Commonly asked questions about Samsung Pay

Samsung Pay transactions are authorized with a PIN, fingerprint, or iris scan. After repeated failure to authenticate, Samsung Pay will erase all card data. Also, each transaction uses a random token instead of the actual card number, which means no real information from the original card or account is shared by Samsung Pay. Finally, using Samsung Knox technology, the phone is constantly monitored for signs of malicious attacks or vulnerabilities. If the phone is ever compromised, the card information is still safely encryped within a separate, secure data vault. If your device is ever lost or stolen, you can remotely lock or erase Samsung Pay data  using Find My Mobile.

You can register up to 10 payment cards in Samsung Pay.

The number of devices that you can register per card varies for each issuer. Please contact your card issuer for details on the number of devices that you are allowed to register per card.

The current list of Samsung Pay supported cards includes :

* Public Bank supports both Credit and Debit cards, except PB RCB Elite/Gold Debit Card, PB Mastercard Lifestyle Debit Card and PB UnionPay Lifestyle Debit Card.

Samsung is continually expanding the list of payment cards you can register to Samsung Pay.

Tokenization is a method of protecting payment card information by substituting the card's number with a unique alphanumeric identifier, generated using proprietary algorithms. The unique identifier, or token, is then used for sending the transaction to the card's payment network, where it is decrypted and the transaction is authorized. The actual card number is stored in a secure vault (with the payment processor or bank), and does not reside on the merchant's or Samsung's systems.

Tokenization is being used to reduce security risks inherent in the collection and transfer of highly sensitive data between merchants and the card's payment network. Tokenized data is not mathematically reversible, and is useless unless you have the original key used to create the token, limiting the chance of your payment information being stolen or compromised.

The transaction is seamless and requires no changes on the part of the merchant or consumer.

Samsung Pay is available exclusively to users with a compatible Samsung device. Gift cards can be sent from Samsung Pay to non-Samsung users.

Both Apple Pay and Android Pay rely on Near Field Communication (NFC) technology to make contactless payment. These services are limited to merchants with NFC-enabled payment terminals. Merchants are required to upgrade to a new payment terminal with NFC capabilities in order to accept Apple Pay or Android Pay. Samsung Pay, on the other hand, uses both NFC and Magnetic Secure Transmission (MST) technology, making it work with nearly all current payment terminals. Some payment terminals may require software updates.

No. Samsung Pay does not have access to your bank accounts.

With very few exceptions, corporate card issuers do not allow their cards to be used with a mobile wallet. Contact your card issuer at the number printed on the back of the card for details on their specific policies.
