QR決済

• Reading: キューアールけっさい
• Romaji: kyu aru kessai
• Kanji breakdown: 決 (decide, settle) + 済 (complete, finish) → settlement; completing a payment
• Pronunciation: /kjuː.aː.ɾu.kes.sa.i/

Meaning

QR code-based mobile payment, the dominant cashless method in Japan led by apps like PayPay.

QR決済 became Japan's most popular new payment method thanks to aggressive marketing campaigns by PayPay and competitors. Unlike tap-to-pay (Suica/IC cards), QR payments work by scanning or showing a QR code. The technology was already huge in China, and Japanese companies adapted it for the domestic market. It's now ubiquitous from convenience stores to street food vendors.

Examples

1. 現金もカードも持ってないけど、QR決済あれば困らない。 I don't have cash or a card on me, but as long as I have QR payment I'm fine.
2. 個人店でもQR決済導入してるところ増えたよね。 More and more small independent shops are adopting QR payments, right?
3. QR決済のキャンペーンで20%還元とかあった時代が懐かしい。 I miss the days when QR payment campaigns gave you 20% cashback.
