First, different POS machines, the account number and password are different, for example:
1, ICBC pos machine, operator: 201; password: 000000
2, Agricultural Bank POS machine, operator: 01; password: 0000
Sometimes by logging in the account number and password, the online check-in is not triggered (that is, the POS machine does not dial the host and jumps directly to the standby interface). This only implements the login of the account. When you make the first online transaction, the POS machine First check in by default, then online transactions.
For example, if the POS machine does not sign in, the direct card swiping will be particularly slow, because the POS machine first signs in by default, and then reads the bank card for consumer transactions.
Second, the purpose of the sign-in
1. POS machine sign-in has two purposes:
(1), connect the host to prove that the pos device is legal
(2) Download the latest work key.
2. Steps:
(1). Set legal work key, bank card center phone number, merchant number, terminal number
(2). Dial-up connection
(3). Return to sign-in success or failure
