It is to be noted that customers need to have their card present to get a refund. However, if the customer can’t come in-person with their card for some reason, the merchant will need to contact us to reverse the charge in order to process a refund. The merchant will need to inform us within 90 days of the sale.

How to settle and batch transactions

how to settle a batch Ingenico Tetra 3500

Settling a batch is the step that is required to deposit all transactions to the merchant’s bank account. We recommend settling once per day at the close of business for easier accounting tracking. We can also set up auto-batching through Acumen Connections by giving us a call. To do an end of the day report on your Ingenico Tetra Desk 3500, follow these instructions:

· Press the green enter button

· Scroll down and select ‘Settle’ from the menu

· Press enter key

· Select ‘All transactions’ option and press enter key

· You will be asked if you want to close.

· Select ‘Yes’ and press enter key.

The end of day report from your terminal should match the end of day sales in your POS software. If there are discrepancies it could be due to an overcharge or under charge or something not being rung up. Catching these at the time it happens means you can fix them right then while the information is fresh rather than waiting until the end of the month when you’re settling your books.

Ingenico Tetra Desk 3500 Common Support Questions

Your device can do a lot. At some point, you may have questions that aren’t covered in the above information. Here are a few frequent questions we face.

How to replace the paper roll in your Ingenico Tetra Desk 3500

Ingenico Tetra 3500 receipt paper roll

After printing countless receipts for transactions, you will eventually run out of paper and will need a replacement. You can order more receipt paper from Acumen Connections. Your Ingenico device supports 2.25 x 50-inch thermal paper. To replace the paper roll in your device, follow these steps:

· Lift up your machine so it stands upright

· Place your finger in the gap at the top and lift up till you hear a click

· Open the top flap (the contactless tap section should flip open)

· Remove the sticker from your replacement roll before inserting

· Slide the roll in and pull the end of the paper out to start the feed

· Close the flap

Forced sales vs manual key in explained

Ingenico Tetra 3500 force a sale

Oftentimes, merchants will accidentally do a forced sale when they want to manually key in a card number. If you were to key in a card number (instead of using the chip, tap, or swipe option), you would follow these steps:

· Select the ‘sale’ option

· Type in the product cost

· Type in your amount

· Manually enter the card number.

The force sale option is a very specific process. Under some very unique circumstances, there may be a time you need to pass a bank’s authorization process for a credit card. If you absolutely must do this, you need to call your provider (Acumen Connections) and inform them beforehand. This is because most banks will stop these forced sale transactions after those batches are settled. When this happens, you won’t receive the money for about a day or two.

It is advisable to follow the method described previously on setting a password. Block employees from accidentally making a forced transaction by requiring a password for the process.

    1. Just trying to reprint myself. I started just pushing buttons from the home screen and found when I just pushed the #9 button from the resting screen the third option there is reprint!

    1. Acumen Connections

      The terminal will always ask if you want a second receipt, you just have to say NO when it asks. Hope this helps!

  1. Is there a way to turn off the auto print of the end of day report. I come in to work the next morning, and if we had transactions the previous day, I have an end of day report printed out. It just waste my paper – we do not need that function active.

    1. Acumen Connections

      Unfortunately, the report can’t be turned off completely, but there is an option to simplify the report to significantly shorted it. Follow these steps to achieve that: Turn Off Detail Report in Batch Settlement Print Out
      1. Press #
      2. Press 3 – Setup Menu
      3. Press 5 – Trans Options
      4. Enter admin password: t8432678
      5. Press 4 – Settlement
      6. Press 1 – Settle Report
      7. From Settle Report
      –7.1. Off, if you do not want a detailed report
      –7.2. Summary – this will still result in a detailed report, do not use
      – 7.3. Detail, if you want a detailed report.

  2. My unit just reset, now everything is in Spanish. I tried to scroll through the menu, but it’s in Spanish and nothing looked obvious like “switch to English”. If anyone could help, that would be fantastic. Thanks!

  3. I have my own Online/cloud based POS system.. How can I get data from the Desk/3500 terminal into my system? e.g. The Auth code, last 4 digits of card used, type of card used and so on.

  4. I have an Ingenico Group Desk/3500
    1) Is there a way to have the “Card Issuer” printed on the merchant copy receipt? Currently the “Card Issuer” is not listed on receipts.
    2) Is there a way to list the different “Card Issuers” on the reports with each “Card Issuer” total sales? Example: Visa = $100/MC = $100/Disc: =$100 total daily sales = $200.00

  5. Our company have a Ingenico desk/3500. Need to know how to switch from a debit card to credit card when client don’t know their pin number. Thank you
