Originally, they were fashioned out of iron and bone by the Sumerians and were used to hold clothes together. Later, these pins were also used to hold pages together by threading the needle through their top corner. ref Petroski, Henry, From Pins to Paper Clips , The Evolution of Useful Things, Knopf, New York, 1993, p. 53 ref Many late pins were made of brass, a hard metal. Steel was used later, as it was much stronger, but there was no easy process to keep steel from rusting, so higher quality pins were plated with nickel, but the metal would start to break down and flake off in high humidity, allowing rust to form.

Unreferenced date July 2011 A PIN pad is an electronic device used in a debit card debit or smart card based transaction to input and encrypt the cardholder s personal identification number PIN . PIN pads are normally used with integrated point of sale devices in which an electronic cash register is responsible for taking the sale amount and initiating handling the transaction. The PIN pad is required so that the customer card can be accessed in the case of chip card s and the PIN can be securely entered and encrypted before it is sent upstream to the transaction manager of the switch or the bank. In some cases, with chip cards, the PIN is only transferred from the PIN pad to the chip within the PIN pad itself and it is verified by the chip card. In this case the PIN does not need to be sent to the bank or card scheme for verification. This is known as offline PIN verification . Like some stand alone point of sale devices, PIN pads are equipped with hardware and software security features to ensure that the injected security keys and the PIN are erased if someone tries to tamper with the device. The PIN is encrypted immediately on entry and an encrypted PIN block is created. This encrypted PIN block is erased as soon as it has been sent from the PIN pad to the attached point of sale device and or the chip card. PINs are encrypted using a variety of encryption schemes, the most common being triple DES . PIN pads must be approved to the standards required by the payment card industry to ensure that they provide adequate security at the point of PIN entry and for the PIN encryption process. ISO 9564 is the international standard for PIN management and security. Some well known PIN pad vendors include Hypercom now including Thales e Transactions division , Ingenico now including Sagem , and VeriFone .

The pin feather looks somewhat like a feather shaft. However, unlike a fully developed feather, the pin feather has a blood supply flowing through it.

Pin feathers are therefore sensitive, and some pet birds do not enjoy being handled while moulting for this reason. ref http www.keepingchickensnewsletter.com site pin feathers blood feathers chicken first aid Bleeding Blood Feathers Chicken First Aid ref To stop bleeding from a pin feather, it is necessary to pluck the feather from its base. ref http www.avianweb.com bleeding.html Bleeding Birds Bot generated title ref This can be difficult for a pet bird owner to do on a larger bird, so it is recommended owners have the necessary tools on hand in a first aid kit.

Unreferenced date June 2011 Pin brazing is an easy, Metallurgy metallurgically safe method of making electrical connection s to steel and ductile iron pipe lines as well as other metallic structures, which are to be Cathodic protection cathodically protected or Earthing electrically earthed . The pin brazing technique is based primarily upon Electric arc silver soldering using a specially designed portable pin brazing unit, a hollow brazing pin containing silver solder and Flux metallurgy flux . The brazing process is initiated by depressing a trigger on the brazing gun. This, as with most forms of electrical welding , simply completes a circuit through which a DC current is passed. The pin tip is the point of highest resistance at which point an arc is drawn, melting the solder flux whilst simultaneously heating the lug material and the surface of the structure or pipeline to the required soldering temperature. After approximately 1.5 seconds the circuit is mechanically or electronically broken, the solenoid is de energised and the brazing pin is pushed forward into the molten pool of brazing alloy . The pin tip, brazing alloy, flux and lug cool into a homogenous unit. The pin brazing process is well suited for joints between insulated pipe sections, connection to measuring cables, installation of sacrificial anode s and bonding zinc bracelets to offshore pipelines, due to the ease and speed of installation, high mechanical strength and extremely low resistance. Within a cathodic protection system there are a multitude of connection requirements for anode cables, measuring posts etc, being extremely versatile, the pin brazing system is ideally suited to this. Attachments can be made vertically, horizontally or even overhead. If preferred, threaded pins with nuts can be attached or cable bonded directly onto the pipe by means of a special cable lug which can be crimp joining crimp ed on site or supplied complete as a unique integrally crimped attachment.
