Enforceability of Electronic Signature
We evolved from Telegram as an electronic communication even though it did not explicitly have the instructor’s signature. However, a telegram was accepted as enforceable communication. We then moved to send manually signed documents through fax to recipients. Even though the original document was signed manually, only the signature image got transmitted through fax machines and such fax was accepted as an enforceable document. When we changed over from signing charge slips manually to entering a PIN in credit card swipe machines, the entry of PIN was taken equivalent to signing manual charge slips. In electronic banking, entering OTP and authorizing a payment electronically is equated with signing a cheque to authorize payment to the payee.
