What Is Chip and PIN?

Chip and PIN meaning: how chip plus PIN works, chip and PIN vs chip and signature vs contactless, and what Visa rules mean for a business terminal.

Article summary

TL;DR

Chip and PIN is a way to pay in a store: the customer inserts a card with an EMV chip into the terminal and types a secret PIN on the keypad. The chip proves the card is genuine, and the PIN proves the person is the cardholder. In the UK, it fully replaced signatures for in-store card payments in 2006.

  • Two checks in one payment: the EMV chip authenticates the card, the PIN verifies the cardholder.
  • Visa calls these cards PIN-Preferring Chip Cards: the chip's verification list puts PIN, offline or online, first.
  • Chip and signature leaves the check to store staff, and Visa lets merchants skip the signature.
  • To accept it, a business needs an EMV PIN-compliant terminal, one that meets the PCI PIN requirements.
  • Chip and PIN is for card-present payments only. Online, the issuer checks the buyer through 3D Secure.

Chip and PIN is the name the UK gave to EMV chip cards verified with a PIN. Here is what it means, how it compares with signature and contactless, and what a business needs to accept it.

What is chip and PIN?

Chip and PIN joins two checks at a store terminal. The card's EMV chip creates a one-time code for each payment, so the card cannot be copied like a magnetic stripe. Then the cardholder types a PIN, which either the chip (offline PIN) or the issuing bank (online PIN) checks. The chip proves the card. The PIN proves the person.

Visa calls a card set up this way a "PIN-Preferring Chip Card": a chip card whose verification list specifies "a preference for a PIN-based Cardholder Verification Method (either offline or online)."1Visa Core Rules and Visa Product and Service Rules, April 18, 2026 The issuer writes that order on the chip; see cardholder verification method.

The term comes from the UK. On February 14, 2026, UK Finance marked "twenty years since Chip & PIN fully replaced signatures for in-store card purchases." It reports "a 95 per cent reduction in losses to counterfeit card fraud over the last 20 years." Chip and PIN still accounts "for 30 per cent of all credit and debit card payments by value", with an average payment of £93, against £17 for contactless.2UK Finance, 20 years of change in payments: from Chip & PIN to mobiles, February 14, 2026

Chip and PIN vs chip and signature vs contactless

The same card can pay all three ways. What changes is who checks the cardholder, and who pays when a lost or stolen card is used.

Chip and PINChip and signatureContactless
Card readInserted, chip readInserted, chip readTapped card, phone or watch
Who checks the cardholderThe chip or the issuer, through the PINStore staff, if they check the signatureNobody under the country limit; PIN or phone unlock above it
Lost or stolen card fraud (Visa)The issuer's loss at an EMV PIN-compliant device (4.1.17.46)Can fall on the acquirer when the card prefers PIN and no PIN was checked (5.8.2.5)Visa's lost or stolen chip dispute (10.2) is invalid (11.7.3.3)

Source: Visa Core Rules, April 2026.1Visa Core Rules and Visa Product and Service Rules, April 18, 2026 This lost or stolen rule only applies in regions where Visa's liability shift covers non-counterfeit fraud; in the US it covers counterfeit cards only. See liability shift. Visa also lets a merchant process a payment "without the Cardholder signature" even when the card prefers one (section 5.6.1.1).1Visa Core Rules and Visa Product and Service Rules, April 18, 2026 Contactless limits by country are on our cardholder verification method page.

What a business needs for chip and PIN

Chip and PIN stops at the store door. Online, there is no terminal: the issuer checks the buyer through 3D Secure. For how that works, see our guide to payment authentication.

Frequently asked questions

What does chip and PIN mean for a business?

It means your card terminal reads the chip and lets the customer type a PIN when the card asks for one. Use an EMV PIN-compliant terminal from your payment provider, keep the PIN pad active, and insert the card rather than swiping or keying it. You never see or store the PIN: Visa forbids storing the PIN or the encrypted PIN block after authorization.

What is the difference between chip and PIN and chip and signature?

Both read the same EMV chip, so both resist counterfeit cards. The difference is the cardholder check. With chip and PIN, the chip or the issuing bank checks a secret code. With chip and signature, store staff compare a signature, and Visa lets merchants skip it. A PIN protects better against a lost or stolen card.

Does chip and PIN work for online payments?

No. Chip and PIN needs a terminal, so it only covers in-store payments. Online stores never ask for the card PIN. The issuer authenticates the buyer through 3D Secure instead, for example with a one-time passcode or a fingerprint in the banking app.
