ATM services in Dublin and elsewhere in the east are expected to return to normal within days following yesterday's resolution of the month-old dispute at Brinks Allied.
SIPTU members at the company voted by 35 to 25 to accept new settlement proposals from the company and end the official strike begun last week.
The dispute, over new work practices, had disrupted cash deliveries to ATM machines at locations other than bank branches and retail outlets since the end of July. About 10 per cent of ATMs in the affected areas had ceased to function.
The Irish Payment Services Organisation, which represents the banking sector, said yesterday these should be back in operation in the next few days.
A spokeswoman, Ms Jennifer Chamberlaine, said the banks would work closely with Brinks Allied to get the out-of-service machines "up and running as rapidly as possible".
The IPSO was "delighted" that the dispute had come to an end.
Workers had refused to implement the work practice changes sought by the company, claiming they would leave them more vulnerable to attack during armed robberies.
They were particularly concerned about a management direction that drivers leave the scene of a robbery, even if that meant abandoning a colleague.
As a result of the deal agreed yesterday, the "drive away policy" has been rendered unnecessary, SIPTU said. The company has also offered to pay €375 to each worker involved to compensate them for loss of earnings during the dispute, the union said.
This is half the amount proposed by the Labour Court in a recommendation which was accepted by the workers, but rejected by management.
SIPTU security services branch secretary Mr Kevin McMahon said the settlement addressed SIPTU's main concerns over health and safety.
"As part of the new security arrangements, cash will be transported from vehicles to locations using smoke/dye boxes which the crew members have no access to, and in the event of unauthorised tampering with the boxes, the cash will be destroyed."
Brinks Allied managing director Mr Alan Jordan said the new procedures would make it "virtually impossible for armed criminals or other opportunists to grab cash". The safety of crews would also be enhanced and ultimately customers would benefit.
