Then, a portion of the resist in the antenna region is removed. Then, the antenna region is electroplated with metal material to form an antenna main body. Then, a remaining portion of the resist is removed, and excluding a portion of the metal medium in the antenna region, the other portion of the metal medium is also removed from the substrate. | 02-23-2012 |
20120042377 | PORTABLE DEVICE WITH PASSWORD VERIFICATION FUNCTION AND SYSTEM HAVING THEREOF - A portable device with password verification function includes several input units, a storage unit and a processing unit. The processing unit is electrically connected with the input units and the storage unit. Each of the input units is different from others. Password information is stored in the storage unit.
