What is RFID/NFC? The technologies RFID (RadioFrequencyIdentification) or NFC (NearFieldCommunication) enablea non-contact data entry from passports, identity cards, credit card, bank cards, debit cards, etc. An RFID/NFC system always consists of: - The data carrier (chip and antenna) - The reader device (antenna and decoder) Magnetic or electromagnetic fields are used for data transmission. The frequencies used are LF: 125KHZ, HF: 13, 13.56 (reading distance: up to 1m) and UHF: 900MHz (Read and write accesses up to 3m. Why NFC protection for my data? - Even if RFID and NFC chips do not send their own signals, personal data without protective covers can be easily read without authorization using freely available readers or smartphones. Try it with your smartphone and an NFC card reading app! Why FreeHaveFun RFID Covers?- FreeHaveFun RFID Protective covers protects like all those commercially available Chip card protection sleeves before reading using HF (13.56 MHz) and UHF (900MHZ) frequencies. ✓ They are made of a durable aluminium-plastic composite. ✓ They are extra thin and light ✓ They are flexible and yet resistant ✓ They can be tailored (93x63mm, 140x110mm) - Due to the thin walls of the RFID protective covers, it is recommended to shift them when inserting between two fingers (see picture in the listing). - If you want to cut the NFC covers, please use for as straight a cutting edge as possible with a uniform edge a big pair of scissors or better still a cutting device like in the copy center - The ebook is in german language.

... is small and made of cardboard so it is good for recycling although it could probably be made smaller
The packaging is small and made of cardboard so it is good for recycling although it could probably be made smaller.They work very well does exactly what it says it does. Tried it against a card reader and it did the job. Heard about people going round holding card readers to bags and pockets so I will feel more at ease.Nice colour also
