Summary the RFID electronic tag and bar code label is the same? First of all, conceptually, both are similar, the objective is rapidly and accurately confirm tracking target objects. The main difference is as follows: written information or update the ability of memory. Bar code memory can not be changed. Unlike rf label barcodes, it unique RFID electronic tag and bar code label is the same? First of all, conceptually, both are similar, the objective is rapidly and accurately confirm tracking target objects. The main difference is as follows: written information or update the ability of memory. Bar code memory can not be changed. Unlike rf label barcodes, it unique identifier cannot be copied. Rf tags are not limited to the effect of visual field, because the information is by radio communication, the bar code must be within the field of vision. Due to the low cost of barcode, has a perfect standard system, has been widely used in the whole world, so it has been generally accepted, from the overall, rf technology is only limited within the limited market share. Rfid and bar code is two different techniques, different scope of application, sometimes overlap. Is the biggest difference between the two: bar code is visible technology, scanners work under the guidance of the people, can only receive it vision within the scope of the bar code. Radio frequency identification, by contrast, does not require saw the target, as long as within the scope of the role of the receiver can be read. Bar code itself also has other disadvantages, if the tag is cut, pollution or fall off, the scanner can't identify the target. Bar code can only identify producers and products, and can't identify the specific commodity, posted on all of the same kind of product packaging bar codes are all the same, can't identify which products to expire. Rf tag chip memory and have the detailed information of the product: product name, origin, material, batch, production date, and the effective information such as product. What is the difference between the RFID electronic tag and bar code label:
