First prototype anti-forgery card
The Italian company Legaltag, a company specializing in the development of solutions related to the use of radio transponder technology, presented the first anti-counterfeit identity card prototype. The new proposed identity card uses radio transponder technology to unequivocally link the document to the photograph shown on it in order to make counterfeiting virtually impossible. The demonstrated prototype consists of a traditional identity card in which two are inserted miniaturized radio transponders: one on the photograph of the document holder and one on the document itself. The two transponders contain non-modifiable information, which is recorded by the entity issuing the document. To guarantee the validity of the identity card, the two chips inserted in it must contain a part of common information, which is also stored in a centralized database then used for document control. Since each radio transponder also contains its own unique serial number, the falsification of the impossible identity document since it will never be possible to create a new radio transponder that contains the same information as the original one (chip ID and data related to the owner of the identity card). The transponders used to store information can in fact only be written once, thus ensuring the non-modifiability of the data recorded there. In addition to the anti-forgery features allowed by the adoption of two transponders containing crossed information, the paper prototype identity proposed by Legaltag also offers significant benefits with regard to control procedures. In fact, the collection of documents and the verification of their validity does not require the adoption of readers such as bar codes or similar: the radio technology used in the transponders makes it possible to detect their contents without physical contact between the reader and transponder. When a user near the checkpoint, the scanner in charge of reading the ID card detects the transponder and sends the codes contained in the data management system which can call up on the operator's screen a copy of the personal data of the holder and, obviously, a copy of the photograph. In this way it is extremely easy to check the correspondence between the identity document and the owner. The double transponder protection technology can be applied to identity cards, passports and any other type of documents. The miniaturization of the transponders allows, among other things, the integration also in documents in credit card format, without affecting the characteristics of portability and robustness.
