1.5 QR Code

QR Code was invented in 1994 by Denso, one of major Toyota group companies, and approved as ISO international standard (ISO/IEC18004) in June 2000. This 2-dimentional symbol was initially intended for use in production control of automotive parts, but it has become widespread in other fields. Now QR Code is seen and used everyday everywhere in Japan for the following reasons:

  • Several characteristics superior to linear bar codes: much higher data density, support Kanji character, etc.
  • It can be used by anybody free of charge as Denso has released the patent into the public domain
  • Data structure standard is not prerequisite for current usages
  • Most mobile phones in Japan equipped with cameras that enable reading of QR Codes can access Internet addresses automatically by simply reading a URL encoded in the QR Code

In this section, accessing to the internet by mobile phone, the most popular usage of QR Code, is described in 1.5.1 and other various applications in 1.5.2. The ASN delivery system where GS1 Identification keys are used with QR Code is described in 1.5.3.
QR Code has been adopted as a standard symbology for direct part marking on surgical instruments in Japan as well. For details, see 4.1.2-3) "GS1 System for Surgical Instruments".

1.5.1 Application to Mobile Phones

The following section explains typical solutions enabled by scanning QR Codes with camera-equipped cell phones. Specific cases studies are also explained.

(1) Typical solutions
A. Access mobile websites with QR Code
Encode URLs of mobile websites into QR Codes and print them on products or sales promotion tools. Then users can access those websites by simply reading the QR Codes with their camera phone. This type of advertising is more effective than using flyers and pamphlets.

B. Access product order websites with QR Code
Encode product order URLs of mobile websites into QR Codes and print them in magazine ads or pamphlets. Then users simply scan a QR Code to access the product ordering page. Users can place orders anywhere and at anytime. QR Codes allow sellers to take full advantage of more business opportunities.

C. Enter contact data into cell phone address book with QR Code
Encode contact information, such as name, phone No., and e-mail address, into a QR Code and print it on their business cards. Contacts who receive their cards can enter the data into their address books by simple cell phone scanning operations. This type of business card will be welcomed by business people who can save time to enter contact information.

(2) Case studies
A. Product information (A food manufacturer)

  • Problem: There was no convenient way to convey information to product purchasers and no handy tool to easily advertise product values in the most effective manner.
  • Solution: QR Codes on product packaging
  • Effect: QR Codes make Web access easy. Customers can download information such as video taped recipes anytime and anywhere they need to.

B. Searching for tour packages and making travel bookings (A travel agent)

  • Problem: Counter attendants can accept travel bookings only for a limited time range. On the other hand, few people make travel bookings at websites that require use of PC.
  • Solution: QR Codes on travel brochures
  • Effect: Information is available 24 hours a day. Cell phones are easier to operate than personal computers. QR Codes create more new business opportunities.

C. Bus location information service (a bus company)

  • Problem: There was a need to improve information services for passengers waiting at bus stops such as the present location or delay and to promote use of buses
  • Solution: Display QR Codes at 3,000 bus stops so that passengers can check on the present status of their bus using their cell phone.
  • Effect: Use of QR Codes has increased customer satisfaction by making real time bus operation information avairable.

D. Restaurant information (a restaurant search site)
(Japanese) http://www.gnavi.co.jp/ (English) http://www.gnavi.co.jp/en/
This restaurant search site in Japanese displays a QR Code for each restaurant. By scanning the QR Code from their PC monitor, users can easily access the restaurant's mobile website.

1.5.2 Delivery System with QR Code

In order to enhance distribution efficiency by using ASN (Advanced Ship Notice) and SCM (Shipping Carton Marking) labels, GS1 Japan drew up guidelines for the system using ASN and SCM in cooperation with the Japan Chain Store Association (JCA) in 1993. However, in the actual transactions, many SME business partners face difficulties in the use of ASN.
In case of department stores who handle many products, they have a number of small and medium sized trade partners that do not employ ASN systems and were forced to spend long time for receiving inspection.
To cope with this situation, in 2001, we prepared guidelines using QR Code on SCM labels and invoices in cooperation with the Japan Department Stores Association as well as the apparel and cosmetic industries, which are major business partners of department stores.
Currently, the apparel, cosmetic, and accessories and bedding industries adopt the system, and the number of major department stores adopting the system has reached almost 10. The system has already achieved a considerable amount as a delivery system targeting SMEs.

