Abstract

A pocket-size RFID reader apparatus having a contactless interface and a slot for insertion of a contactless smart card fob, and having a biometric sensor, thereby providing two levels of personalization. The apparatus may have a wireless interface; and a slot for insertion of a wireless SD I/O device. The apparatus may have a slot for insertion of an external memory device. The apparatus may have a mechanical connection (contact) interface. The apparatus may also have an RF interface for reading an electronic immobilizer within the apparatus.

Claims

1. Method of using an RFID reader comprising:

providing an RFID reader apparatus having a contactless interface, a slot for insertion of a contactless smart card fob, a biometric interface and a biometric sensor; and

disposing a switch under the biometric sensor for powering up the RFID reader apparatus when the biometric sensor is being used;

further comprising;

the RFID reader apparatus can enter several password protected sites or networks with a “

Single Sign-on”

by comparing a live and a reference fingerprint for authentication and reading the credentials and privileges stored in the contactless smart card fob for authorization to an access restricted site or network; and

updating encrypted keys for access to password protected sites in synchronization with an Internet Atomic Clock.

2. The method of claim 1,

further comprising:

providing a wireless interface; and

providing a slot for insertion of a wireless secure digital (SD) I/O device.

3. The method of claim 1,

wherein the apparatus is pocket-size.

4. The method of claim 1, further comprising:

providing the apparatus with an interface for interfacing with an Internet-capable appliance; and

the interface with the Internet-capable appliance in a Private Area Network is selected from the group consisting of Zigbee, NFC, Bluetooth, Ultra Wide Band (UWB), wireless USB, Infrared; and

the interface with the Internet-capable appliance for a Local Area Network is selected from the group consisting of 802.11 a/b/g, 802.11n and Worldwide Interoperability for Microwave Access (WIMAX).

5. The method of claim 1, further comprising:

emulating Multiple ISO Standard Protocols (Mifare, ISO 14443, ISO 15693, NFC, etc) by storing the communication protocols and the modulation type of each transponder type in memory, at mask level or in any other non-erasable memory form.

6. The method of claim 1,

further comprising:

Providing the apparatus with extended memory selected from the group consisting of EEPROM, (NAND) flash memory and hard disk drive (HDD).

7. The method of claim 1, further comprising:

the RFID reader apparatus can generate Transaction Authentication Numbers (TAN) and One-Time-Passwords (OTP) when in an electromagnetic field, in a wireless hotspot and can synchronize itself with an Internet atomic clock, for the purpose of time synchronous password generation and for recording events &

transactions with an exact time/date stamp.

8. The method of claim 1, further comprising:

the RFID reader apparatus can validate whether a user is allowed to access a network (logical access) or enter a facility (physical access) using a wireless interface; and

real time upgrading &

revoking of privileges or authorizing certain activities and access permissions can be implemented when the user is in a WPAN (wireless personal area network) or a WLAN (wireless local area network).

9. The method of claim 1,

further comprising:

a slot for receiving a secure digital (SD) card; and

the SD card has a hatch for receiving a SIM card, and performs a secure token function.

10. The method of claim 1,

further comprising:

a slot for receiving a secure digital (SD) I/O card; and

the SD I/O card has a hatch for receiving a SIM card, and performs a secure token function.

11. The method of claim 1, further comprising:

the RFID reader apparatus can perform one or more of the following functions;

monitor and record environmental parameters and can receive or transmit data via a wireless interface in periodic sessions to optimize power consumption;

store medical images in DICOM (Digital Imaging and Communications) standard file format; and

incorporate a real-time location system for patient location determination when an alert button is pressed.

12. The method of claim 1,

wherein:

the apparatus has a slot, hatch or recess for a WIM (Wireless Application Protocol Identity Module) card.

13. The method of claim 1, further comprising:

personalizing the RFID reader apparatus at two levels, firstly by inserting the contactless smart card fob with a cardholder'"'"'s credentials into the reader apparatus to give it a first layer of personality and secondly at an initialization stage, by the cardholder taking a digital imprint of their finger or thumb and storing the digital imprint in the memory of the RFID reader apparatus.

14. The method of claim 13, further comprising:

initiating a transaction with an external entity by the user pressing on the biometric sensor, which then measures a current fingerprint pattern for the user pressing on the biometric sensor; and

acknowledging a transaction by comparing the current measured fingerprint pattern with the template of the authorized user'"'"'s fingerprint which is stored in the memory of the RFID reader; and

sending a contactless or wireless authorization signal to the external entity.

15. The method of claim 1, further comprising:

storing a biometric profile of a user in the RFID reader apparatus, thereby making the apparatus unique to the user, as it authenticates the identity of the smart card holder by sensing the smart card user'"'"'s fingerprint and comparing it with the user'"'"'s biometric profile stored in its memory.

16. The method of claim 15, further comprising:

turning on the RFID reader apparatus when the biometric sensor is being used.

17. The method of claim 1, further comprising:

inserting a removable secure digital (SD) I/O device into the RFID reader apparatus, for wireless communication.

18. The method of claim 1, further comprising:

inserting a removable memory device into the RFID reader apparatus, for allowing the user to transport data from the RFID apparatus to another apparatus.

19. The method of claim 1, further comprising:

providing a mechanical connection (contact) interface.

20. The method of claim 1, further comprising:

providing an electronic immobilizer within the RFID reader apparatus for authenticating the user to perform a function in an external entity.

21. The method of claim 1, further comprising:

inserting the smart card fob with a cardholder'"'"'s credentials into the reader apparatus;

taking a digital imprint of the cardholder'"'"'s finger or thumb; and

storing the digital imprint in a memory of the smart card fob.
