Problems solved by technology
However, this seemingly "simple" action is very difficult to implement
In the prior art, the film card can only be manually pasted on the surface of the SIM card, and the pasting efficiency is low
At the same time, due to the low accuracy of manual operation, crooked posting often occurs, resulting in waste of resources and time

Embodiment Construction
[0057] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.
[0058] At present, there are three sizes of SIM cards used around the world: the standard card (also known as 2FF card) is 25mm×15mm in size, the Micro SIM card (also called 3FF card) is 12×15mm in size, and the Nano SIM card (also known as 3FF card) is 12×15mm in size. Called 4FF card) is one-third smaller than MicroSIM card and 60% smaller than ordinary SIM card.
[0059] Such as figure 2 and 3 As shown, the front and back schematic diagrams of the film card according to the present invention are shown respectively. The outer contour of the film card 1 shown in the figure...

The invention relates to a card base of a film sticking card, which is provided with a folding line in the middle, and the first part is sequentially provided with a third groove (101) corresponding to the size of a 3FF card and a fourth groove (102) corresponding to the size of a 4FF card along the thickness direction , the film card (1) sticks the sticker layer (11) on the back in the third groove and bonds with the back card (16) through an adhesive, the film card is placed in the third groove, and the back card is placed in the third groove. Among the four grooves, the fourth breakable line (161) is set between the back card and the card base; the second part is sequentially provided with the first groove (201) corresponding to the size of the 2FF card and the first groove (201) corresponding to the size of the 3FF card along the thickness direction. The second groove (202); the film card and the second groove are aligned when the card base is folded in half. The back card is provided with an opening (162), so that the contacts on the back of the film card are exposed from the card base. The film card base of the present invention can realize accurate bonding with SIM cards of different specifications, greatly improves the convenience of use and bonding efficiency, and is suitable for the technical field of mobile payment.
Description
technical field [0001] The invention relates to a card base of a film card, which is suitable for the technical field of mobile payment. Background technique [0002] With the continuous development and popularization of mobile technology, portable devices mainly based on mobile phones are becoming increasingly diversified and enriched in functions. Mobile users are no longer satisfied with a single communication service, and convenient and fast mobile value-added services and mobile payment services are highly sought after. As an innovative product, the SIM film card has brought huge opportunities to the mobile and financial value-added service market with its own advantages. [0003] like figure 1 As shown, the film card is a new type of smart card, also known as "card sticker", which successfully transforms a high-security smart card into a "SIM film". Through this "simple" sticking action, the film card can provide users with more new functions and services without cha...
