According to Odaily, four German companies—DG Nexolution, DZ Bank, Festo, and Giesecke+Devrient (G+D)—have collaboratively developed a new prototype solution to support the use of tokenized deposits for machine-to-machine (M2M) payments in offline mode. This technology is part of the Industry 4.0 initiative, enabling businesses to rent industrial machines on a pay-per-use basis without the need for direct purchase.

The solution addresses the challenge of making payments in environments without internet connectivity, such as underground mines or secure facilities. The prototype includes two wallets integrated with commonly used control units on the machines. Smart cards are employed to deposit money into the wallets, allowing machines to transfer funds between them.
