Steven Pearlstein’s insightful recommendation to pay Americans to vote a certain way [“Forget super PACs: A modest proposal for legalized bribery,” Business, Feb. 5] contained a flaw: It rested entirely on the trust that those receiving payment will vote the way they are paid to vote. Luckily, fixes are available.

At a minimum, we will need a more effective means of excluding access to the polls by less trustworthy people. More stringent voter identification requirements will help, but we need to build on this. A national voting card and exclusive use of electronic voting machines could quickly identify votes that deviate from the agreement and any voters reneging on what they are paid to do (a contract violation that could be made into a criminal offense).

Indeed, by the 2014 midterm election, it would be possible to embed electronic chips in all voters which, when activated by the incorrect voting transaction, could administer immediate punishment.

With a few additional refinements, Mr. Pearlstein’s proposal could get our nation back on the right path faster.
