UHF RFID Card have a good read range and a high data transfer UHF frequency band covers the range from 300 MHz to 3 GHz. This method of identification offers several advantages over traditional methods involving ID cards (tokens) or PIN numbers (passwords) for various reasons: (1) the person to be identified is required to be physically present at the point-of-identification; (2) identification based on biometric techniques obviates the need to remember a password or carry a token.
But if you want you can use the QR code feature built-in this app to generate QR code for the login your friend can login by scanning this code from any bar code reader apps, which they might already having and if not then they won’t mind it downloading it as it may come useful anytime.There is similar app called WiFi tap WiFi NFC, that works similar to Install Wifi.
860-960MHZ UHF RFID card made of PVC material and follow RFID technology, they are fully compliance with ISO 18000-6C protocol. It has long distance reading and can be used many places, such as container tracking, package tracking, warehouse management, super markets management or documents management. The classic chip options will Allien H3, Impinj Morza 4, NXP Ucode etc. We can print customer logo and artworks.
UHF (Ultra High Frequency) RFID card work at a ultra-high frequency. UHF RFID card are considered no on board power source. These cards must comply with the international recognized standard set by EPC global (UHF Gen 2). UHF frequencies usually offer better range (20-30 ft) and can transfer data quicker than LF and HF cards, but they take more power and are less likely to pass through materials. The EPC global UHF Generation 2 Standard enables the commercialized provision of mass adaption of UHF EPC technology for smart RFID cards. They main are used the supply chain management and logistics for widely use with especial consideration of European and US regulations to make sure that working distances of several meters can be realized.
RFID card is optimized for access control and offers superior performance when held in a user’s hand, hung from a lanyard, or displayed as an ID badge. These cards are 100% tested during manufacturing, which includes a programming test, and are ISO certified. UHF can also be used in ID card systems for securely protected door access control.
