Paperback / Hardback

Few technologies have reshaped a nation’s habits as quickly—or as profoundly—as UPI. In less than a decade, it transformed how India does business, breaching barriers of literacy, language, culture and geography to connect everyone from street vendors to global corporations through a simple, instant, and robust payments network.

Its success can seem almost inevitable in hindsight. But every single one of those crores of daily transactions is founded on vision, technological ingenuity, institution building, improbable partnerships and
years of painstaking effort.

Spun as a taut, lucid, fast-paced tale by industry veterans Santanu Paul and B. Sambamurthy, Cashless Nation is the chronicle of a nation reimagining the relationship between citizens, markets and the state—and, in the process, creating a model that has captured the world’s attention.
