Do you depend on SmartBenefits to pay for your daily jaunts around Metro-land? If so, pay attention: WMATA has announced some changes to the way that your transportation cash will be distributed. The coolest change? Instead of having to go to the farecard machine to download allocations to your SmarTrip card, your monthly balance will automatically be added whenever you tap your card to any Metrorail faregate, parking target or bus farebox, saving you precious seconds. The downside? Beginning in 2010, if, for whatever reason, you don’t use any public transportation for an entire month, the funds allocated will be credited back to your employer. While a scenario — outside of extended foreign travel — where you don’t use touch any sort of Metro farebox for 30 consecutive days is difficult to imagine (and most employers would presumably just roll it over), we can already imagine the kinds of epic complaints that could arise. The changes will also allow the option to allocate funds to a flex account which can be transferred between both parking and transit.
