In this insightful talk at Payment Village, Sanjeev Sharma, a payments legend with a distinguished career spanning Broadcom, Visa, Meta, and currently GoFundMe, delves into the transformative power of **network tokenization** in combating payment fraud. Sharma, who was instrumental in writing the initial specification for network tokens at Visa, provides a comprehensive overview of how this technology has fundamentally reshaped the landscape of digital payments, making transactions significantly more secure. He highlights that while many consumers may not explicitly know what a network token is, they have almost certainly used one through services like Apple Pay, Google Pay, or even Netflix.
AI review
A competent, well-structured explainer on network tokenization from someone who genuinely helped build the spec — that pedigree gives this real credibility. But it stays firmly in tutorial territory: clear, accurate, well-organized, and unlikely to teach anything new to anyone already working in payments security.
