This is typically because we can't reach your employer to verify the funds. If it is outside normal business hours or over the weekend, SAM can’t always verify first-time users checks. We do not cash checks older than 21 days. Why isn’t my check cashing? There are a number of reasons why your check might not be cashed. What type of ID do you accept? SAM Machines accept driver's licenses, state IDs, Veteran IDs, Mexican IDs, Matricula Consular Card, Canadian IDs, tribal IDs, and more. With that said, SAM Machine fee rates are typically between 2-5%. What are the SAM Machine fee rates? The fee depends on the state, the type of check, and the store. Write ( Byte ( $6 )) // send ACK if ( ReceivedText is HOLD message ) then Exit // keep waiting. Write ( Byte ( $15 )) // send NAK Exit // keep waiting. Message ) Exit end end AddToMemo ( 'Received message:' + ReceivedText + Char ( lrc )) if ( ReceivedText is not valid ) then begin IdTCPClient1. Enabled := False AddToMemo ( 'ERROR! ' + E.

Following the flow chart you posted earlier is easier when using blocking I/O operations with the IOHandler's ReadTimeout property, eg: Personally, I would just get rid of the timer completely. end else begin // unexpected, do something. end else if b = $15 then // NAK begin // failure of previous message you sent. ReadByte if b = $6 then // ACK begin // read POS's next message. Receivedtext1 := (#6,true,true,IndyTextEncoding_8bit) Īs I said earlier, since the ACK/NAK is only 1 byte, you should use ReadByte() instead of WaitFor(), eg:ī := IdTCPClient1. I need to send ACK after every returned answer from POS.Īnswer := ()

How to receive ACK from POS terminal and other data from POS ? > (s, IndyTextEncoding_8bit) īut now program hangs for a while waiting for some response or something.
> Though I suspect the POS is actually expecting binary data for the message content, not hex-encoded strings, so try something more like this: Though I suspect the POS is actually expecting binary data for the message content, not hex-encoded strings, so try something more like this: I have worked in the past with STX/ETX protocols and a few POS protocols, you definitely need to send the, and as binary bytes, not as hex-encoded strings. If IOHandler.InputBufferIsEmpty then Exit Procedure TForm1.Timer1Timer(Sender: TObject) (edit7.Text, IndyTextEncoding_OSDefault) I need to send some HEX to POS terminal, amount of money, and POS will then check if credit card if validĪnd send me some answers.like this: ( message)ĮCR->POS: 303030303030303030303031303030313030302B303139313030312C
