A system and method for enhancing functional interoperability of contactless payment devices that are used for conducting electronic payment transactions between consumers and merchants. The contactless payment devices include RFID-embedded cards issued to consumers and proximity coupling devices such as RFID-enabled readers deployed by merchants. The system and method involve use of a reference card and a reference reader to establish acceptable specifications for issued cards and deployed readers, respectively. The reference card and reference reader are cross-calibrated to link the operational specifications for the cards and the readers. A suitable selection of overlapping specification ranges or tolerances for proper card and reader functions, the enhances the interoperability of the issued cards with a deployed reader, and also the interoperability of deployed readers with an issued card.

A game method of play that combines features of the game of poker with features from a variety of competitive sporting events. A deck of 56 cards is utilized containing four suits and fourteen rank cards for each suit (the rank of “1” for each suit is added to a standard deck of 52 cards). Indicated on the face of each card is a scoring value associated with a particular sporting event competition. The players carry out the play of the game in a manner similar to that of poker, playing for a poker outcome using the poker values, as well as a scoring outcome using the sports scoring indicia on the cards accumulated in the player's hand. Depending on the embodiment of the game being played, winning can occur in three ways: by holding the best poker hand value; by holding the best scoring hand value; or by having the best cumulative scoring outcome over multiple hands. In this manner, players bet during the play of the game on both the anticipated value of their poker hand and the anticipated value of the sporting event scoring values reflected on the cards they retain. Score cards and rank value reference cards facilitate the play of the game and the process of betting on the outcome.

The invention discloses a method for rapidly determining dissolved oxygen in water. The method is characterized by using a water sampler, a test tube or colorimetric tube, reagents, a dropper and a dissolved oxygen reference card, wherein the water sampler comprises a soft bottle with a rubber stopper; the rubber stopper is provided with an air tube and a water tube; the air tube and the water tube are respectively provided with a valve card; the reagents include anhydrous manganese sulfate and alkaline potassium iodide; and the dissolved oxygen reference card is a standard color gradation card made according to the colors of the precipitates produced by reaction between the standard water sample containing different dissolved oxygen and the reagents.

The card game is played using two decks of cards per each hand, with the dealer dealing out two groups of cards face down from one deck and a single face up reference card from the second deck. The dealer then turns up each of the cards sequentially from the two groups of the first deck, with the object being to attain an exact match between any or the cards of the two groups, and the reference card. Optionally, players may wager upon the likelihood of the occurrence of a specific mismatch.

A communication system includes at least one contactless card configured to transmit an encoded identifier; and a reader configured to receive the encoded identifier and compare the received encoded identifier with an encoded reference card identifier, wherein the reader requests data from the contactless card if the encoded identifier matches the encoded reference card identifier.

A reagent is provided for the detection of an exotoxin protein produced by a beta-hemolytic streptococcus bacteria suspected of being present in a host biological fluid collected from a subject. An enzyme inhibitor is present to inhibit rogue protein modification of the substrate to prevent a false positive result of the color change. A kit is provided that is readily usable by an untrained user and merely requires that an element of the kit be contacted with a biological sample and thereafter no further actions are required by the user before a discernable color change is observed with visible or UV light and a positive / negative results reference card.

A method of determining a time to replace developing solutions in a printer includes providing a reference card including sample patches of standard colors for predetermined colors of the developing solutions, sample patches of test colors into which the standard colors change due to contamination, and standard color differences DeltaE* calculated from standard color values Es* corresponding to the respective standard colors and measured standard contamination values Ec* corresponding to the respective test colors; inputting information about test patches for the predetermined colors into the printer and printing the test patches; and comparing the sample patches with the test patches to determine whether to replace the developing solutions. Since the reference card is provided together with a printer including information about test patches, a user can easily determine a time to replace a developing solution.
