I refer to TODAY’s report ‘10000 to trial new ez-link card’ (27th August 2008). The initiative by the LTA to integrate non-cash transactions using contactless cards into one single card should be applauded. This is the way to go to facilitate convenience between public & private transportation. LTA should take this opportunity to ensure that its vendor use ‘24-hour heat resistant’ materials during the manufacturing process of this new ez-link card.The reason is because, the ‘blue butterfly’ series cash card series launched by Nets earlier this year had caused inconvenience to numerous motorists. For example, my recent purchase of a ‘blue butterfly’ series cash card in place of a faulty cash card of the same series, still resulted in two ERP summons this month despite having ensured that the newly topped up cash card is securely placed in my vehicle’s IU*. Puzzled I took time off to send my vehicle for an IU inspection. According to the Vicom official, the problem was due to the fact that the ‘blue butterfly’ series cash card could only withstand 4-hour of heat, resulting in damages rendering it unreadable by the IU.I find it technologically puzzling why the newer ‘blue butterfly’ series cash card could actually be less heat resistant compared with the older cash card series. To facilitate motorists’ convenience, LTA must play its part to ensure that the vendor manufacture ‘24-hour heat resistant’ cards.*LTA subsequently waived off these two ERP summons upon appeal. **The above feedback was sent to LTA via its feedback portal.
