a QR code to store information on a relevant product, which is prepared on one side of the packing material to contain fresh products or frozen products; and an expiry date display tag to show an expiry date of a relevant product by contacting an expiry date display diffusing agent, which starts being dispersed when a product is released by being linked with a QR code. The display method includes the steps of: packing fresh products or frozen products; preparing a QR code; preparing an expiry date display tag; starting diffusion of an expiry date display agent; detecting a product on a normal distribution by recognizing a color printed in advance which is printed on the side of a diffusion start display window; and detecting an expiry date over by recognizing a color printed in advance which appears on the side of an expired distribution period display window. Accordingly, products which are in best quality can be provided to consumers by displaying the expiry date of a relevant product.
