EMV is a technical standard for smart payment cards and for payment terminals and automated teller machines that can accept them.

EMV cards are smart cards (also called chip cards or IC cards) that store their data on integrated circuits in addition to magnetic stripes (for backward compatibility).

These include cards that must be physically inserted (or "dipped") into a reader and contactless cards that can be read over a short distance using radio-frequency identification (RFID) technology.

Payment cards that comply with the EMV standard are often called Chip and PIN or Chip and Signature cards, depending on the authentication methods employed by the card issuer.

A debit card (also known as a bank card or check card) is a plastic payment card that can be used instead of cash when making purchases.

It is similar to a credit card, but unlike a credit card, the money comes directly from the user's bank account when performing a transaction.

A consumer price index (CPI) measures changes in the price level of market basket of consumer goods and services purchased by households.

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

The tags contain electronically stored information.

Passive tags collect energy from a nearby RFID reader's interrogating radio waves.

Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader.

Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object.

RFID is one method for Automatic Identification and Data Capture (AIDC).

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.

Metals are generally malleable—that is, they can be hammered or pressed permanently out of shape without breaking or cracking—as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire).

About 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids.

Some elements appear in both metallic and non-metallic forms.
