Less money is to be stored in cash machines in a bid to stop the ongoing spate of ATM thefts in the region.
Local operators have agreed to reduce the value of currency loaded into hole-in-the-wall dispensers which are deemed vulnerable, ATM network Link said.
Since March, 11 machines have been stolen in ram-raids, using various heavy machinery including diggers and cherry pickers.
Nine other ATM thefts have been attempted.
The dispensers targeted have invariably been in quiet rural locations.
Link announced that its members have been co-operating with the police to implement a range of additional security measures.
While the network provider said it would be inappropriate to detail all the specific steps taken, it did reveal that a cash limit was being put into operation in selected ATMs.
"These reduced limits will remain in place for as long as it is deemed necessary," said a spokesman.
"Every effort will be made to minimise the impact of these changes and we would like to apologise in advance for any inconvenience this may cause should customers experience any temporary drop in service levels, but ask that they support our efforts to prevent criminals profiting from this type of crime through this difficult period."
"Our priorities remain to continue to provide ATM services to as many communities in Northern Ireland as possible, while protecting our business partners' premises and bank branches."
Link is offering a reward of up to £25,000 for anyone who provides information which leads to the ATM thieves being caught.
