SECUMEM avoids changes and deletes
USB memory for protocols, receipts and contracts.
Once written data cannot be deleted or changed It is possible to add data or information.
Every event will be registrated in a journal
with time stamp. The internal time is not changable.
SECUMEM can be conneted as any ordinary USB memory to a PC without driver.
After 15 months the memory is looked and can only be read.
