Abstract: TITLE : INFORMATION MANAGEMENT SYSTEM AND DEVICEThe present invention relates to an information management system, and in particular to a portable information management device. The device includes ahousing having a first surface and a second surface, said first and second surfaces securely enclosing electronic componentry of the device, wherein the electronic componentry includes: a data storage device for storing information about a person or asset; and a processor for transferring the information from the data storage device to an external device via a communicaton means, whereinthe communication means includes: an antenna to allow contactless transfer of the information; and an input/output interface to allow transfer of the information via physical means, as shown in Figure 1. TITLE OF INVENTION WEi TAG1 October 20101. Backgrouns to inventionA "dog tag" is e informal name for the identification tags worn by militarypersonnel, becaus of their resemblance to actual identity dog tag that dog owners place around he necks of their dogs.In the military, such " g tags" are primarily used for the identification of dead and/or wounded military•rsonnel and these tags provide the essential yet basic medical information to ai. in the treatment of the wearer (such as his or her blood type and history of mo.. lations).Fig 1 - A metallic dog for US soldier"Dog tags" are usually fabricated from a co osion-resistant metal or alloy such as aluminum or stainless steel, however, • ring war-time these have been known to be made from all types of metals avail. sle at the time.In the event the military personnel has a spe 'fic medical condition which requires special attention during medical treatment, an additional red tag with the pertinent information is issued and worn together ith the "dog tag".It is requirement that all military personnel have to wea their issued "dog tag" and additional red tag (if applicable) at all times when they re in the field.Sometimes such "dog tags" may contain two copies of the sa e information and they can be designed to break off easily into two pieces to allo half of the said "dog tag" to be collected for notification purposes whilst the or er half remains with the body should the battlefield conditions disallow the sualty to be immediately recovered.Typically, two identical "dog tag" ("Tag") are issued to each military ersonnel. One Tag is worn on a long chain around the neck; the second Tag on a much smaller chain attached to the first long chain. In the event the wearer H killed during combat, the second Tag is collected and the first Tag remains wit the body. TITLE OF INVENTION : WEI TAGFr rec is neThe tray tional metallic Tag is unable to hold large amounts of critical medical informatio /data due to its limited size and surface area.Another prob m posed by the use of a traditional metallic Tag is in the scenariowhere a soldi gets killed in the field during combat, normally one of the 2traditional metal 'c Tag is put into the deceased mouth. However, the difficulty ead body stiffens and the nerve around the mouth of the asily opened to retrieve the said Tag. This makes the task rose difficult as the metallic Tag must be retrieved toTo overcome these limitati ns, the Applicant has conceptualized the making and design of an Electronic Tag ich has unique capabilities and functionalities:a contact and contact' s read and write feature for real time, easy retrieval of critical medica information/data from the Electronic Tag and identification purposes (*);a rewritable feature which allo s for continued easy management of the information/data contained in the Electronic Tag;a data storage capacity which is not vailabie in the traditional Tag;capacity to store large amounts o information/data in one device (Electronic Tag), replacing the redundan y of having 2 traditional metallic Tags.(*) To address the identification problem, the Electra 't Tag allows for a contactless reading by simply placing the contactless reader over t mouth of the deceased, the identification of the party can be easily read and the need o pry open the mouth of the deceased will no longer be necessary.Design of the Electronic Tag ("WEI Tag"): To design the architecture of the Electronic Tag, the App integrated and applied multi-discipline technologies. Firstly, it various circuits, then integrate each one into the other by usi electronics circuits. Below is a simplified diagram of the Electronic Ta contact and contactless interface are Clearly shown. TITLE OP INVENTION : WEI TAG Electronic Tag Components 2. Contactless ReadinWe had applied the Near ield Communication (NFC) to tap on its unique over the air communication cap bilities. Secured "over the air" protocol allows for data confidentiality while its eer to peer data exchange feature can be further exploited to offer new operat .nal experiences. The contactless read range is designed to be the same as NE maximum read range of 3cm. The contactless interface conforms to ISO 14443 tandard and operates at 13.56MHz. To avoid the need to do prolong contactles reading (i.e. long reading time), the data storage for the contactless reading kept small and capped at the range of 20Kbits to 30Kbits.When the Electronic Tag is worn around he neck and loosely hung around the front of the wearer's chest, the said tag as a tendency to flip over front and back during movement. As such, there is need for contactless reading from either side of the Electronic Tag.To achieve this contactless reading from eithe side of the said tag, different layout designs of the PCB were fabricated and tes ed. The current design allows for a reading range of 3cm from either and both sid of the tag. Different antenna pattern designs to mee read range requirements TITLE OF INVENTION : WEI TAG ntact ReadingWe ad designed the embedded CPU circuits to incorporate large storage capac y NAND flash memory chip to provide a sufficiently large storage capacity to store all relevant medical records needed by wearer, The storage capacity can be scale. in multiples of Gigabites depending on the storage needs. Currently, the protot e tag incorporates 128 Mbytes of storage space.CPU is also connected so that it is able to assess the data stored rea of the contactless section too. When the contact sector of ered up (by slotting the tag into the socket of the reader), the interface technique allows the embedded CPU to exchange ontactless data storage sector and contact data storage When the contact secto is not powered up, the design of the electronic circuit still allows the contactles sector to operate independently, without disruption. Without electrical power, th Electronic Tag functions as a passive secured RFID tag.To further enhance the design o the Electronic Tag, the embedded CPU sector is also designed to handle and m nage information assurance (IA) to ensure confidentiality of data stored within e Electronic Tag.Visual ReadingThe Electronic Tag housing unit is mad of plastic materials friendly to the human skin. The housing unit surface is de ned to incorporate information like the wearer's name, grouping, etc. This can e easily etched on the surface by laser etching/engraving.In summary the 3-in-1 design of the Electron Tag permits visual reading, contact and contactless identification as well as t e derivation of a new unique electronic platform.The working prototype of the Electronic Tag is as s own below together with artist impression of a version of a WET Tag reader.

Assessment of echnologies used by others (off the shelf products)Below is a table sho ng the technologies applied in WET Tag architecture where some components of t se technologies are found in other products in the marketplace. However, none the available products contain all of the technologiescomprised in the WET g. There is therefore no identical or closely similarproduct resembling the W Tag architecture available. Most of the products may contain a USB thumb drive a contactless chip card, but these are all standalone applications and have limited nctionality to offer to the user.The Applicant anticipate future enhancements to the c rrent prototype was developed which could include:miniaturization of the Tag to reduce its size and weight;the hardening of the exterior unit using materials su as ceramic that can withstand higher temperatures of 200°C or more.In addition, the application of the WET electronic tag can be ex nded to be applied to:- Secure authentication tokenSecured miniature virtual computing platform6
