Abstract: A data securing method, a data securing system and a data carrier are provided. The data securing method comprises an encryption procedure for encrypting a data or performing an authentication procedure. The encryption procedure includes the following steps. A first personal identification number is obtained. A first random number is generated. A first key is obtained according to the first personal identification number and the first random number. A first secure checksum is obtained according to the first key. The first random number and part of the first secure checksum are stored. The data is encrypted. The authentication procedure is performed according to the first key.

Abstract: An integrated circuit film comprising a circuit board and a control circuit is provided. The circuit board has an IC-installation part and a contact part and having a first surface and a second surface opposite to the first surface. The contact part comprises a first set of pads and a second set of pads. The first set of pads are located on the first surface for communicating with an electrical communication device. The second set of pads are located on the second surface for communicating with a smart card. The control circuit is mounted on the IC-installation part for communicating with the electrical communication device through one of the first set of pads configured in accordance with a single wire protocol (SWP), a communication protocol.

Abstract: An RFID system comprises an intermediate device that includes a first and second antenna coils connected together in a close loop format. The coils are formed on a flexible substrate that can be folded around a magnetic flux blocker such that one loop is on side of the blocker and the other loop is on the other side of the blocker. The intermediate device can then improve communication between a reader on one side of the blocker and a tag on the other. The coil on the reader side of the blocker can receive RF signals being generated by the reader and convert them to an electrical signal that can be passed to the coil on the tag side of the blockage. The second coil can then generate an RF signal that can be transmitted to the tag.

Abstract: A dual interface SIM card adaptor is described for use with an existing SIM card slot that provides a dual interface electronic information storage card. The dual interface SIM card carrier comprises a flexible printed circuit board, a mini-sized SIM card, a housing to house the mini-sized SIM card, and a cap to affix the mini-sized SIM card in place. The mini-sized SIM card has dimensions that are less than the dimensions for a typical SIM card. The mini-sized SIM card is separable from a carrier that holds the mini-sized SIM card and an antenna. The adaptor is inserted into the SIM card slot in a mobile handset for contact electronic communication, such as wireless telecom, and for contactless electronic communication, such as public transportation, payment and RFID. Contactless communication can be carried out by RFID, Near Field Communication or bar codes.

Abstract: An RFID system comprises an intermediate device that includes a first and second antenna coils connected together in a close loop format. The first coil can be optimized for communication with a reader, while the second coil can be optimized for communication with a tag. Thus, the dimension of the first antenna coil and the second antenna coil can be completely independent of each other. The intermediate device can be configured such that it can change the direction of the transmission from either the interrogator or the tag, thereby improving communication when the interrogator and tag are not inline.
