TEF solutions for your company Big businesses need big solutions.

What is TEF?

TEF means “Electronic Transfer of Funds”. It is a system recommended for establishments that have a large volume of transactions and in need of greater control over the sales. The TEF is integrated into the front of the cashier of your store and it allows you to initiate the transactions direct of the origin.

It works as follows: a card reader (a PinPad) is connected to the TEF, installed in a computer, tablet or mobile at the point of sale. This TEF is responsible for controlling the inventory, record sales, engage the reader and send the transaction data to Stone.
