Android POS

In order to make the most out of Worldline's services and to ensure the proper operation of your POS, it is necessary to update your terminal, so that it is always running the current version. An updated POS is equipped with all the new functionalities and is in line with the International Regulations that govern transactions.

You can check the version of your POS by looking at any transaction receipt. Click here (content available in Greek) to see the list with the latest software versions for every terminal model.

Acquiring a Worldline POS is quite simple.
Browse through our POS page and select the solution that suits your business needs.

The first Worldline invoice is issued and sent within the first 15 days of the following month from the one when the initial activation of the services and products offered by Worldline took place. Each subsequent invoice is issued in advance for the service period to follow, i.e. within the first ten days of the last month of each current invoicing period. 

You can pay your invoice in your preferred bank (via cash or e-banking) based on the following board:

• By credit, debit or prepaid card (Visa/Mastercard/American Express/Diners) via online payment at worldline-processing.gr, by visiting the “Invoice payment” section, entering the payment code that can be found on side A of the invoice, and the payment amount.
• At a bank branch, via Web Banking or Phone Banking, by providing the payment code that can be found on side A of the invoice and selecting: Payments > Worldline
• Via a standing order for debiting your Alpha bank or Eurobank account, so that your invoice can be paid automatically on the due date displayed, if sufficient balance is available. You can set up a standing order at any branch of the above banks.
  
  Our invoices clearly state their due date and should be paid within the deadline.

If your invoices are sent to the wrong address, please send us the correct contact details at support@worldline-processing.gr.

Guidelines for secure transactions

Please review the information below to ensure that a transaction is secure and read about some signs that may indicate the opposite.

1. Contact the approvals center and ask for telephone approval stating “approval code 10”, if the appearance of the card (shape, size, colors, shape display, security features) or the overall holder’s behavior raise suspicions.
2. Use your card once for each completed transaction of the holder in your business, irrespective of the number of goods purchased or services provided and their individual or total value.
3. If the customer is required to enter the PIN to complete the transaction, give them the ability to do so securely, without it being seen by others.
4. Never carry out a transaction when the holder of the card is not present; do not accept powers of attorney or copies of ID cards presented by third parties to perform transactions with the cards of others.
5. Be reluctant to perform remote transactions as they involve a much greater risk than those carried out with the physical presence of the card (remote transactions are governed by specific terms and can only be performed after signing an Additional Deed with the Bank).
6. Remote transactions involve a significant risk that each business undertakes when they commence a collaboration with the Bank, by signing the additional deed for transactions with an open keyboard. The risk stems from the fact that the real holder’s consent to the remote transaction cannot be demonstrated in the same manner as in transactions that take place with the presence of the card (signature on the receipt, use of PIN).
7. Do not break down a transaction to smaller ones in order to force its approval. The provision of approval by the issuer bank is related to the creditworthiness of the holder and does not guarantee the lawfulness of the transaction.
8. Regarding the use of the “Pre-approval & Completion” functions, keep in mind the following: Pre-approval of a transaction is valid for 30 days. If the 30-day period has elapsed, you will have to receive a new pre-approval. The pre-approval of a transaction and its completion will have to bear the same approval number and the two actions have to take place within 30 days. The pre-approval of a transaction and its completion may feature a different amount, but the completion must not have a greater amount than that of the pre-approval. The pre-approval of a transaction and its completion have to be performed using the terminal of the same Bank, otherwise the transaction cannot be processed by the Bank that issued the card.
9. For security reasons, do not keep a record of your customers’ card details. Always ensure that your business is PCI-DSS certified.
10. In the event of partial or total cancellation of a transaction, always credit the card you charged initially. Never give the customer cash or refund the amount to another card. Keep your copy and any supporting documents for the transaction in good condition for at least 12 months. Send immediately the copy of the transaction to the Bank when so requested.
11. For even more advanced transaction security, if you have Worldline Android POS, we suggest that you lock functionalities that you do not use or you want to ensure that only those authorized have access, such as the Refund feature. Choose “Settings” in the app to lock the functionalities and then choose “Other Settings” to proceed with a ”Refund” using a PIN that you have set.
12. Take all necessary measures to protect customer data on your business’s electronic systems (e.g. passwords, firewalls, controlled personnel access).
13. Check that the card is signed and compare the signature with that on the receipt of the POS terminal, when a holder’s signature is requested on the receipt.

What to watch out for

Watch out for situations where the customer:

• tries another card when a transaction using a previous card has been rejected and the cards do not have the same surname;
• makes high-value purchases using different cards;
• makes a lot of purchases without considering the size, quality, color or price;
• tries to distract you so that you will carry out the transaction without performing the necessary checks;
• tries to expedite the purchase before the store closes;
• changes opinion about the purchase when they realize that the merchant is calling for approval of the transaction;
• is very anxious and behaves strangely during the process;
• buys goods in a hurry;
• buys a lot of bulky high-value products and collects them personally on the spot;
• asks you to break down a transaction to contactless transactions of a lower value for which it is not necessary to enter a PIN.

