A retractable, single use syringe (10) comprises a barrel (20), a collar (60) mounted to the barrel, a retraction spring (70), a needle mount (40) located at a needle end (23) of the barrel and a plunger (30). The plunger comprises a first plunger member (31) and a second plunger member (33) that are releasably coupled to co-operatively maintain the retraction spring in an initial compressed state. The second plunger member (33) further comprises a seal (34) to prevent fluid leakage between plunger (30) and barrel (20). After depression of the plunger to deliver the fluid contents of the syringe, the first plunger member (31) engages the needle mount (40) with needle (12) attached thereto and is rotatably uncoupled from the second plunger member (33) to allow decompression of the retraction spring (70), which forces retraction of the first plunger member (31), needle mount (40) and needle (12) engaged therewith. The first plunger member (31) and the collar (60) comprise elements that co-operatively form a disabling means that prevents or at least minimizes the likelihood of subsequent depression or withdrawal of the plunger (30). Also following retraction of the first plunger member (31), the second plunger member (33) and seal (34) remains at the needle end (23) of the barrel (20) thereby preventing refilling and re-use of the syringe.

Methods and devices are provided for making, storing and retrieving electronic representations of payment documents such as payment tickets used for gaming machines. Some implementations sort currency and non-currency payment documents. According to some embodiments, electronic representations are made only of non-currency payment documents. After an electronic representation of a non-currency payment document is made, the payment document is preferably voided. Voided payment documents may be stored in a non-secure storage area, may be automatically disposed of, or may simply be ejected. Some implementations provide devices and methods for resolving payment disputes by reference to stored electronic representations of payment documents. Other embodiments read information from a payment document and make an electronic representation of the payment document without retaining the payment document. Voiding information is transmitted to, e.g., a host device and/or a gaming machine in order to prevent re-use of a payment document.

The information provides a novel internet secure transaction system and a method thereof. A client computer system and an e-currency system running on the client computer system serve as transfer systems and do not participate in interaction with key information; a safe and logic communication link is built between a service terminal and information safety equipment; and key information does not appear in the client computer system and the e-currency system in the clear form so that a user key can not be intercepted and utilized repeatedly by an attacker. In order to achieve the purpose of building the safe and logic communication link, the dynamic key technology is used in the invention, that is, in the process of internet transaction, keys used each time are different. Each time the internet transaction is conducted, the bank service terminal generates two new symmetrical keys which are encrypted and then transmitted to the information safety equipment. The information safety equipment decrypts the encrypted keys to obtain the key so as to conduct the encryption communication with the service terminal. Even if the key is intercepted by the attacker, the key can not be used next time, because the keys used each time are different.

A single-use auto-disable syringe device of reduced size utilizes a locking element to prevent re-use of the syringe by locking the plunger rod with respect to the barrel upon completion of an injection stroke. The plunger rod includes a plurality of teeth comprising distally facing shoulders provided on a majority of the length of an elongate portion of the plunger rod and a breakable section configured to break upon the application of excessive axial or torsional force. The breakable section is preferably provided at a distal end of the plunger rod so that a proximal end of the locking element engages the syringe barrel and plunger rod at a position more proximal than the breakable section. In this way, the locking element resists some of the force that would otherwise be applied to the breakable section if the plunger rod were twisted. The plunger rod also includes an intermediate tooth provided on a distal-most tooth to prevent the user from repeatedly drawing in doses too small to activate the safety mechanism.
