Have a "naked" access card or fob and need to determine its appropriate number and facility code? If you're able to extract the binary or hexadecimal value then Proximity will do the rest. The first calculator of Proximity works one of two ways: By inputting the raw binary value of the card or by inputting the hex equivalent. To use the binary input, simply tap on the box and type in the binary value. The counter in the lower-right corner of the box will keep track of the amount of digits currently displayed. To use the hex input, tap on the box and enter the hex value. Once complete, select the bit length from the wheel below. This is only necessary when calculating from a hex value. After tapping on calculate, the output will be displayed. If there is more than one system in the same bit length, tap on Next to cycle through the different formats. The second calculator is simply the reverse of the first: 
Input the facility code, card number, select the format, and tap calculate to generate the raw binary value. More formats will be released in future versions so long as the information is acquired. If there's a format not on this app and you have the breakdown information, send it to me and I'll fulfill the request. Currently supports the following formats: 26 bits HID® Standard (H10301) 26 bits Indala 31 bits HID® ADT 33 bits HID® Standard (D10202) 34 bits HID® Standard (H10306) 34 bits HID® Northern (N1002) 34 bits Indala Optus 35 bits HID® Corporate 1000® 36 bits Simplex 36 bits Lenel 36 bits S2 37 bits HID® Farpointe (H10304) 37 bits HID® (no Facility Code) (H10302) 37 bits HID® PointGuard 37 bits Software House 40 bits Casi Rusco 40 bits XceedID 40 bits Honeywell (P10001) 48 bits HID® Corporate 1000® Disclaimer:

Verdict

The call

The clearest difference is price: Flipper Mobile App at Free against Proximity's $1.99. Flipper Mobile App also leads on review sentiment (69% vs 25%) and update cadence (every 3 weeks vs every 14 months). Proximity's advantage is rating (5.0 vs 4.5) and iOS requirement (12.0 vs 16.0). On ads, in-app purchases and device support there is nothing between them.

Flipper Mobile App is free to download; Proximity costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Proximity holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Flipper Mobile App has 313 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Proximity's written reviews are positive against 69% of Flipper Mobile App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Proximity ships an update every 14 months, Flipper Mobile App every 3 weeks. The most recent releases landed on November 8, 2026 and November 3, 2026 respectively.
