Warranty card. Warranty card is the guarantee of product quality and the "identity card" of the product. Only digital cameras imported or produced through normal channels have warranty cards. If it is smuggling, it is also commonly known as "parallel imports", but parallel imports do not have warranty cards. The warranty card will generally indicate the camera model, camera number (each digital camera has only one number, the body number and the warranty card should be in one-to-one correspondence, and the number of the digital camera can be inquired by telephone), as well as the purchase time, warranty time, warranty point and telephone number. The most important thing is to have the signature or seal of the manufacturer. If you are not at ease when you buy it, you can take the product to the repair shop for verification, or call to ask if you have the serial number of the machine.
At the same time, the warranty card is the basic certificate of maintenance, and the general maintenance needs to issue the warranty card and invoice at the same time to enjoy the warranty service.
