The application of QR code is more and more extensive, which leads to many applications, and QR code business card is also one of the common applications. There should be many friends who will receive other people's business cards in their daily communication. Many business cards are printed with eye-catching QR codes. You can display detailed business card information by scanning the code with QR code scanning tool. This is a two-dimensional code business card.

But many friends don't know that in fact, QR code business cards are divided into hard code business cards and live code business cards.

Hard-coded business cards, that is, writing business card information into two-dimensional code patterns, such as contact phone number, address, etc.

Living code business card is to edit and save business card information on the network, and have the corresponding network address, and then write this network address in the two-dimensional code pattern, so that mobile phone users can scan the code to browse business cards on this network.

The generating principles of two business cards are different, so the characteristics are also different:

Hard-coded business cards are easy to make. You can generate a two-dimensional code pattern by directly using the two-dimensional code generation tool and inputting the contents of the business card, but this two-dimensional code has two shortcomings.

First of all, the amount of information stored is limited. Theoretically, the two-dimensional code pattern is infinite, and the stored data is infinite, but the printed two-dimensional code pattern cannot be infinite. Generally, the QR code printed on paper business cards can store up to 150 characters.

Second, it is difficult to modify hard-coded business cards. Because the hard-coded business card stores the text content of the business card, once it is made, it needs to be modified and the QR code will be regenerated. The generated QR code is different from the previous one, so the previously printed QR code has no use value. For example, after the contact number in the QR code business card is changed, the previously printed business card has no substantive meaning. If these business cards have been distributed, it will be even more difficult.

The advantages and disadvantages of live code business cards are just the opposite of hard code business cards. Making live code business cards is relatively complicated, but it can save unlimited information, even pictures and videos. Moreover, because the content of the live code business card is stored on the network, the QR code only stores the address corresponding to the network business card. As long as the network address remains unchanged, the content of the QR code business card can be changed at will.

Because hard-coded business cards are easy to make, many companies and stores that print business cards use hard-coded business cards to fool customers. Once a customer who has no clue has made such a QR code business card, he has to make it again after modifying the content of the business card.

Hard-coded business cards, many network tools can be made, Baidu search QR code generator, there are many such applications, here is not a simple introduction to the production of hard-coded business cards;

Live code business cards, but also make network tools, Baidu search Q rabbit QR code.
