An IT issue affecting eftpos terminals caused problems for Woolworths customers this morning, forcing stores to accept cash only.
Woolworths shops in NSW, Victoria, Queensland and the ACT were forced to accept cash only after eftpos systems were affected.
Stores in Sydney's south and west, as well as Woolworths in Mawson in the ACT, Pakenham in Melbourne, and Stafford in Brisbane all experienced an IT issue that interfered with the eftpos system.

Between 10 and 20 stores were affected by the outage.
"We'd like to thank customers for their patience with an IT outage affecting eftpos in a small number of stores," a spokesperson for the supermarket told 9news.com.au.
"Stores remained open with cash still being able to be used.
"The cause has been identified and eftpos is being restored.
"Again we thank everyone for bearing with us this morning."
Stores resorted to handwritten signs explaining the situation.
"We temporarily have no eftpos due to no internet," one sign read.
"Cash only, sorry for the inconvenience."
Most affected stores are now back online.
