Use these bags to securely store, transfer, and deposit cash from places of business or cash collection to banks or long-term storage places. "Tamper-evident: if an attempt is made to open the bag between the time of on-site cash deposit preparation and opening of the bag by authorized bank personnel, it is "evident". Level 4 protection: the highest level of security in general commercial usage. Protects against application of force, cold, saliva, and heat. Pre-printed serial numbers in sequential order: if a cash deposit bag is lost or stolen between cash deposit preparation and opening of the bag by authorized bank personnel, appropriate bank controls should identify missing / out-of-sequence bag serial numbers. Our advanced FRAUDSTOPPER technology ensures that once our security bags are sealed, any attempt to reopen them will show clear signs of tampering.
