Advantageously, the invention is a true competitor for money transfer systems, such as Western Union, Bitcoin, Swift, Visa, MasterCard, etc. The invention is the example of the economy going cashless and killing money transfers as a class. Conventional digital transactions facilitate electronic payment, such as money transfers, payment card charges, e-commerce transactions and any other types of transaction. However, in multiple circumstances, payees may be unbanked people (e.g., children that need money to buy something) or may have no payment card (e.g., may lost card), while payment card fund transfers may be expensive, time-consuming, and cumbersome for financial institutions. Thus, there is need for an improved approach. The invention discloses an automated digital method of providing or sharing access to a payment card and / or similar financial account or a non-payment card and / or similar non-financial account or non-card product, transacts between individuals or legal entities without physical transmission of a payment card, non-payment card, non-card product or its credentials, even without a recipient of an access having a payment card and / or financial account or a non-payment card and / or similar non-financial account or non-card product, particularly by providing or sharing access to a payment card and / or similar financial account or a non-payment card and / or similar non-financial account or non-card product of a sender.
