When is the last time you rode in a cab? Since Americans started making the gradual move from carrying cash to credit cards to carrying debit cards, certain services were stubborn to accept plastic payment. Amos Tamam thought of a way for one of those services to come into it’s own in the 20th century: accepting credit/debit cards for a taxi fare. Granted, it took some real time and effort to finally implement this feature, but if you are a frequent cab customer, this is very convenient.
Amos Tamam was able to ensure that this invention was his idea, he had to apply for a patent. That means filing detailed paperwork with the patent office in Washington, D.C., drawing of how to engineer the invention and either selling the patent to a company, or use it on a product you manufacture yourself. Amos Tamam obviously built this invention and placed it in his fleet of cabs. The rest is history.
