Samsung Wallet can make in-store payments without an active internet connection after a card has been registered and activated. Samsung Malaysia says most cards allow up to 10 transactions before the wallet needs to reconnect and refresh, but the allowance depends on the card. Google’s published contactless-payment guidance does not confirm offline payments or give a transaction limit, so whether a Google Wallet tap will work offline is unconfirmed by that guidance.
For either wallet, set up and verify your card while online, check that it is supported where you are going, and carry a physical payment card. A retail payment tap is separate from setting up a wallet, viewing updated transaction history, or activating a transit pass.
Offline payment support at a glance
| Question | Google Wallet | Samsung Wallet |
|---|---|---|
| Can you pay in a shop without internet? | Google’s cited contactless guidance does not confirm offline payment or specify an offline allowance. Offline use is unconfirmed by that source. Google Wallet phone contactless guidance | Samsung Malaysia says in-store purchases do not require active internet after card registration and activation. Samsung Malaysia FAQ |
| How many offline payments? | Not stated in the cited Google guidance. Google Wallet phone contactless guidance | Samsung Malaysia says most cards allow up to 10 transactions before connecting to refresh; the allowance depends on the card. This is regional guidance, not a universal limit. Samsung Malaysia FAQ |
| Does setup need internet? | Set up a supported payment method, enable NFC, and make Google Pay the default payment app for phone contactless payments. Google Wallet phone contactless guidance | Yes. Samsung says internet is required to register and activate a card. Samsung Malaysia FAQ |
| Can you see recent transactions offline? | The cited Google contactless guidance does not state whether transaction history is available offline. Google Wallet phone contactless guidance | No. Samsung says an internet connection is needed to download recent transaction details. Samsung transaction-history guidance |
These are not equivalent offline specifications: Samsung’s transaction figure is specific to Samsung Malaysia’s guidance and qualified by “most cards,” while the cited Google guidance gives no offline limit.

What needs to be done before you lose connectivity?
Google Wallet
Before travel, add and verify a supported payment method while online. For phone contactless payments, Google says NFC must be on and Google Pay must be the default payment app. The reader also needs to accept contactless payments. Google’s documentation describes these requirements but does not promise that a tap will succeed without internet. Google Wallet phone contactless guidance

Samsung Wallet
Register and activate the card while connected. Samsung’s US support page also says internet is required when adding a card, and interrupted verification can stop setup from completing. A payment made later without active internet is a different task from adding or activating the card. Samsung US card setup guidance
Why an offline tap can still fail
Being offline does not guarantee that a payment will be accepted. The card, wallet, phone or watch, and destination must be supported; the terminal must accept contactless payment; and the issuer may still decline the transaction. Samsung notes that after payment data reaches the terminal, the merchant and card network handle the transaction. Samsung transaction-error guidance

Transit payments are a separate case
Do not assume that a wallet’s in-store behavior applies at transit gates. Google says acceptance depends on the public transport system: some systems support contactless bank-card payments, some use stored transit passes, and availability varies. Activating a transit pass requires the device to be online. Check the transport agency’s current instructions for the destination. Google Wallet transit guidance
