The systems and procedures used by Piraeus Paycenter prevent unauthorized third parties from accessing its data and information systems.

What is Paypal
Paypal is the most widespread online electronic transaction service, which is used for secure transactions on the Internet and undertakes to pay online stores on your behalf, without requiring your constant intervention at every step. Paypal belongs to eBay Inc., the online shopping giant, and in Europe it operates under the supervision of PayPal (Europe) based in Luxembourg. Paypal operates in 190 countries, with over 113 million active users and can manage 25 different currencies. The money handled by Paypal in 2011 exceeds 118 billion dollars!
How Paypal works
Paypal functions as an intermediary account for you for the online stores and services with which you transact. The Paypal account that is created when you register with it, is funded by you with the amount of money you wish and only when you decide to, using your credit or debit card, as well as your bank account. The use of Paypal in a payment or transaction requires the user only to enter the information that was declared during registration, i.e. your email & Paypal password. From there, it undertakes the completion of the transaction without disclosing any of your information (name, credit card, etc.), just as if Paypal were paying for you!
Security and Paypal
Paypal’s operating specifications are of the highest standards and synonymous with online security. Transactions through Paypal are made in a fully secure environment with continuous use of SSL security protocols and AES-256bit encryption. All Paypal pages, from user registration or login to the simplest confirmation messages, are carried out in an environment of secure and encrypted connections and any data transmission is practically impossible to intercept in real time.
Paypal as an intermediate electronic transaction platform has mechanisms for monitoring each transaction for several months from their inception. In addition to the secure transaction environment, the user has at his disposal the possibility of communicating with support staff in case of a problem, the possibility of disputing a charge and refunding money.
Advantages of Paypal
Paypal is superior in many ways to most payment and transaction methods, e.g.:
Your credit card or bank account information is securely stored on Paypal servers and is NOT made public to the seller, who only receives the money for your purchase, without ever learning anything else about you.
All Paypal pages are strongly encrypted, without the possibility of interception of your personal or financial information.
Paypal constantly selects and evaluates cooperation with an online store, thus increasing the seller’s credibility.
Using Paypal in your transactions saves you from repeatedly typing your information, since all you need to do is log in to your account and press the Checkout button.
Paypal has specialized staff to protect against fraud or malicious charges. In case of a problem, you can contact them for the possibility of a refund to your account.
Sign up for Paypal
Signing up for Paypal is done simply by using your email address as your primary identifier, along with a secure password of your choice. After confirming your registration, you must enter your credit or debit card details in the Paypal environment, in order to be able to send money to your Paypal account or charge your card and/or bank account.
Paypal notifies you by email about the progress and completion of each transaction, as well as for any suspicious attempt to access your account, to protect your information. Your personal data remains secure on Paypal servers and only you can change or delete it.
Payment methods
Paypal transacts on your behalf and the transfer of money to your Paypal account is done in the following ways:
By connecting a credit card: Every time you make a purchase, Paypal will charge your credit card, without of course sharing its details with the seller/online store.
By connecting a debit card: It works the same as for a credit card, except that every time you make a purchase, Paypal will charge your debit card and it in turn will withdraw the money from your bank account. In case your account does not have money, the transaction will not be able to take place, so make sure there is sufficient balance.
By connecting a prepaid card: In this case, each transaction deducts the corresponding amount from the balance of the prepaid card and when the money runs out, you refill it with any amount you want. Prepaid cards are issued by any bank.
By bank transfer (wire transfer): You transfer the money from your bank account to your Paypal account using a process provided by Paypal. In order for a transaction to take place, your Paypal account must have sufficient funds. Not recommended, mainly due to the long transfer time (5-7 days)
