The present disclosure relates to a surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member configured to releasably receive a firing assembly and a single use loading unit. A lockout structure prevents insertion of the single use loading unit into the channel member after the firing assembly is mounted to the cartridge receiving half-section. Alternatively, the lockout structure prevents full insertion of the firing assembly into the cartridge receiving half-section, if the single use loading unit is not engaged with the firing assembly.

An apparatus for detection and quantitation of an electrochemically-detect- able analyte, such as glucose, in blood or interstitial fluid includes a meter unit, a lancet and an electrochemical sensor. Of these components, the meter is preferably reusable, while the lancet and the electrochemical sensor are preferably incorporated in assemblies intended for single-use. The meter unit has a housing, within which a lancet is engaged with a mechanism for moving then lancet; a connector disposed within the housing for engaging an electrochemical sensor specific for the analyte and transmitting a signal indicative of the amount of analyte, and a display operatively-associated with a connector for displaying the amount of the analyte to user. The electrochemical sensor is adapted for detection of a particular analyte. In addition, the electrochemical sensor has an absorptive member for uptake of a sample of blood or interstitial fluid. In one version, the lancet moves from a initial position to a piercing position in which skin of the user is pierced and optionally back to a retracted position. The electrochemical sensor is disposed such that the absorptive member takes up a sample from the pierced skin of the user when it is pierced by the lancet without movement of the apparatus. In an alternative version, the lancet is a hollow cannula through which blood or interstitial fluid is transported from the puncture site to an absorbent portion of the electrochemical sensor. In either version, the apparatus provides single-step operation in which sample acquisition and analysis occur as a result of the single action of pressing the apparatus against the users skin.

Embodiments of the invention introduce efficient methods for securely generating a cryptogram by a user device, and validating the cryptogram by a server computer. In some embodiments, a secure communication can be conducted whereby a user device provides a cryptogram without requiring the user device to persistently store an encryption key or other sensitive data used to generate the cryptogram. For example, the user device and server computer can mutually authenticate and establish a shared secret. Using the shared secret, the server computer can derive a session key and transmit key derivation parameters encrypted using the session key to the user device. The user device can also derive the session key using the shared secret, decrypt the encrypted key derivation parameters, and store the key derivation parameters. Key derivation parameters and the shared secret can be used to generate a single use cryptogram key. The cryptogram key can be used to generate a cryptogram for conducting secure communications.

Interengaging sets of contacts on the handpiece and battery are adapted to become lockingly and conductively interengaged upon rotation of the battery pack relative to the handpiece, in a manner that rapidly achieves correct alignment of the parts and also ensures stable mechanical attachment and support during the surgical procedure.

A conventional looking payment card comprises a plastic card with a legacy card reader compatible magnetic stripe for dynamic user account data. Internal to the plastic card, and behind the magnetic stripe, a number of fixed-position magnetic write heads allow the user account data to be modified autonomously. Electronics within the card are pre-loaded with many unique numbers that are selected for one-time use in financial transactions. A payment processing center keeps track of the unique numbers used, and knows which numbers to expect in future transactions. It will not authorize transaction requests if the unique number read during a magnetic card swipe is not as expected. A card-swipe detector embedded in the plastic card detects each use in a scanner, so changes can be made to the data bits sent to the write heads.

A credit card system is provided which has the added feature of providing additional limited use credit card numbers and / or cards. These numbers and / or cards can be used for a single or limited use transaction, thereby reducing the potential for fraudulent reuse of these numbers and / or cards. The credit card system finds application to “card remote” transactions such as by phone or Internet. Additionally, when a single use or limited use credit card is used for “card present” transactions, so called “skimming” fraud is eliminated. Various other features enhance the credit card system, which will allow secure trade without the use of elaborate encryption techniques. Methods for limiting, distributing and using a limited use card number, controlling the validity of a limited use credit card number, conducting a limited use credit card number transaction and providing remote access devices for accessing a limited use credit card number are also provided.
