Transporting bags of cash from shops to banks would be safer if pickups came at less predictable intervals, perhaps days apart. The trouble is, that would hit a shop鈥檚 cash flow. No longer, says De La Rue of Hampshire (WO 02/45042). Their new system uses money sacks with wires woven into their fabric and connected to a security tag. The tag contains a GPS satellite chip and a radio transmitter. After cashing up each day, shop staff seal their takings in a sack and tell their bank the amount of money in the bag. The bank then credits the shop鈥檚 account with that amount, on trust. The bank can then wait several days to collect a batch of bags, creating 鈥渁n unpredictable collection pattern鈥� that will confuse anyone who is planning a heist.
