NOTE: this may be short, but is just explaining the advantages and disadvantages of EFTPOS and EPOS. I hope this could help some of you in someway or another.
EFTPOS means Electronic Fund Transfer at the Point Of Sale; this is used for people who want to purchase things with credit card. EPOS is the abbreviation for Electronic Point Of Sale, the bookshop till system used for sales data and stock control; this is mainly for people who pay with cash.
EFTPOS is quite good for large company, and for people who like to pay with credit card over the phone or over the net. This can be good as it is fast and quick, however it can also be dangerous and sometimes embarrassing. This is because if using a credit card at a shop, the owner could be rejected because of an over draft, or if paying over the net, a hacker could see all the credit card details and could take money or diverse the money from the buyer to the hacker.
However EPOS could be easier, this is because you can pay upfront and not risk of having your details being seen, but you do have a risk of your money being stolen or having it lost, if it were a credit card you could easily lock it and prevent the thief from accessing your bank account
