The QR Code two-dimensional barcodes that are popular around our lives, such as large and small texts posted on the wall or books, packaging, or even the entire book of QR codes, QR (Quick Response) represents rapid response, is In the 1960s, the United States GATF (currently incorporated into the PIA Printing Industry Association) invented the one-dimensional bar code technology that uses only the same thickness and different straight lines to quickly identify, and this ugly bar code has become a storage ware for decades. Identify the simplest and most cost-effective tool for business automation.
Fifty years have passed and a two-dimensional bar code has been invented using small boxes to stack information in boxes. Using the camera phone that everyone has on hand today, you can get a lot of information, up to more than 1,000 English words. A QR Code may also represent a local map. More than two years ago, Taiwan’s high-speed trains had to sell tickets at convenience stores. They discarded tickets that were tracked by tracks previously sold by high-speed railway stations and used QR Code two-dimensional barcodes to identify trackless tickets. Track tickets must pass through the station when entering or exiting the station. The ticket is sent to the magnetic ticket inspection system, and a pass reading confirmation is performed to open the door for passengers to pass. However, in order to use the non-tracked 2D bar code tickets sold outside, it is necessary to establish a photoelectric-reading QR code change system at the gate they are currently entering and leaving the station. Perhaps the QR code ticket machine is relatively inexpensive, and There is no need to add a magnetic stripe that costs about $1.50 behind the ticket, so it is also more advantageous. It is believed that the airport has not seen the boarding pass of the airport still using the magnetic stripe-coded ticket, and has now adopted the QR Code as the identification of the billing data.
Basically, the QR Code is printed by the instrument's optoelectronic equipment. It is not like the original printed on the printed matter. The one-dimensional barcode for humans is an "explicit medium." The QR Code is only for websites that enter the Internet. Name, machine and equipment start identification information, this QR code is used as part of the information transmission, if you use the phone to read a string of text files, a picture or a map, then the QR code is graphic transmission, flat A part of the media, not just information that is not related to printing. In today's era of digital technology, there are black prints, negatives, and plates. These are display media. If you use graphic and textual information or information to spread information, use sophisticated and detailed two-dimensional bar code grids to make large quantities and small quantities. The amount of print dissemination, in place of magnetic strips, disks, USB or other information carriers, once again exploits the advantages of print, will save money on the one hand and easy to read on the other, although the printing industry does not print QR To increase revenue, more people will use printing methods to engage in two-dimensional bar code information dissemination or graphic communication work. It also shows that printing technology has sufficient capacity to store visual information and hidden large amounts of digital information. In the list of university postings, a newspaper can have a name of 15,000 people and the name of the school where the school is located. If you look at it on a computer screen, you may find it ridiculous. The improvement of paper media is the speed of search. Sex!
