Odaily Planet Daily News: Four German companies - DG Nexolution, DZ Bank, Festo and Giesecke+Devrient (G+D) have jointly developed a new prototype solution to support M2M payments using tokenized deposits in offline mode. This technology is part of Industry 4.0 and allows companies to rent industrial machines on an on-demand basis without having to buy them outright. The solution is designed to solve the problem of machines making payments in environments without internet connectivity, such as in underground mines or secure facilities. The prototype demonstrator has two wallets, into which the control units commonly used on machines are integrated. Smart cards are used to deposit money into wallets, and machines can transfer money between wallets. (Ledger Insights)
