INCUMBENT John Dramani Mahama has won a second term as Ghana's president by a narrow margin over rival Nana Akufo-Addo.

However the opposition is crying foul claiming some tallies were rigged. But interestingly the opposition has not challenged the validity of the BVR systems, which are also used in Ghana.

There were delays after a small percentage of BVRs failed on Friday which forced some polling stations to reopen on Saturday to clear the backlog. But in general the fingerprint readers have been accepted by politicians and voters as trustworthy.

The BVR machines weed out those who want to register twice or vote under a false name. They will make the 2013 election the most accountable in Kenya's history.

IEBC chairman Ahmed Issack Hassan has been in Ghana last week as an election observer. He will have witnessed the BVR problems, mainly in hot areas, so he should plan ahead to send backup machines to certain wards.

Ghana has been one of Africa's most stable countries for the last 30 years but Kenya came close to meltdown in 2008. We can't afford any disputes in this election. The IEBC team needs to iron out any technical issues well in advance.
