One error jumped out at me quickly... contrary to the article, Lutherans in fact DO believe in the true presence of Christ in the Eucharist, though they call it consubstantiation, rather than transubstantiation. To a Lutheran, it is still bread and wine, but infused with the true presence of Christ. Another difference to a Lutheran is that the true presence is ephemeral, so that the once holy-always holy nature of Catholic Eucharist, does not apply from the Lutheran viewpoint (i.e., after their use during communion, they remain just bread and wine).
Some quick notes:
Altho ^some^ Lutheran traditions use the term Eucharist, confessional Lutherans agree that the term should be rejected as it implies a “memorial” sacrament.
Consubstantiation is a modern term meant to obfuscate the real meaning of the Sacrament of the Altar.
Your use of the term “infused” is better described as ‘in, with and under the Elements (hat-tip, Martin Luther).
In the sense of the preservation of the Host, you are correct. At the end of the Lutheran Mass, the elements are simply bread and wine, yet, confessional Lutherans handle and dispose of the “left-over elements” with due reverence.
As to receiving in the hand or receiving on the tongue, we should consider the Verba that says, “Take and eat.”. It appears that the apostles received the Bread/Body in their hands. (Cletus prefers to receive lingually from the Celebrant).

Who decides if the Eucharist is the true Body and Blood of Christ? The consensus of the majority of human beings? There are thousands of independent protestant groups in the USA, each with the same Bible, the same Jesus, but there are a great number of differences of interpretation about the same passages from the Bible! Where is the authority to give us the Truth that truly sets us free? My opinion? Your opinion? Is it all subjectivism and relativism and thus how can I be sure that I am following the right path that leads to eternal life since I am a subjective human being? Did Jesus Christ, Who is God, not know that there would be this problem, and did He not leave a solution for those with true humility and good will?
But it still isn’t transubstantiation.
Trans = transfer
Substantiation = substance.
No real Lutheran does this.