1.5.3 Various Other Applications of QR Code
The QR Code presently finds a wide range of applications in various industries.
1. Prescription for dispensing pharmacies
A new service has started in which prescription data is encoded into QR Codes and printed on prescriptions. The specifications for recording the data are standardized by the Japanese Association of Healthcare Information System Industry (JAHIS). In this service, users read prescription data with a scanner, which enters patient and prescription data quickly and accurately into the computer, preventing input errors and alterations of prescriptions. Because the service reduces time required for data input, waiting time becomes shorter for patients while pharmacists can spend longer time giving instructions on dosage and administration.
Data to be encoded include information on the medical institution, diagnosis and treatment department, physician's name, patient's name, health insurance information, and drug information. Coded information complies with the data exchange standard of HL7 with which GS1 concludes a Memorandum of Understanding for collaboration.
2. Standardization at the Japan Association of Medical Equipment Industries
GTIN and serial numbers are coded into QR Code and directly marked on steel surgical instruments.
(For more details, refer to 4.1.2-3.)
3. Test System for Blood Specimens
Medical laboratories analyze and test medical specimens such as blood as commissioned by medical institutions. These specimens must be accurately managed and identified individually because a great number of specimens are handled every day for individual hospitals, and test types.
At some laboratories QR Code labels are automatically printed, marked and attached by labeling equipment. Data include acceptance date, medical institution name (in Japanese kanji characters), analysis/test item code, test site code, and identification number.
4. Sales Management of Glasses and Contact Lenses
QR Codes are used for the sales management of contact lenses and glasses. For a contact lens, the product code, product name, degree of correction, base curve, and other information are encoded into a QR Code of about 8 square mm size. The code is printed on the lens container, and the information is used for point-of-sales or inventory management.
5. Visitor Management System
At various exhibitions, seminars, and receptions QR Codes on the ID badges of visitors and/or event staff are scanned when they enter and exit the venue, and used for various purposes such as on-site security management, marketing management, and customer management. For example, QR Code was used in the Expo 2005 Aichi Japan for the staff/vehicle entry control.
6. Passenger flight information carrier for ticket-less boarding
Many airline companies are introducing a ticket-less boarding service that allows domestic flight passengers to go on board without check-in. In Japan, passengers can choose QR Code as an information carrier. The ticket-less boarding system varies with airlines, but a customer who purchased a ticket, reserved a seat, and paid for it online can usually choose QR Code as a medium to receive flight reservation information. The QR Code is then sent to the customer's cell phone or PC. A boarding pass is issued when the code is scanned by the reader at the security check counter or the boarding gate. This service is advantageous to customers who no longer have to check in. It is also advantageous to airline companies which no longer have to issue paper tickets. A Japanese airline company plans to completely switch to the electronic ticket system by the end of 2007.
Recently, the International Air Transport Association (IATA) announced a global standard that allows multiple 2D symbols including QR Code for use in mobile phone check-in system, which will be implemented by 2010.
7. Backup of vehicle inspection certificate information
In Japan, QR Code is marked on the vehicle inspection certificate, which certifies each vehicle registered and inspected to meet the requirements. While the certificate is kept by the car owner, a vehicle inspection sticker is attached to the car itself. When the sticker needs to be reissued, the QR Code on the certificate is read to reduce paperwork.
8. Shipment Management System for Clothing
An apparel manufacturer prints QR Codes displaying the shipment destination, GTIN, color, and size on the shipping instructions and utilizes them for shipment management. Some of the information encoded in QR Codes are written in Japanese kanji characters or and/or phonetic characters.
9. Identification of Building Sites for Sale
A local organization engaged in urban land readjustment and redevelopment sticks ceramic tiles with QR Codes carrying the location information to land survey markers to match the surveying drawings. These QR Codes on the site enable correct and prompt identification of land and buildings and improves work processes.
