Why protect your contactless cards?
Your wallet may contain several contactless cards, including an Oyster card and one or more bank cards. When they are not being used, those cards can potentially respond to compatible readers nearby.
Accidental Payment
A reader detects and accepts the wrong card instead of the one intended. This can happen when tapping in or out on transport, potentially resulting in an unintended fare or incomplete journey. A nearby person’s card may also be detected under suitable conditions.
Card Clash
Two or more cards respond simultaneously and the reader cannot select one, causing a failed payment attempt or a transport barrier not opening.
eSkimming
An attempt to interact with or read a contactless card without its owner’s permission. The actual risk depends on the card, reader and circumstances.
How the TfL Card Shield works
Each shield uses passive RFID/NFC shielding technology to help reduce communication between a compatible contactless reader and cards positioned behind it.
The shield is designed to sit in front of cards in the same slot of your existing wallet or cardholder. Protection depends on the shield’s positioning relative to the cards and reader.
Each pack contains two Card Shields.
How to use your Card Shield
Position Place a shield in front of up to three contactless cards you wish to protect.
Store Keep the shield in front of the cards you want to protect, in the same card slot inside your existing wallet, purse or cardholder.
Select When you need to pay or travel, take out the Oyster card or bank card you intend to use, separating it from the shield and other cards.
Tap Present only your chosen card to the reader.
Replace Return the card behind the shield after use.
