If the elderly cannot sign and cannot apply for a bank card by themselves, the guardian of their children can accompany them and sign on their behalf. The children can also stamp the signature with the elderly's personal seal on their behalf.

Since the handler himself cannot sign, it is best not to self-service at the smart terminal, but to wait in line at the counter. When paper documents need to be signed, the elderly's children or relatives can assist them to help the elderly successfully apply for bank cards or passbooks.

Since bank staff are only responsible for business guidance and cannot help customers handle business, it is the most appropriate way for the elderly relatives to come forward to assist in signing.
