Ceramic plate


Ceramic plates (also known as trauma plates) are commonly used as inserts in soft body armor. Most ceramic plates used in the body armor industry can protect against a NIJ level III and IV with a IIIA vest supporting. Ceramic plates are a form of composite armor. Insert plates may also be manufactured from steel or PE.

These plates are often worn by personnel needing protection from rifle fire. In Iraq, the soft armor vest with the ceramic plate helps protect troops from small arms fire up to and including 7.62×63 mm steel rifle bullets.

A ceramic plate is usually slipped into the outer layer of a soft armor vest. There may be two plates, one in the front and one in the back, or one universal plate on either front or back.

The United States Military refer to these ceramic plates as Enhanced Small Arms Protective Inserts (ESAPI).

The approximate weight for one NIJ level III plate is 4 to 8 pounds (1.8-3.6 kg) for the typical size of 10" by 12". There are other types of plates that come in different sizes and offer different levels of protection. For example, the MC-Plate (maximum coverage plate) offers 19% more coverage than a standard ceramic plate.

EMV


EMV is a standard for interoperation of IC cards ("Chip cards") and IC capable POS terminals and ATM's, for authenticating credit and debit card payments. The name EMV comes from the initial letters of Europay, MasterCard and VISA, the three companies which originally cooperated to develop the standard. Europay International SA was absorbed into Mastercard in 2002. JCB (formerly Japan Credit Bureau) joined the organisation in December 2004. IC card systems based on EMV are being phased in across the world, under names such as "IC Credit" and "Chip and PIN". The EMV specification is also the basis of the Chip Authentication Program, where banks give customers hand-held card readers to perform online authenticated transactions.

The EMV standard defines the interaction at the physical, electrical, data and application levels between IC cards and IC card processing devices for financial transactions. Portions of the standard are heavily based on the IC Chip card interface defined in ISO 7816.

The system is not compatible with the original Carte Bancaire smart cards systematically deployed in France since 1992. However, the French Carte Bancaire now also uses the EMV standard.

The most widely known implementations of EMV standard are:

  • VSDC - VISA
  • MChip - MasterCard
  • AEIPS - American Express
  • J Smart - JCB

MasterCard has a Chip Authentication Program (CAP) for secure e-commerce. Its implementation is known as EMV-CAP and supports a number of Modes.
