Summary

Tap-to-pay technology, enabled by NFC, has become popular for its quick and secure transactions. It uses antennas to initiate radio communication between the card and reader, transmitting static data and a unique cryptogram for verification. The encrypted information is sent to the payment board and then to the issuer for approval. This technology is faster and more secure than swiping and has gained traction in recent years, although it took time for the US to adopt it.

Key Insights

💡 NFC (near field communication) technology, which relies on antennas, is at the heart of tap-to-pay transactions. It enables quick and secure communication between the card and reader.

💡 Tap-to-pay transactions utilize both static data (account number, expiration date) and a unique cryptogram for verification, making it difficult to replicate cards fraudulently.

💡 The encrypted information from the card is processed by the payment board and sent securely to the issuer for approval, ensuring a high level of security throughout the transaction.

💡 Tap-to-pay technology has seen significant growth, especially during the pandemic, with increased adoption and usage. Integration into public transportation systems and daily routines contributes to its popularity.

💡 The initial slow adoption of tap-to-pay in the US was due to the lack of businesses accepting it, expensive payment system changes for retailers, and slow consumer behavior change.

💡 The push to integrate tap-to-pay into more aspects of everyday life, including transportation systems, aims to increase adoption and usage beyond traditional payment scenarios.

💡 The introduction of NFC functionality in smartphones allows individuals to use their phones as active connections, making it easier for small retailers to accept tap-to-pay payments.
