Just some tips on Cash Deposit Machine:

When you insert cash in the machine and it keep rejecting the notes that you replaces ( normaly happen to new notes )    please dont keep inserting the cash because these CDM machines have timing, if a transaction cant be fulfiled within certain amount of times, by defaults it will force accept your cash and the cash you failed to bank in will go the rejected notes bin.

The next thing you see is that the CDM will come out this message " OUT OF SERVICE ". The person queing behind you will start cursing you. Why i say this is that customer have complaint why the CDM do this and that, scolding us with all the #&^&*# and when we go and check the journal report we can see this customer was trying to insert the notes for more than 5 times which the machines unable to recognise it and it will kick start this step by force the cash into the reject bin.

However different banks setup their machines differently it depends on how sensitive they set it. From what i experience HSBC & MBB had it.
