    In a banking security system that monitors transaction patterns, develop a function that identifies the next palindromic transaction ID number greater than the current transaction ID to flag potential automated fraud attempts. The function should take a transaction ID as input and return the next possible palindromic number that could be used by fraudsters attempting sequential pattern-based attacks. The resulting palindromic number must be the smallest possible value larger than the input transaction ID.
