If you require enhanced security and faster processing then it is worth considering Mifare DESfire cards, choose from EV1 and EV2. Please contact your system provider before upgrading from Mifare Classic to Mifare DESfire to check they have updated their software to support it.
Our trusted TopCard brand offers quality at an affordable price and these Mifare DESFire 4k contactless cards with NXP technology are no exception, plus we offer EV1 and EV2 options.
With radio frequency they can be used with a huge variety of access control systems and applications such as contactless ticketing, payment at vending machines or event ticketing.
The contactless chip inside each card operates at 13.56mhz, with a super-fast processing speed of up to 848 Kbits per second. The cards also come with a 4K byte memory size enabling it to hold multiple applications.
TopCard Mifare DESfire 4K is compatible with all brands of plastic card printer and supplied in high quality, dust free packaging ready to print. The true whiteness of these cards is perfect for overprinting in colour or mono.
Choosing between TopCard Mifare Desfire 4K EV1 and EV2 – what is the difference?
Even though most of the functionalities between EV1 and EV2 versions remain the same, there are some advantages offered by EV2 that may be worth considering.
APPLICATION LIMITS
EV1 can hold up to 28 different applications and 32 files per application, the file size can be determined when created. EV2, however, can hold an unlimited number of applications.
READ RANGE
The EV2 card begins to read sooner, while it is still moving toward the reader, this can make the transaction seem faster. (Depending on the reader power and antenna design).
BACKWARD COMPATIBILITY
Means you could purchase EV1 cards now and upgrade to EV2 later or vice versa because EV2 cards are compatible with EV1 readers.
SECURITY
EV1 and EV2 offer the same AES-128 encryption for data transactions. However, EV2 offers new security provisions along with multi-application features for better security. EV2 is certified with EAL5+ security, this is the same level of security as the chips used in e-passports and banking cards. Proximity check – the EV2 card can confirm to the reader that it is indeed near that reader and not a remote data stream from a hacker.

Mifare RFID cards have a very slight 7mm x 5mm indent where the chip is embedded inside the card. It’s only visible if you hold the card up to the light and look carefully, generally it’s positioned within a 20mm x 20mm area in the top left-hand corner. If you are printing onto the cards then please be aware that the print head on some ID card printers may miss this 7mm x 5mm chip area and leave a blank space. If that happens then you’ll need to adjust your card layout to accommodate not printing on top of the chip area. Another option is to purchase pre-printed Mifare Cards from us with your background design already in place, so all you do is print on the personalisation. Or instead use a retransfer ID card printer as it does not print directly onto the card. If you’d like a quote for either or a sample card to test then please contact us.
