17. The method according to claim 16, wherein the reference identifier selected in step n) corresponds to the highest identifier recognition probability of the second corresponding identifier recognition probabilities.
16. The method according to claim 1, further comprising the steps of: i) prompting the user to indicate whether the selected reference identifier matches the entered identifier; j) if the user indicates that the selected reference identifier matches the entered identifier, acknowledging the user as having entered a valid identifier; k) if the user indicates that the selected reference identifier does not match the entered identifier: l) providing a second plurality of reference identifiers, the second plurality of reference identifiers including every reference identifier except the selected reference identifier; m) repeating steps e) and f) for every reference identifier included in the second plurality of reference identifiers, each one of the reference identifiers of the second plurality of reference identifiers being associated with a second corresponding identifier recognition probability; and n) selecting from the second plurality of reference identifiers the reference identifier most likely matching the entered identifier based on the second corresponding identifier recognition probabilities.
