Definitions

  • the invention relates to a gaming chip with an integrated electronic data carrier according to the preamble of claim 1 and stations for checking such gaming chips according to claim 15 and a system with such gaming chips and stations according to claim 19 and a method for initializing a gaming chip in gaming systems according to claim 22.
  • a very central problem when using game chips in game systems of any kind is to be able to generally prevent misuse and counterfeiting. And with the increasing spread of gaming facilities, this need to increase security is becoming increasingly important and urgent.
  • other operating functions such as recognizing and checking tokens, exchanging and automatic sorting, etc., should also be able to be carried out more reliably and rationally.
  • EP 436 497 discloses a thermoplastic manufacturing process for round tokens for use in slot machines with or without an integrated transponder.
  • the version with transponder for the contactless transmission of coded information has a transponder with preferably two different types of antennas: an electrostatic antenna and a magnetic antenna - according to US 4,818,855 - read without contact and its value can be checked.
  • this requires a close and precise positioning of the token relative to a reading station in the gaming machine, ie the positioning must be defined to within a few mm.
  • This known chip with transponder requires a relatively complex, multi-part and thus expensive structure with carrier element, plastic ring, various antennas, separate transponder, connections, etc.
  • This structure is moreover only suitable for round game chips for insertion into slot machines (slot machines) and not for Chips of other sizes, shape and application, for example for flat, also rectangular chips for table games and with higher values.
  • a major communication would range of at least a few centimeters instead of just a few mm is required.
  • these known tokens are not really forgery-proof, because there is still the possibility of listening to the communication, copying and producing counterfeit tokens (tape effect). Above all, counterfeit-proof, higher-quality tokens cannot be produced according to this teaching.
  • Another major disadvantage is that this known chip with transponder requires a central computer unit which contains the database for checking all chips.
  • This chip should also be universally applicable in all games that occur in a casino, so that the entire game operation can be carried out with such tokens of the highest level of security against forgery.
  • the token according to the invention must be suitable for all common shapes and for all values, it must be able to be checked from a certain distance and it should enable simple and rational handling in assigned test and sorting stations.
  • the chip should be decentralized from assigned stations, without a necessary connection to a central computer in order to achieve a generally high operating To ensure security, so that the entire game operation is not impaired even in the event of a station failing, and it should be possible to implement both fixed value tokens and tokens with changeable values.
  • a gaming chip according to claim 1.
  • the construction of the chip with a highly integrated data carrier with non-copyable master data means that the chip cannot be copied, ie cannot be copied, in terms of hardware.
  • the initialization of the data carriers by an authorization system ensures that no unauthorized functionality of a token can be achieved.
  • the communication with new initialization data combined with the permanently stored encryption codes ensures that the communication cannot be recorded and copied to another data carrier (tape effect is not possible).
  • the assigned decentralized read / write stations enable safe, autonomous operation without a necessary connection to a central computer. And by being able to write to the data carrier, changes in the value of the token, where necessary, are also possible. Thanks to these properties of the gaming token according to the invention, in connection with the assigned decentralized writing and reading units WR, stations for testing according to claim 15 as well as stations for sorting according to claim 17 can be realized which meet the highest possible security requirements described.
  • the method for initializing a gaming token according to claim 22 is secured by a hierarchical authorization system. provided so that no unauthorized or incorrect MI or gaming chips can be brought into the game system.
  • the dependent claims relate to advantageous developments of the invention, it being possible to achieve particularly long ranges with antennas of relatively large area. Due to the high level of integration on a printed circuit and the use of EEPROM memories and ASIC circuits, particularly compact, efficient and inexpensive tokens can be produced. Particularly efficient communication is achieved by simultaneous energy and information transmission with an RF signal, just as information transmission in one direction by pulse width modulation and in the other direction by load modulation is particularly advantageous. Additional security aspects can be achieved through the use of ever new random numbers and through the integration of checksum controls.
  • entire systems for casinos can be designed by processing different tokens through several assigned autonomous, decentralized writing and reading stations WR, which writing and reading stations are both fully autonomous and additionally functional can be connected to a central computer unit, which enables further additional functions and evaluations.

  • the data memory 12 also contains a part 12.2 which is freely programmable for the desired applications as well as a changeable value storage part 12.3. Thanks to this construction, the gaming chip according to the invention with the data carrier MI can neither be read out nor modified, nor can it be reproduced in terms of hardware.

  • only one HF antenna is required for the chip according to the invention, with which all functions can be carried out; i.e. Receiving energy and information and sending information to the WR writing and reading station. This antenna can therefore be made relatively arbitrarily and above all very large, in principle using the entire token area. This achieves two crucial properties:
  • FIGS. 4a-4f show examples of possible different token shapes: round, rectangular, circular or polygonal tokens and with different antenna arrangements 15. It is always possible to integrate a relatively large-area antenna 15 into the token, which has a high

  • FIG. 5 illustrates the communication 20 between a read and write station WR with a security module 25 and a data carrier MI or a game chip 1.
  • the required electromagnetic RF field energy 20a (for example with a carrier frequency of 13 MHz) is added together with the information 20b sent from the read / write station WR to the data carrier MI.
  • This field energy is collected there by the antenna 15 and used to operate the passive data carrier MI and to send the coded information 20b to the WR.
  • This information transmission is carried out by modulating the carrier frequency in one direction, for example from the read / write station WR to the data carrier MI by pulse modulation and in the opposite direction (from MI to WR) by load modulation.
  • FIG. 6 now illustrates the tap-proof process of this communication between the read and write station WR and a data carrier MI.
  • a data medium MI arrives in the field of a read and write station WR, the process for synchronizing WR and MI begins automatically:

  • the transmitted data is checked by CRC, i.e. Checked by a checksum control, in which user data are linked to master data of the MI data medium. Erroneous data transfers are practically excluded. This is particularly important when value changes are written into a data carrier MI by an authorized read / write station, with newly written data being checked before they become valid.

Categories 32 and 33 can be checked again for the sake of security, after which it can be clarified whether a counterfeit or attempted fraud or a defect in the data carrier MI in the token is involved in order to take appropriate measures. Also important here is the achievable long communication range R (see FIG.

Another important function is performed by an automatic sorting station 40 according to FIG. 8. An unordered amount of supplied tokens 1 of different types and with different values is first isolated (35) as in FIG. 7 and checked by a read and write station WR, whereby any incorrect tokens ( 32, 33) are recorded and separated. The correct valid tokens (31) are then transported to a sorting device 45, where each token is stored in an associated stack 46.1, 46.2, 46.3 according to its previously determined value.

Jeton de jeu (1) présentant un support de données électronique intégré comprenant un processeur (11), une mémoire (12) et une antenne (15) pour la transmission de signaux HF (20), entourés d'une section de boîtier à transparence électromagnétique (2). La mémoire renferme des données de base non modifiables et non copiables (14). Au jeton est associée une section d'écriture et de lecture WR décentralisée autonome, au moyen de laquelle il est possible de lire le support de données MI et d'écrire sur celui-ci. Le support de données MI est initialisé par un système d'autorisation et, pour la communication, à chaque processus d'identification, la station d'enregistrement et de lecture WR fournit de nouvelles données d'initialisation (21), lesquelles sont transmises au support de données MI, où elles sont associées à un code de chiffrement (22), puis retransmises à la station d'enregistrement et de lecture où elles sont décodées et examinées. On obtient ainsi un jeton non falsifiable, utilisable dans tout type d'installation de jeu et garantissant un fonctionnement exempt d'anomalies.
