Abstract: Tamper-proofing and secure identity validation techniques in a transaction processing system and secure electronic payment techniques are disclosed. A tamper-proof transaction processing device is provided and comprises at least two different strength adhesives to secure parts of the device together and a housing comprising at least a first and second protective layer. An electronic component comprising a secure element chip storing unique information relating to the chip is located between the first and second protective layer in the housing. In another aspect, a transaction processing system includes a payment instrument that is configured to approve only negative value and/or zero value transaction requests. Another aspect provides an identity card checking system and method where the identity card is brought into proximity of a data processing device and identity information is displayed on the screen of the data processing device for the period of time while the card is in proximity.

Abstract: Nucleotides comprising a reporter moiety and a polymerase enzyme blocking moiety in which the reporter moiety does not also act as a polymerase enzyme blocking moiety are described. Also described are compounds of Formula (I): wherein W is a phosphate group, B is a base, Y is a linker comprising an enzyme-cleavable group, R2 is a reporter moiety, R3 is selected from H or OH, Z and Z? are selected from H, OH, or a group X—R1, wherein X is a linker comprising an enzyme-cleavable group and R1 is a polymerase enzyme blocking group, provided that at least one of Z and Z? is X—R1.
