Patent number: 9396427Abstract: A removable tray integrated smart card and a mobile terminal adopting the same are provided. The smart card includes: a case configured to be removable into/from a smart card insertion slot of a mobile terminal; and a secure element provided in the case, wherein the case is removable into/from the smart card insertion slot without being placed on a tray. Accordingly, the smart card such as a USIM-card can be inserted into the mobile terminal without using the tray. In addition, since the size of the smart card increases as the smart card is unified with the tray, many high performance antennas and wireless modules can be inserted into the smart card and thus wireless communication performance of the smart card can be enhanced.Type: GrantFiled: December 18, 2012Date of Patent: July 19, 2016Assignee: SK HOLDINGS CO., LTD.Inventor: Zang Hee Cho
