Although a 1,000 TL contactless transaction is technically possible, we can say it is practically impossible, since banks would not take on that much risk. (The contactless transaction limit set by banks is typically 120 TL.) The limits on the card and the POS device affect whether a contactless transaction is carried out online.
When the Contactless limit on the POS is higher than the Contactless Floor limit:
- For transactions with an amount smaller than the Contactless Transaction limit and equal to or greater than the CVM Limit, CVM checks are performed and the transaction goes online. An online PIN or signature may be requested for the transaction.
- Transactions larger than the Contactless Floor Limit and smaller than the CVM Limit go online without CVM checks.
- For transactions with an amount higher than the Contactless Limit, a warning is given directing the cardholder to insert the card into the chip reader, redirecting the transaction to a contact transaction.
Let's examine these 3 supported limits for contactless transactions through an example.
Assuming the limit values are as follows;
Contactless Limit (Contactless Transaction Limit) : 250 TL
CVM Limit : 60 TL
Floor Limit : 50 TL
A contactless transaction made between 50.00 – 59.99 TL goes online without CVM checks.
A contactless transaction made between 60.00 – 249.99 TL goes online with CVM checks performed (requesting an online PIN or signature).

In this case, for a transaction made for 1,000 TL (transactions of 250.01 TL and above), a warning is given on the POS directing the card's chip information to be read, ensuring the transaction is carried out as a contact transaction by reading the chip.
