Two-dimensional code data format
Qr codes can hold various types of actionable text information. The following describes exactly what information can be stored by QR codes.
1. URL
The most common way of two-dimensional code is to compile the website. It should be noted that the website needs to have a protocol, such as "http://", when compiling, otherwise it will be considered as ordinary text details.
Note that QR codes are more efficient at compiling uppercase letters than lowercase letters, and it is best not to use URL capitalization until you have determined if your server supports generic case.
2. E-mail address
To identify the compiled information as an email address, the format is MailTO:username@gmail.com.
In addition, you can also add the content of the mail, the specific format is MATMSG:TO: username@gmail.com; SUB:Test; BODY:This is a test. ;;
3. Mobile phone number
When compiling the mobile phone number, it is better to add the country number before the mobile phone number. For example, in China, it is +86. For example, TEL:+8613800138000
In addition to compiling mobile phone numbers, you can also compile SMS messages. For example, SMSTO:+8613800138000: Test SMS.
The format of mobile MMS and SMS is the same, specifically: MMSTO:+8613800138000: test MMS;
4. Personal Business cards
You can use the vCard format (http://en.wikipedia.org/wiki/VCard) to use personal name card.
For example, the name is Sun Wukong, the address is Huaguo Mountain, the telephone number is 13800138000, and the email address is wukong@huaguoshan.com. The specific format is as follows:
MECARD:N: The Monkey King; ADR: Huaguo Mountain; TEL:+8613800138000; Email:wukong@huoguoshan.com;;
5. Geographic information
For example, the latitude and longitude information of Google's Seattle office has been compiled. The dimension is 40.71872, 73.98905 west longitude, and the latitude and longitude is accurate to the unit of 100 meters. The specific format is GEO:40.71872,-73.98905,100
