The payment process at the point of sale is stan-
dardised for all cards with ep2. A variety of card
types are in cir culation today.
Payment functions
ep2 offers a full range of transaction modes and
functions. The transactions activated on your
terminal are determined by the settings in the
service centre as global parameters and by the
individual card processors.
e.g. Tip:
This transaction type is often used in the hotel
and restaurant industry. In the retail business,
however, it is unnecessary.
– Depending on the payment function and
credit card processor, different minimum/
maximum amounts, day limits, etc. can be
defined.
– Functions are described in general in the
sections that follow. Please note that
some transaction modes and functions
may be inactive on your terminal.
Caution for offline transactions!
Offline transactions are stored in the security
section of your terminal and submitted to the
card processor by means of the daily closing.
This can be carried out manually by the terminal
operator or automatically.
Should the security section of the device be
defective, intentionally damaged or stolen,
the transactions that have not been stored
will be lost.
For this reason, we recommend that you:
– Meticulously retain all sales slips.
– Carry out a daily closing every day or more
often.
– Always carry out a daily closing before
making installation changes, etc.
– Always carry out a daily closing for antici-
pated longer absences from the business.
– A closing must be carried out for seasonal
operations, at the end of the season.