The basic requirement to use a transaction cancellation is before closing a batch.

You should use a Return transaction to cancel a transaction after closing a batch.

Note: Cancellation in contactless transactions is not possible. To cancel the transactions that have taken place intact you will need to select the Return transaction with the same amount.

Regarding the Android POS devices, for both transactions you must select “Cancel” on the device. Then, depending on the status of the batch (closed or open) in which the transaction is located, the POS will automatically proceed to the corresponding Cancel (open batch) or Return (closed batch ) action, without the need to take any further action.

The socket contains all the transactions made through your POS terminal at any given time. It is the equivalent Z report of your cash register.

The socket has to be sent daily, so that the transactions made through the POS can be credited to your bank account.

Please send us your request at support@worldline-processing.gr and we will inform you through email about the completion of the request.

After making your first transaction, POS will automatically contact the main transactions system and receive the appropriate time.

Alternatively, you can confirm that the POS has received the proper time by performing a Ηandshake/Synchronisation check.

Please proceed as follows to restart your POS device, according to your model:

Please proceed as follows to restart your wireless POS by removing its battery, according to your model:

If your POS is wired, please change the position of the POS power supply on the power strip and confirm that the cable is properly connected to the power outlet, but also that it is the correct power supply. If the issue persists, please contact us at support@worldline-processing.gr to replace the power supply.

If your POS is wireless, please check the POS battery charge. 

Worldline Android POS offer to businesses the possibility to lock functionalities that they do not use or it is important to ensure that only those authorized have access. The purpose of this feature is to make transactions as secure as possible, as well as to avoid mistakes.

Refund lock

Refund is the process of reimbursing the customer for a transaction which has already been completed. It occurs when a transaction has already been approved and the business has proceeded with the close batch. To initiate the refund, the customer contacts the merchant directly.

We encourage you to lock the refund functionality to ensure that only those authorized in your business have access. Choose “Settings” in the app to lock it and then choose “Other Settings” to proceed with a ”Refund” using a PIN that you have set.

“User Code” is a new feature of Worldline POSsible that will facilitate the management of your business, if you need to separate transactions based on a code that will be associated to them and will identify which POS user performed the transaction.

This code will accompany the transaction in accounting, it will be displayed on the receipt, as well as within Worldline apollo, Worldline's free platform for transaction monitoring. This way, not only will you know at all times which POS user carried out a transaction, but you will also be relieved of collecting notes and you will contribute to reducing paper consumption and to our common efforts to protect the environment.

If, for example, you are a petrol station owner, each employee can enter their user code along the payments they receive from customers, and you can track transactions per employee, shift, etc. Similarly, at a restaurant, transactions can be monitored per waiter, along with the tips.

How to set up a User Code?

You can set the User Code yourself within the application, by selecting “Settings” and then “User Code”. You have the option to either choose a code that will be automatically entered for all transactions, or for the terminal user to fill in the code they wish for each transaction.

If you cannot find the “User Code” option under “Settings”, make sure that your terminal is turned on and connected to WiFi or Ethernet at night-time, when automatic updates take place, so that it can be updated with this functionality as well as all the upcoming ones that the Worldline POSsible software of your Android POS will soon be equipped with.

What are MO/TO transactions?

MO/TO (Mail Order / Telephone Order) are payments made without the presence of a physical card. That is, the customer can place an order and pay by providing the details of the payment card by telephone or by email.

What changes with MO/TO transactions?

MO/TO transactions are considered high risk transactions due to the manner in which card details are sent, i.e., via phone or email. At Worldline, following the International Security rules and in line with PSD2 legislation, we upgraded the manner in which you receive MO/TO payments through Worldline POS terminals. Please follow the instructions below depending on your terminal type.

How can I carry out a Mo/To transaction on the Android POS terminal?

You can only carry out a Mo/To transaction if you have a received the relevant approval from the bank you collaborate with. Select “Other Services” and “Mail-Telephone Order” for the transaction you want to carry out (simple purchase or pre-approval). Follow the steps to complete the payment and send the receipt to your customer via SMS or email, if they request it.

If you cannot find the “Mail-Telephone Order” option under “Other Services”, make sure that your terminal is turned on and connected to WiFi or Ethernet at night-time, when automatic updates take place, so that it can be updated with this functionality as well as all the upcoming ones that the Worldline POSsible software of your Android POS will soon be equipped with.

The duration of a wireless POS battery depends on its use.

More specifically, it depends on the frequency of the transactions, the signal quality of the telecommunications provider and the time the device is on stand-by mode and ranges from 5 to 8 hours.

• The duration of the first charge of your wireless POS should be at least 4 hours.
• After the first charge, the POS should be charged for 1-2 hours. Check the battery indicator signal on your screen.
• The battery indicator should not be less than 2 bars.
• To ensure a good battery condition, the POS should be cycle-charged and should not be constantly connected to a power supply.
