摘要:
Information can be obtained from a document having printed electronic circuits by using an electronic verification machine that determines the electrical characteristics or signatures of the circuits printed on the document. The electronic verification machine electronically couples with the circuit and applies an excitation signal such as an AC signal having a predetermined frequency to the circuit. A detection circuit in the electronic verification machine then generates a detection signal in response to the excitation signal which represents the characteristics of the circuit printed on the document. The electronic verification machine can also be used to stigmatize the document by applying a signal to the electronic circuits having sufficient strength to alter the electronic circuit.
摘要:
A method for forming a document includes the steps of (1) selecting a marking medium that has a pre-determined machine-readable characteristic, and (2) selecting a document substrate that is compatible with the pre-determined machine-readable characteristic of the selected marking medium. An information symbol is secured to the selected document substrate. A security layer which includes the selected marking medium is also affixed to the document substrate so that the security layer is in at least partial register with the information symbol. The method can further include the step of affixing a blocking layer to the document substrate in at least partial register with the information symbol. The blocking layer can be affixed to the document substrate so that blocking layer is intermediate the information symbol and the security layer or so that the security layer is intermediate the information symbol and the blocking layer. Inks that can be printed with conventional printing methods, such as intaglio printing, screen printing, relief printing, planographic printing, letterpress printing, and flexographic printing, are especially useful as any of the selected marking media. The ink used is chosen for a particular machine-readable characteristic such as dry-state conductance, fluorescence, optical density, reflectance, and scattering. For example, an ink which has a known, measurable conductance in a dry-state can be used to print conductive layers on the document which serve as security layers.
摘要:
Described is a player activated game system, particularly adapted for playing instant lottery type games, that includes a game device having a computer containing at least one game, an electronic display and a card interface adapted to receive a game card having data that represents a particular game outcome such that connection of the card to the interface can result the game being played by the device with the particular outcome displayed on the display. Also described are lottery tickets or game cards that are adapted use with the game devices along with methods of manufacturing the game cards.
摘要:
An electron game machine is provided that may be used in association with standard or special type lottery tickets to enhance a lottery players game experience. The machine may be configure for single or plural play options and may be recharged for reuse. Game play data may be entered manually or automatically. Game machines may be manufactured as generic devices and programmed with game specific information as needed.
摘要:
Described are a number of mechanisms that can reduce transaction costs and increase the economic viability of a number of products. Included is a combination instant lottery ticket and debit card that makes it possible to issue prepaid debit cards having a relatively low monetary value. Also included is a combination on-line ticket/receipt and debit card that can automate the prize paying process, simplifying the retailer's responsibilities while reducing the potential for fraud. Various cash flow and authentication techniques such as age and location verification, nano payment methods and spam filters based on these mechanisms are also described. In addition, instant lottery tickets, and in particular, losing tickets can be provided with a small residual value by placing account information on the ticket. In another version, a lottery ticket can be combined with a payment card that operates as a closed payment system whereby the payment card can only be used with a specified vendor.
摘要:
A lottery game played on an electronic game machine using a pre-printed lottery ticket is disclosed. The lottery ticket is embedded with game and prize information that can be read by the game machine. After inserting the lottery ticket into the game machine, the player may play a game using the game machine based upon the information on the lottery ticket. If the player is a winner, an award is given to the player. The player can redeem the award for cash with the lottery authority.
摘要:
A method of embedding an optical signature in a document and document produced therefrom. The optical signature uses an invisible optical pattern or covering that can reflect light in non-visible wavelengths, such as light in infrared, or fluoresces when exposed to a particular wavelength of light, such as ultra-violet light. The invisible optical pattern can be a covering over another optical pattern, or a base pattern upon which a second optical pattern is embedded.

摘要:
A method of embedding an optical signature in a document and document produced therefrom. The optical signature is an optical pattern generated from a known value, such as a mathematical, geometric, trigonometric, size, phase, and the like, and the same value can be generated from examination of a document having the embedded optical pattern. The document can be validated, authenticated, or the determination of a valid copy of an original document with the embedded optical signature made through comparison of the known value and the value generated from the optical pattern on the document. The optical pattern can also be generated from other identification codes on the document.
