Is e-voting currently used in any elections with EMB participation?

According to a paper titled, Secure e-Government Services: Protection Profile for Electronic Voting – A Case of Tanzania, the electoral system currently used in Tanzania is mainly the controlled paper-based voting known as “First Past the Post”. https://secprj.dsv.su.se/secure-egovernment/document/ISTAfrica.pdf

Also, the Commonwealth Observer report on the 2010 General elections in Tanzania outlines  that according to legislation and regulations, some of the key features and safeguards for the conduct of opening and voting were: Prior to opening, the ballot boxes were to be shown as empty to party agents and then sealed. The ballot boxes were individually numbered, as were the seals. Voters had to prove their ID by showing a NEC/ZEC-issued Voter Card, which included a photo. The voter registers contained photos of voters for ID verification purposes. A voter had to be on the voter register in order to be allowed to vote. Ballots had to be stamped with the official polling station seal. Voting had to be in secret. Voters had ink applied to their finger after having voted to prevent double voting. http://aceproject.org/ero-en/regions/africa/TZ/tanzania-final-report-general-elections-commonwealth
