Hi Daniel Lim, thank you for your question. Upon expiry of NETS CashCard, you will see an error message “ERR” appearing on your IU. There is no need to rush down to an inspection centre. You may obtain an immediate refund on a non-damaged card from any DBS/POSB, OCBC or UOB ATM (select 'More Services'). Check more details here: https://www.vicom.com.sg/Our-Services/iuservice
